Swizz Style Air Purifiers Guide

by

Swizz Style Company Info

Swizz Style is an Ohio based company that sells air purifiers and other home appliances. Swizz Style imports products of Swiss design produced by the company Stadler Form, which in turn is part of the MACH-Group. Stadler Form was founded in 1998, and is a company devoted to making designer household appliances that are both useful and emotionally appealing. Swizz Style is not the only company that distributes products by Stadler Form – other companies include Authentics Limited (based in the UK), Entrex Inc. (based in Japan), and Kohelet Import LTD (based in Israel).

Design, Testing, and Price Range

What sets Swizz Style’s air purifier line apart from others is the emphasis on designer appearance. Designed by award winning Swiss designers like Matti Walker, these air purifiers don’t just clean the air – they make a fashion statement as well. These air purifiers, which have been manufactured by Stadler Form for an unknown period of time, were tested and proved by leading European allergy and air quality labs.

The company claims that the air purifiers can run extremely quietly depending on which mode they are on. They are designed to reduce household allergies by removing smoke, dander and pollen from the air and contain fragrance dispensers to further freshen up the air.

Swizz Style Air Purifier Technology

Swizz Style’s Henry Air Purifiers utilizes a five step filter process. Air sucked into the purifier first passes through a HEPA filter and an activated carbon filter. These filters remove odors, dust, pollen and other air particles. The air then passes through a third filter, the Plasma-Cluster filter, which takes cares of even smaller particles that may have escaped the first two filters, such as dust mites, viruses and bacteria. The fourth filter, a TiO2 (titanium dioxide) filter, combined with a UV light, gets rid of anything that the third filter missed. The fifth and last filter is an ionizer that removes the very last bits of allergens from the air.

Regarding the HEPA filter and UV light, a professional reviewer has called into question whether the Henry Air Purifier uses real HEPA filters or not and whether a small UV light like the one the Henry has actually makes much of a difference in air purification.

The Viktor Air Purifier uses a new technology called the HPP Filter System. The Viktor contains a three-stage filter system, beginning with a pre-filter that traps large particles like pet dander, dust and hair. The HPP filter then removes smaller particles, bacteria and viruses. The carbon filter then eliminates odors in the air. Other than the fact that an international patent application is pending, there is little to no further information available about the HPP filter.

Zojirushi Air Purifiers Guide

by

Zojirushi Company Info

With over 90 years of experience in making household and kitchen appliances, the Zojirushi Corporation has expanded their products to offer two air purifiers that have an ultra slim design and attractive appearance. The company made a name for itself when it launched a glass-lined vacuum bottle that was nothing short of quality and innovative materials back in 1948.

After establishing its credibility, the Zojirushi Corporation began branching out into other products, using top-of-the-line technology to bring forth rice cookers, electric boilers, electric warmers and kettles. Although it is unknown how long Zojirushi has been making air purifiers, the products make up a light sales volume for the company.

What Zojirushi prides itself on is that they use innovative designs and cutting-edge technology to introduce products that are stylish and easy to use. Zojirushi operates on a global level, with its headquarters being located in Osaka, Japan and service centers located throughout the world. In 1987, Zojirushi America Corporation was established and run out of California.

Air Purifier Price Range

The air purifiers offered through Zojirushi are very similar, except one is a bit larger than the other and offers more features that make it more favorable to use. What makes these air purifiers stand out is that they are small, compact and super slim, measuring only 5 inches thick and being able to fit in virtually any space. They are also quiet and near silent when placed on low settings, which is why they are a popular buy for college dorm rooms or home offices.

Clean Air Delivery Rate Certified

The Zojirushi PA-LTC10 air purifier is AHAM certified and its clean air delivery rates add up to 84 for dust, 69 for smoke and 81 for pollen but is only based on 110 square foot room size. The units are best served in rooms of that size or smaller and their ultra sleek design makes this possible without taking up too much space. Zojirushi also ensures that their products are easy to use and maintain and their air cleaners fit right into this category. There is a convenient air quality monitor that allows consumers to check the quality of the air, as well as a shut-off timer and remote control.

Zojirushi Air Purifier Technology

The air cleaners use HEPA-type filters and carbon filters, which need to be replaced every two years or so. The company warns that heavy dander and smoking for example, will shorten the lifespan of the filters. However, for a pack of four filters (2 HEPA-type and 2 carbon), the bundle only costs $48. While there are many great benefits to Zojirushi air cleaners, reviews warn that the low powered fans and the sleek design compromises the power of the cleaners. In addition, there is no prefilter to trap larger particles and there is some debate as to the efficiency of HEPA-type filters instead of true, certified HEPA filters.

The Top Ten Sources of Indoor Air Pollution in the Home

by

Introduction

Indoor air pollution can be a serious health risk. Studies by the Environment Protection Agency have shown that the air inside buildings is often two to five times more polluted than the air outside, and sometime much more.

One thing we must keep in mind is how many different sources of pollution can contribute to lowering the air quality of our indoor spaces. The term “indoor air pollution” is an umbrella which covers a wide array of unhealthy material which can have different effects on the human body. This article will examine (in no particular order), the ten most common sources of air pollution in American homes, as identified by the U.S. Consumer Product Safety Commission (CPSC). For each item, we will focus on three things: what these pollutants are and where they come from, what health effects they have on humans, and how you can deal with them so that your home is as pollution-free as possible.

CPSC recommends stopping the sources of indoor air pollution as the first strategy to keep the air clean in your home. The second is improving ventilation in your home, so that the following toxins do not stay trapped inside. The third is making use of quality air purification devices.

Most of the information below is based on material provided by the Environmental Protection Agency (EPA) or the CPSC.

1. Radon

(Source:Wikipedia.  Author: Greg Robson)

Radon is a highly radioactive gas that can be introduced into the home through the ground beneath it, well water, and the building materials that constitute your house or apartment. Part of what makes radon so dangerous is the fact that it is colorless, tasteless, and odorless, and that it produces no immediate symptoms, which means that you will normally be completely unaware that you are inhaling it. The CPSC states that one study has indicated that radon is over three times as prevalent in homes as in the outdoors.

Inhalation of radon is linked to lung cancer, and the CPSC estimates that it causes between 7,000 and 30,000 lung cancer deaths every year. For smokers, radon exposure increases the risk of cancer even further, as radon can attach itself to the smoke and lodge itself in the lungs.

Fortunately, testing for radon is relatively inexpensive and easy to do using readily available radon testing kits. It is a good idea to test your home, and if radon levels are higher than 4 pci/L, take steps to reduce it. Contact a professional to help you.

Air purifier effectiveness – None.  Radon must be vented to the outdoors.

2. Environmental Tobacco Smoke (Secondhand Smoke)

The chemicals that resulting from smoking will remain in the air after the cigareete has been finished.

The health risks of smoking are too well known to need any in-depth discussion here. Environmental tobacco smoke carries risks similar to that caused by directly smoking. These include lung cancer and heart disease as well as irritation of the eyes nose etc. It can also exacerbate asthma and cause other health problem.

This is one source of pollution that is very easy to control: simply don’t smoke inside your home or let others do so. By choosing to keep your home smoke free, you can eliminate one major source of indoor air contamination entirely.

Air Purifier Effectiveness – Medium.  Many air purifiers successfully remove a portion of tobacco smoke from the air.  Effectiveness varies by model.

3. Biological Sources

(Image Author: Infogramation)

Remember that you are not the only life form that calls your house or apartment home. From pets, to insects, to mold and mildew, all the living things around you make their own contributions to the pollution in your air.

Biological pollutants can cause irritation of the eyes and nose and asthma. There are plenty of reasons you don’t want bugs, mold, or mildew infesting your home; their contribution to air pollution should be one of them.

Unlike environmental tobacco smoke, there is no way to completely rid your home of this pollution source. But you can still take some simple steps to reduce it. Moisture encourages the growth of mold and mildew, for instance, so minimize moisture by making sure you have no leaks and using exhaust fans and ventilators if you have them. Be sure to dust and vacuum regularly as well. Wash your bedding in hot water to kill the mites that like to make their home there, and wash your rugs as well. Keep your home clean in order not to attract cockroaches and other pests. One caution to keep in mind: try to avoid using chemical pesticides when other means of pest control are available, as pesticides themselves are a source of indoor air pollution as well (see #9 below.)

Air Purifier Effectiveness – Minimal.  Some airborne mold particles may be captured but mold must be removed at the source where it grows.

4. Carbon Monoxide

Like radon, carbon monoxide (CO for short) is colorless, tasteless, and odorless, and therefore particularly insidious. Environmental tobacco smoke is one source of CO, but there are many others, including gas stoves and heaters, wood stoves, chimneys, and furnaces. Automobiles also produce CO, so attached garages increase the risk as well.

CO attacks, among other things, your bloodstream and central nervous system. Exposure to low-level doses of carbon monoxide will leave you feeling sluggish, which means an inexplicable lethargy is a good early warning sign. Heavier levels of ingestion can cause nausea, dizziness, headaches, and a lack of coordination. Carbon monoxide is fatal when you come into contact with too much of it.

Keeping the CO sources listed above in proper working order and well ventilated will reduce the risk of CO poisoning. Also, you should install CO detectors in your house or apartment; they are cheap and easy to find and should be a standard accessory in every home.

Air Purifier Effectiveness – None.  Sources of CO2 pollution must be eradicated.

5. Nitrogen Dioxide

(Image author: SJu)

Nitrogen dioxide (NO2) comes from many of the same sources as carbon monoxide and carries with it similar health risks. In addition, it can also help produce another very dangerous chemical, ozone. Unlike CO, however, NO2 possesses a sharp and easily detectable smell and a reddish-brown color.

Reducing NO2 can be done using the same methods recommended to reduce CO. Since it is more easily detectable than radon or carbon monoxide, even without the aid of any equipment, it poses less of a threat, but you should never take anything for granted when it comes to a deadly chemical like this one.

Air Purifier Effectiveness – None.  Sources must be eliminated or reduced to safe levels.

6. Organic Gases

“Organic gases,” or “volatile organic compounds” (VOCs), is something of a catch-all term for gases that are emitted from many different sources. Among the common sources for VOCs identified by the EPA are paint, cleaning supplies, pesticides, glue, printers and photocopiers, permanent markers, and certain building materials. As you can see, your home probably has many VOC sources, so being aware of them is important.

The effects of organic gases are likewise various, and range from irritation of the eyes, nose, and throat to dizziness and nausea to even more serious problems, including cancer and damage to the central nervous system. Different gases have different levels of toxicity.

One way to limit the concentration of VOCs in your home is to store VOC-producing material outside when possible. Do not buy unnecessarily large quantities of things like cleaning supplies, so that they are not sitting unused in your home giving off gases. Also, use them in ventilated areas when you can and always follow manufacturer’s instructions—often they are there to help limit you exposure to the gases.

Air Purifier Effectiveness – Minimal.  Some air purifiers can trap VOC particles but they must had the filtration system to accommodate, most don’t.

7. Respirable Particles

Respirable particles are simply small bits of matter that can easily be inhaled (“respire” is another word for “breathe”). Environmental tobacco smoke contributes to their presence, as do fireplaces, kerosene heaters, and wood stoves.

Respirable particles, like many other indoor air pollutants, can irritate the eyes, nose, and throat, and they can also cause ailments such as bronchitis. They are a cause of cancer as well.

Reducing their presence can be accomplished by proper maintenance of the devices that cause them, by ensuring good ventilation, and by not smoking indoors. Homes without the sources listed above rarely have significant levels of repairable particles, so long as they are well ventilated.

Air Purifier Effectiveness – Medium-High.  Depending on the model, some air purifiers are quite effective at removing particles from the air.

8. Formaldehyde

(Image Author: Simon Eugster)

Formaldehyde, or CH2O, is an organic compound that exists as a gas at room temperature. Formaldehyde is invisible, but has a distinctive pungent smell. Common sources of formaldehyde in the home include glues, environmental tobacco smoke, and textiles such as durable press drapes. But the top source of formaldehyde in most people’s homes is the presence of pressed wood containing urea-formaldehyde resins in building materials and furniture: this category includes particle board, hardwood plywood paneling, and, above all, medium-density fiberboard. Homes built in the 1970s were sometimes insulated with urea-formaldehyde foam insulation (UFFI), which is a major source of indoor formaldehyde pollution.

In high enough concentrations, formaldehyde can cause irritation of the eyes, nose, and throat, coughing, rashes, and fatigue. It may also be a cause of cancer and other serious health problems.

If you do not have UFFI as insulation in your home, you probably do not have excessive levels of formaldehyde. To keep formaldehyde at a minimum, reduce the humidity and moderate the temperature in your home. In the future, use exterior-grade pressed wood products, which release less formaldehyde because they have different resins.

Air Purifier Effectiveness – Minimal-None.  Some air purifiers can remove a small amount gases but sources of formaldehyde pollution must be removed.

9. Pesticides

Pesticides’ very purpose is to kill, so clearly, you do not want to be continuously inhaling them at home. Pesticides release a variety of chemicals into the air. Pesticide containers in the home are the primary source of this pollutant, but pesticide can also be unwittingly tracked in from the yard by those who use them outside.

Pesticides can irritate the eyes, nose, and throat, and they are detrimental to the central nervous system and the kidneys. They are also associated with an increased risk of cancer.

To reduce the pesticides in your indoor environment, avoid using chemical pesticides when possible. If you do need to use them, follow instructions on the label, do not use excessive amounts, and make sure you keep the area well ventilated after use. Do not purchase more than you need, so that you don’t have extra pesticides resting unused in your home giving off fumes. It is best to store pesticides outside rather than inside. If you need the services of a pest-control company, check its credentials before you allow it to spray harmful chemicals in your house.

Air Purifier Effectiveness – Minimal-None.  Pesticide sources should be stored outside the home.

10. Asbestos

Finally, asbestos is a type of magnesium silicate fiber that was once commonly used in home construction for its ability to insulate the home and resist fire. Asbestos fibers are so small that they can easily be inhaled by someone without the person knowing it. Today, many forms of asbestos are banned by the federal government, and even those that are not are rarely used. Therefore, asbestos is a major risk in older homes rather than newer ones.

Asbestos produces no immediate symptoms, so there are no early-warning signs. In the long term, it can contribute to abdominal cancer, lung cancer, and mesothelioma. There is even a condition known as asbestosis, which occurs when the fibers cause scarring in the lungs.

If your home has asbestos, this does not necessarily mean that you are in danger. If the asbestos is of good quality and left undisturbed, it will not release fibers into the air to be inhaled. If some operation needs to be performed on your home that might lead to the asbestos being disturbed, it is best to use professionals. If you are worried about asbestos levels in you home, the wise action may be to seal the asbestos off rather than try to remove it, which may just lead to more asbestos being released into the air.

Air Purifier Effectiveness – Varies.  Many air purifiers can filter asbestos particles suspended in the air column down to .3 microns.  However, asbestos sources should be removed by experts and surfaces cleaned if asbestos contamination is suspected.  Should never rely on an air purifier alone to deal with asbestos pollution.

Conclusion

As you can see, although there are numerous sources of indoor air pollution, many of them can be fought using relatively simple steps. Also, some actions will help to reduce multiple sources: keeping humidity in your house or apartment low, for example, and not storing excess chemical products inside. By being aware of the dangers and following the advice above, you may significantly improve the quality of the air you breathe at home. Remember also to ensure good ventilation, so that the sources you can’t completely eliminate will not stay trapped inside.

Tiger Air Purifiers Guide

by

Tiger Company Info

Tiger Corporation is a well-known company that is located in Kadoma City, Osaka, Japan. They have been in business since 1923, being a manufacturer of stylish kitchen accessories, including such products as rice cookers, kettles and coffee makers. Proud of all their small appliances, Tiger focuses on items that can be used on a daily basis, while improving the lives of their consumers. They promise and deliver satisfaction, which is why the company has a reputable standing in the Japanese market.

In 2002, the company expanded and opened the Japan Tiger Corp of USA branch located in Torrance, California. With a focus on maintaining stylish and contemporary products, the company introduced their first air purifier in 2005 called the Tiger Healthy-Aire Air Purifier. It is difficult to predict whether Tiger will expand their line to include more air cleaners, as this model is the only one on the market and remains a featured product through Tiger.

Only One Air Purifier Model Offered

The Tiger Healthy-Aire Air Purifier has received mixed reviews, especially since it is the only air purifier the company has offered over the last five years. Whether the company will offer more air cleaners is yet to be determined, but they have been proud to share this model with consumers across the US and Japan. Fortunately, the Tiger air cleaner is affordable. Some sellers have decided to stop selling the air purifier, suggesting a soft market, while others still stand behind this inventive unit.

Tiger Air Purifier Technology

Following suit with Tiger’s trendy products, the Healthy-Aire Air Purifier fits perfectly into this image. With a silver plastic house and blue screen, the unit is small, portable and convenient. When running on the ionization mode, the blue screen lights up with gentle illumination. On low speed, the unit is quiet and contaminants are able to enter the unit from three different sides for maximum cleaning.

Since Tiger focuses on products that improve lifestyle and are low maintenance, the air purifier has a remote control, as well as various fan speeds and timer delays. With its small and compact frame, the Healthy-Aire Air Purifier is ideal for undersized rooms that are 110 square feet or less, such as home offices, dorms and bedrooms. It removes odors and airborne particles using a two-stage filtration system as well as ionized air cleansing technology. The air cleaners are also fairly inexpensive to maintain, as they will need to be changed out every two years.

Currently, Tiger Corporation is only offering one air purifier. This model can be purchased directly through Tiger or through outside vendors.

UV Air Purifier Guide

by

Introduction: Ultraviolet Light

Ultraviolet (UV) light is a form of radiation with very short wavelengths—too short to be perceived by the human eye. This form of energy is called “ultraviolet” because it has shorter wavelengths than violet light, which has the shortest waves of any kind of visible light.

Although UV radiation can be dangerous, and you can often hear reports about the dangers of UV rays coming from the sun, ultraviolet light is not always detrimental to humans and has a variety of uses. Some air purifiers include specialized lights that produce ultraviolet rays as a way to kill living pollutants.

EPA Studies – Effectiveness of UV Air Purifiers

Based on the available test information, the actual success rate of UV purifiers is mixed. According to the EPA’s official guide on indoor air cleaners, well-designed ultraviolet air cleaners are able to:

Air Purifiers

 

“[Air purifiers] reduce the viability of vegetative bacteria and molds and to provide low to moderate reductions in viruses but little, if any, reduction in bacterial and mold spores.”

Factors Influencing UV Air Purifier Effectiveness

It also states that various factors influence the effectiveness of UV purifiers, including

  • UV irradiation dose
  • System design and application
  • System operation characteristics
  • Microorganism targeted for deactivation.

Thus not all UV air purifiers are the same, and UV lights will be more or less useful depending on the environment they are placed in.

Furthermore, tests have shown that UV cleaning alone does not reduce dust mite problems or allergic reactions to mold—the latter because mold is still dangerous to humans even if it is dead. The Environmental Protection Agency states that the only solution to mold is to have it removed. Ultimately, the EPA declares that further testing is necessary in order to better understand just how useful ultraviolet air cleaners really are.

Conclusion – Ultraviolet Air Purification Effectiveness

  • Well designed systems can reduce vegetative bacteria, molds, and some viruses
  • Little if any reduction in bacteria or mold spores
  • Ineffective against particles like dust or dust mites
  • Further research is needed to measure absolute effectiveness

Vollara Air Purifiers Guide

by

Vollara Company Information

Vollara is a company that manufactures and distributes products related to weight loss and health. Examples of their products include dietary supplements, weight loss pills and air purifiers. Vollara is not the first incarnation of this particular company. The company was founded in 1986 under the name of Alpine Industries, and later changed its name to Ecoquest International. Ecoquest International was purchased by Aerus Holdings LLC in 2010, which in turn is owned by Engles Urso Follmer Capital Corporation. Vollara is related to Elextrolux, USA, another company owned by Engles Urso Follmer.

Company Claims and Past FTC Troubles

Vollara says it creates products that are in line with their core values of environmentalism, science, integrity and government regulations. However, when the company was known as Alpine Industries and Ecoquest International, it ran into a lot of trouble due to their health claims regarding their air purifiers.

In 2000, the Federal Trade Commission and US Justice Department ordered the company to stop claiming that their air purifiers provided relief from medical conditions or were effective in removing pollutants from their air. The FTC said that Alpine and Ecoquest did not have reliable scientific evidence supporting these claims.

When Ecoquest was bought and renamed Vollara, many hoped that the company would turn over a new leaf. However, from the start Vollara has not done a good job regaining consumers’ trust, especially when Vollara decided to cancel warranty coverage on products sold by Ecoquest.

Vollara Air Purification Technology

The company touts its ActivePure technology but barely explains how it works. It describes ActivePure technology as basically diluting hydrogen peroxide and misting it through the air, and says it uses hydroxyl-producing photo-oxidation. One marketing pamphlet explains that

“technology is the stuff in your box that makes the…thing happen…that’s really all there is to know…”

Vollara claims that ActivePure is the same technology used to purify air in space shuttles. According to university studies, ActivePure can kill over 99.99% of bacteria, viruses and mold, including Staph and the Avian Bird Flu.

NQ Air Purifiers Guide

by

NQ Industries Company Info

Since 1993, NQ Industries has been manufacturing air filtration and air sterilization devices, utilizing UVGI (ultraviolet germicidal irradiation), HEPA (high efficiency particulate air) filtration, UVPCO (ultraviolet photo catalytic oxidation) and activated carbon filtration technologies.

The company began as a supplier of tuberculosis isolation units to hospitals and homeless shelters. NQ’s primary product lines are still targeted to medical care facilities, but the company has branched out into military and food industry applications as well, and the company also makes air treatment systems for commercial and residential use.

In isolation rooms, operating theaters, and other hospital setting, air purity is of critical importance. Today NQ’s air treatment systems are used in over 370 healthcare facilities in 37 states, as well as by U.S. armed forces (Army, Navy and Air Force) and numerous school facilities throughout the nation. NQ products have a strong international following as well, and in 2003 the company donated several air purifiers to help combat the SARS (severe acute respiratory syndrome) outbreak in Hong Kong.

Air Purifier and Sterilizer Price Range

NQ’s filtration and sterilization devices are standalone products designed to be utilized around the clock, 365 days a year. NQ sells its products through a comprehensive network of dealers. List price for the basic Clarifier-Standard NQ Industries Air Purifier, designed to be used in the home.

While the majority of air purifiers manufactured today are made overseas, all components used in NQ products – with the exception of the blower – are manufactured in the United States from American produced steel. NQ Industries eschews the use of plastics in its products in order to guarantee that its customers receive the cleanest air possible.

NQ Air Purifier Technology

Each NQ product is designed to accommodate a slightly different process, but generally all of them work by trapping particles larger than 10 microns in size with pre-filters. Then air is circulated through some combination of specialized filters like activated charcoal or HEPA filters to remove odors, volatile organic compounds and other chemicals, and particulates as small as 0.3 microns. Finally air is circulated into a specialized chamber where UVGI is used to destroy biological contaminants such as bacteria, viruses, fungi, and mold. Purified air is then discharged back into the room.

Most air purifiers that deploy UVGI technology use it only on the surface. NQ Industries pioneered the use of the single pass UVGI kill chamber.

NeoAir Air Purifiers Guide

by

NeoAir Company Info

NeoAir manufactures high grade air purifiers that range from typical HEPA and carbon activated filtration systems to high tech ultraviolet filtration for hospital grade sterilization. New NeoAir filter units are only available through online sources and can not be found in retail outlets. The brand has been in the marketplace long enough to have developed a healthy positive reputation among consumers who have posted glowing reviews of the filters on several different retail websites.

NeoAir Air Purifier Technology

NeoAir air purifiers are manufactured in China and exported to a United States base of operations in Miami, Florida. These filters have been available to United States customers for approximately two years. The company strives to remain environmentally safe and claims that that their air filters emit very little ozone. NeoAir states that their pre-filter and HEPA/Carbon filters enjoy long life spans and do not need to be replaced very often when the units are used on a daily basis.

Since the air purifiers utilize a multi-filter system, owners will need to replace the pre-filter as well as the HEPA or Carbon filter at different times. The pre-filter tends to need replacement more often than the internal HEPA filtration system due to the fact that it collects more particulates than the HEPA/Carbon filter.

All of the units offered by NeoAir were created with portability in mind. Even the more powerful units are designed to be moved comfortably from room to room. NeoAir’s innovative multi-filter design includes a pre-filter that catches particulates from the air before the air passes through a more delicate HEPA or Carbon filter.

Some units include a third layer of filtering that involves the use of UV light filters or sterilization filters for medical uses. Some NeoAir purifiers are designed specifically to remove mold and mildew from basements, boats, and other areas that acquire moisture on a regular basis. NeoAir is committed to finding affordable ways for consumers to improve the air that they breathe through researching and developing new technology in air purifiers of all types.

Air Filter Price Ranges

Prices may vary depending on the website where you shop. Shipping and handling charges will also impact your final cost. Customers who need more than one air purifier can take advantage of discounts that NeoAir offers for purchases of two or more air filters at once.

Oransi Air Purifiers Guide

by

Oransi Company info

Oransi is a company based in Austin, Texas that has primarily been manufacturing and distributing air purifiers for 15 years. The company was started by Peter Mann, whose child suffered from asthma. Because of this, Oransi strives to make air purifiers that can especially help people suffering from asthma and allergies. Peter Mann also started Alen Corporation, another air purifier company. Oransi prides itself on a business model of giving back to the community by employing stay at home moms, encouraging employees to work from home to cut down on motor emissions, and donating 5% of their income to promoting student interest in the sciences.

Oransi Air Purifier Technology

The v-hepa air purifiers are energy star qualified and operate at a low cost. The company states that they are the quietest HEPA (high efficiency particulate air) air purifiers on the market, and are RoHS lead free directive certified. Oransi’s HEPA filters utilize two filters to clean the air. Air will go through a pre-filter which traps large particles. By filtering out the biggest particles, the pre-filter helps extend the life of the next filter – the HEPA filter. The HEPA filter removes 99.97% of dust, pollen, bacteria, viruses, dust mites, smoke and other particles that are between 0.5 and 2.0 micrometers in size. The filter also utilizes low air flow resistance so it can function more powerfully and effectively.

The v-hepa filtration system also includes negative ionization, which uses chemical injection technology. Negative ions are molecules that have an additional electron. This electron makes the ion negatively charged. Because the ion is charged, when it touches another element like a particle of dust, it sticks to it. The air purifier sucks in dust laden air, and the negatively charged ions stick to the dust and trap it inside the machine.

To entice new users, Oransi is offering three additional HEPA filters when you buy a new v-hepa air purifier. These three filters should keep your purifier running for the next two years. The purifiers are small and less than six inches deep so they can fit easily and unnoticeably into corners and against walls. The company claims that compared to other air purifiers, these are very quiet machines, and that they are easy to use and incredibly effective at removing particles from the air. The air purifiers do not weigh more than 10 pounds, and thus are easy to move around.

These v-hepa air purifiers have a v-lock magnet that creates a strong seal around the air filter. This seal locks the filter cover in place and makes sure that all the air inside gets filtered properly. While other air purifiers cost anywhere from $3-$8 in electricity per month, it only costs $2 a month in electricity to run a v-hepa air purifier. This filter has safety certifications from ETL, GS and CE as well as the RoHS lead free directive, and is made of fire-resistant ABS materials. As a safety feature, if someone opens up the cover of the air purifier, it will stop working. Oransi stands by its v-hepa purifiers, going so far as to offer a 10 year warranty and a 30 day money back guarantee.

The two ionic air purifiers use negative ionization to remove odors and particles from your room or fridge. They work silently, do not require you to replace the filters and come with a one year warranty.

The choice of “Healthier, Easier, Smarter” as the Oreck company motto is just one of things that point towards the fact that Oreck brand-originator David Oreck appeals to the consumer’s sense of self-entitlement when trying to market his products.

The company that is now known as The Oreck Corporation opened its doors during 1963 when David Oreck – with the help of his family – began to bring to life his vision for the manufacture and sale of premium vacuum cleaners, air purifiers and related household implements. At the time of writing, The Oreck Corporation had been in business for almost 50 years, and, apart from its manufacturing plant, which is situated in Cookeville, TN, and its country-wide franchised offices, it also boasts premises in Canada and England, where it does business as Oreck Canada and Oreck Holdings LLC respectively.

Oreck air purifiers, vacuum cleaners and furnaces are available throughout North America, Canada, the United Kingdom and Europe, and the company’s clients – which primarily consist of international hotel franchises – can buy them either in stores or online. Oreck supplements the sales of their main lines, which they market as their “floor care products” and their “air care products”, with that of related items, including their “home goods” like their location-specific refrigerator air purifier as well as their cleaning products, which have been developed to sanitize, among other locations, the kitchen and bathroom, pet places, hard floors and upholstery.

Oreck also offers consumers a full range of supplies and accessories, including the air filters, scent cartridges, odor absorbers and mounting kits that are specific to their air purifiers. Oreck does not market their air purifiers under any brand name other than their own as, no doubt, they wish to foster international recognition of their distinctively named Oreck brand.

Consumer Reaction to Oreck Air Purifiers

A study of public opinion regarding the Oreck brand of air purifiers may, however, reveal that The Oreck Corporation’s air purifier lines are, perhaps, not as competitive in today’s market as Oreck management may wish. On the one hand, Oreck infomercials are well known for inducing consumers to order their products – which all boast numerous extremely positive buyer testimonials – but, on the other hand, these same consumers have a tendency to later report that the Oreck air purifiers sometimes need frequent cleaning and, perhaps, do not completely purify the air.

Price Range

Apart from the compact refrigerator air purifier, Oreck offers its customers three different air purifier models: the ProShield purifier, the ProShield Plus purifier and the Tower purifier.

Oreck Air Purifier Technology

The Oreck Corporation’s website is, unfortunately, not extremely forthcoming about the technical specifications of their air purifiers. Oreck does, however, claim that its patented Truman Cell (TM) filter technology is superior to HEPA-certified filters as the Truman Cell allegedly “never needs to be replaced”.

Oreck Air Purifier Models

The Oreck air purifiers customers can presently choose from comprise:

  • ProShield: this boasts Truman Cell technology, which electronically charges harmful air particles preparatory to their being “pulled out of the air”;
  • ProShield Plus: this features both the Truman Cell filter and the Helios Shield permanent odor absorber;
  • Tower: Truman Cell technology is, again, this unit’s main claim to fame.

It should be noted that Oreck’s website describes all units in somewhat general terms – like being “energy efficient” and utilizing “Quiet Silence Technology” – but that these terms are, on the whole, not elaborated on.

Haier Air Purifiers Guide

by

Haier Company Info

Haier is an international supplier of household appliances headquartered in the people’s Republic of China and is currently considered the world’s largest white goods manufacturer. Founded in 1920 as a refrigerator factory, it was turned into a state-owned enterprise in the 1950s, which was foundering until the 1980s when a German company, the Liebherr Group, stepped in and diversified the Haier brand. Haier has since become the most recognized Chinese name brand and has extended their market from household appliances to mobile phones and computers and established worldwide distribution.

Air Purification Products and Warranty Info

Haier makes three models of air purifiers, all of which are Association of Home Manufacturers (AHAM) certified and the two larger models are ETL/CELT certified. All three models contain TrueHEPA filters that can remove 99.97% of the particles down to 0.3 microns. Each model has the same basic filtration setup that combines the pre-filter with the carbon filter to help remove odors and trap large particles, lint and hair as well as the main HEPA filter.

Each size Haier air purification unit has a 3-speed fan, all with quiet operation motors, and plastic grills that feature a 45° angle for the air outlet. The fan should be lowered to a Level 1 before turning off./p>

Haier offers a replacement filter pack that contains 2 carbon pre-filters and 1 TrueHEPA filter that can service the unit for 1 year and cost about $20 per pack. The two larger units come with a 1 year warranty for parts and labor and all three have a 5 year warranty for the sealed system.

Panasonic Air Purifiers Guide

by

Panasonic Company info

The Panasonic brand is known the world over, as is the company’s short but significant brand slogan: “ideas for life”.  The Panasonic Corporation’s headquarters are in Osaka, Japan, and this multinational corporation started up in 1918 as the Matsushita Electric Housewares Manufacturing Works. At the time of writing, the corporation has 680 subsidiaries, which are divided up into 14 different business domains. Panasonic is one of the largest corporations in the world and boasts market share in almost every country on earth.

Panasonic specializes in the manufacture and sale of all types of electronics products, which products are broadly classified into three groups: consumer products, business products and industrial products. The Panasonic air purifiers fall into the consumer products’ group, and, although these purifiers may have been manufactured under a different brand name in the past, in 2008 the corporation consolidated all separate brand names into one umbrella brand: “Panasonic”.

Air Purifiers Sold Under a Few Different Names

Panasonic continued to sell air purifiers under only the Panasonic brand name until December 21st, 2009, when it purchased Sanyo, another large Japanese electronics company and one that already had its own brand of air purifiers. At present, Panasonic-manufactured air purifiers are marketed under both the Panasonic and the Sanyo brand names.

Apart from Sanyo – which markets Panasonic air purifiers under the Sanyo brand name – a further two of the Panasonic Corporation’s 680 subsidiaries manufacture and sell air purifiers: Panasonic Corporation of North America and Panasonic Ecology Systems Co Ltd. Although both the multi-award winning Panasonic and Sanyo brands have been known for their product excellence for many years, it is unclear exactly when the companies began to develop and manufacture their air purifier lines.

Price Range

Consumers looking to buy an air purifier from the Panasonic Corporation of North America, which markets three distinct models. Those looking to buy from Panasonic Ecology Systems Co Ltd, which does business out of Hong Kong and supplies mainly the Middle Eastern and Asian markets, will have to contact the company directly in order to ascertain unit prices as the company’s website is silent in this regard. Panasonic Ecology Systems Co Ltd has eight distinct models of air purifiers for sale.

Panasonic Air Purifier Technology

The Panasonic Corporation of North America claims that their air purifiers both “reduce noise” and “save energy”. It also claims that their units’ High Efficiency Particulate Air (HEPA) filters only have to be replaced every three years and remove over 99.5% of all noxious air particles larger than 0.3 microns. The purifiers marketed by Panasonic Ecology Systems, on the other hand, claim to sport sophisticated “nano” technology that “senses, attacks and inhibits” as many as 28 separate strains of allergens and viruses. This nano technology is apparently aided by such features as the units’ front and upward 3D Circulation Airflow systems and their anti-allergen substance, Super Alleru-Buster.

Hamilton Beach Air Purifiers Guide

by

Hamilton Beach Company Info

Hamilton Beach is a Virginia-based corporation that manufactures a wide variety of home appliances, such as blenders, drink mixers, toasters, and irons, as well seven different models of air purifiers, most of which include the term “True Air” in their names. Hamilton Beach also produces devices intended to reduce allergens or odors, though these are different from air purifiers and are not covered here. The company is a major player in its field and has been in business since 1910.

Hamilton Beach Air Purifier Technology

All of the different models offered by Hamilton Beach make use of high efficiency particulate air (HEPA) filters, which target particles that pollute the air, but do not address polluting gasses or contribute to odor reduction. Certain other Hamilton Beach models, however, also use other methods in addition to HEPA, including: carbon pre-filters, which reduce odors; ultraviolet lights, which are damaging to airborne bacteria that can cause diseases; ionizers, which negatively charge air particles to attract and entrap positively charged pollutants; and zeolite, which Hamilton Beach markets as specifically intended to reduce pet odors. Zeolite is a mineral commonly found in laundry detergents, water purifiers, and cat litter. For details about which models use which methods, see below.

Price Range of Available Air Purifiers

Hamilton Beach’s air cleaners are mostly quite affordable when compared to the average prices of other cleaners.

Some of Hamilton Beach’s air cleaners are notable for their auto-adjusting fans which change speed on their own in response to how polluted the environment is. Some customers, however, have complained about the noise made by the fans.

Pure Air Air Purifiers Guide

by

Pure Air Systems Company Info

Pure Air Systems is celebrating 25 years of service in the production of commercial-grade air purifiers. The company states on their webpage that they offer the best filtration systems on Earth, with a focus on using the latest technology that does not compromise the environment. Pure Air Systems has been in business since 1985 and is located in Indianapolis, Indiana. They offer a complete line of air cleaners that use HEPA and carbon base filtration systems and have experienced a 20% growth rate on an international level each year.

Allegedly, Pure Air Systems has a reputation for manufacturing high quality, high performance HEPA air filtration systems that are dependable and reliable for residential homeowners. Yet what makes this company unique to its competition is that it has been the one to offer many “firsts”. The company was the first to offer commercial-grade air cleaners for residences and the first to use GE ECM digitally controlled speed motors, an appeal to the international market. Furthermore, Pure Air Systems claims to be a green company, reducing waste and using less energy.

Pure Air Systems Air Purifier Technology

The steel frames of the air cleaners account for less waste and disposing of the parts. The motors on the air cleaners are energy efficient and have Energy Star ratings. In fact, the GE ECM speed motors have accounted for using 50% less electricity than other motors on the market. Besides having a general concern for the environment, Pure Air Systems also uses commercial-grade parts throughout their air cleaners, including HEPA filters that are certified at 99.99% in trapping airborne particles. With a focus on the residential market, new advances have been made, such as the ability to use a by-pass arrangement to install a whole-house filtration system instead of having individual units in each room.

In fact, many of Pure Air System’s air cleaners can be used as either portable units or attached to a HVAC system. While all of the products use high-performance HEPA filters, the air cleaners can also be purchased with carbon filters instead. Although the company focuses on the residential market, their knowledge in using commercial-grade products has also led them to offer a complete line of commercial air cleaners as well.

Holmes Air Purifiers Guide

by

Holmes Company Info

Holmes has been in the air purifier business since 1982. The Holmes brand is a subsidiary of the Jarden Corporation, which owns other brands such as Sunbeam, Mr. Coffee, and Crock-Pot. Jarden also owns another air purification company, Bionaire.

Holmes Air Purifier Technology

The many air cleaners designed by Holmes primarily use either HEPA (high efficiency particulate air) or HEPA-type filters, though many models also include ionizers that may be turned on or off separately from the filter. Despite the term “HEPA-type,” there is clearly a major difference between true HEPA filters and others. HEPA filters, including those used by Holmes, are much more effective. Holmes claims that its HEPA filters will remove 99.97% of all particles larger than 0.3 microns; whereas the HEPA-type filters will eliminate 99% of all particles larger than 2.0 microns.

A careless customer might only look at the percentages and suppose that they are about the same, but the distinction between 0.3 microns and 2.0 microns is considerable when dealing with indoor air pollution. Many common pollutants fall somewhere in between those two sizes, which means that a HEPA filter will eliminate them, but a HEPA-type filter will likely not.

Also, note that HEPA filters, HEPA-type filters, and ionizers will not effectively deal with gaseous pollutants, only solid particles.

Price Range of Air Purifier Models

Holmes’s air purifiers are easy to find and are some of the most affordable on the market. In addition, though, filters need replacing every six to twelve months, adding to the overall cost. One Holmes model, though, does have a permanent filter that does not need to be replaced.
