Alen BreatheSmart Air Purifier with Customizable Front Cover

by

The Alen BreatheSmart HEPA Air Purifier is built with a stylish and customizable design. I went with this item for the automatic feature, quality and lifetime warranty as it only cost $50 more out of pocket compared to the other brand after much consideration.

It’s a bit larger than appears in images but not too big that it’s a problem. It’s fairly quiet – you can’t hear it on the first settings and on turbo, it sounds like a fan running but is not as loud as my tower fans so I do not have to turn up the TV which is sits right next to.

I’ve noticed that having it near a ceiling air vent can drive it a bit crazy when the AC is on which you’d expect since dusty air is pouring out of the ducts. Sitting away from the vent, it changes settings less. The automatic feature is great as it will keep the air clean using the least of amount of energy.

I plugged this thing in after getting home from work this evening. I wasn’t expecting to notice anything from this. I always get violently ill for a couple days and then it turns into a heavily congested/clogged throat and nose which I’ve had for the past two weeks. After running this for 4 hours in my 700sf apartment, I noticed that my congestion started clearing up…20 minutes later it was gone. My nose and throat are completely clear..! I’m fairly sure it had to be a result of this air filter.

This thing is easy for setup, The BreatheSmart’s features smart sensor technology with intelligent sensor that consistently evaluates your environment in real time and will control the functions of the unit when the auto mode is engaged.

The sensor works perfect I can turn on the oven which is 17 feet away and sensor turns red. Burn some incense in the bed room which about 55 feet away turn red. When on medium and high it a little Noisy, on auto as soon as the air clears up it goes to blue and you can’t even here it. When I first got it I had on for four days straight.

Alen BreatheSmart is very quiet and powerful device. I really love of the technology in this device. The Smart Sensor is great. I love being able to quickly look at the device and see what the current air quality is. It’s very crazy to see how much the air quality drops whenever I cook something 2 rooms away. I didn’t realize the kitchen created that much of a drop in air quality. It’s a very nice and interesting feature.

These filters worked great. It was interesting to see its air quality indicator change colors when some event triggered bad air in the room. If the AC came on the filter knew, or if someone opened the door and smoke came in from the outside. It would turn red and start working harder.

It even knew when I started cooking, and considered this an event to turn red when it smelled food in the air. It has an ‘auto’ speed option so that when it detects bad air it speeds up. It has 4 speeds. You can choose a preferred speed manually, as well, if you want it to remain on one of them.

One of the things that surprised me was how quiet it was. On the lowest setting it is very, very quiet and is only noticeable on its higher settings. Having had a variety of other air filters, this one seems amazing in terms noise level.

It has a filter life indicator and a timer if you want it to run for 4, 8 or 12 hours. It has an ionizer function which produces ions without ozone. It also has a night or ‘lights off’ setting. When you first turn the power button to on, there are a number of indicator lights, as mentioned. If you want to run it in your bedroom at night with no lights, just press the power button again. To turn it completely off, press the power button a third time.

It has a number of different filters that can be ordered separately, or in some cases with the original machine. They range from the basic filter to one designed especially for molds/VOCs and others for smoke, etc.

BreatheSmart work beautifully with the look and feel of your space. It was very simple to put together. The lights are pretty and the plastic housing is very nice. It functions just as described and has made him feel so much better. The machine is a little loud for some. It takes up quite a bit of space compared to other purifiers I have had, which have all been towers.

The noise isn’t horrible and it’s just a blowing sound, not any obnoxious mechanical sound, but we do have to turn up the TV a few notches when watching a movie. The light on the top is cool, as it shows the level of cleanliness of the air. You can see it change to orange or red when the dogs come in the room. You can hear it kick in and know it’s going to take care of you. Overall a great product will make you feel a lot better!

 

Alen BreatheSmart HEPA Review

by

I am very impressed by the Alen Breathe Smart Air Purifier. I have always been allergic to cat dander and with the new air purifier the entire house is full of clean crisp air. We did not get the odor control filter but even the odors from our tenant cooking down stairs or residual smoke that would find its way into the house from smoking outside has cleared up.

This air purifier is wonderful. I love the automatic setting that will adjust to the level of impurities in the air. When cooking or cleaning litter boxes in the opposite side of the house the purifier will automatically bump up to red and go into overtime. I feel that it has made a huge difference in the air quality and I see a lot less dust particles in the air.

This unit is very quiet. I’ve got it right beside my bed and I’ve got to have silence in order for me to get to sleep. I’ve got it set to auto. It claims it senses particles in the air. It does change speeds on its own so there’s something to its claims. I have noticed the speed changes happen after I do something in the room that would stir up dust. With the unit on the room stays cooler as it circulates the air. Very expensive but I’d still recommend.

Within half an hour we could feel crispier, fresher air in our open living room floor that connects to the almost non-stop working kitchen. We moved the purifier to every room and ran it for about an hour/ each at the beginning. Now we just move it to our bedroom for the night since I have asthma and for the day we keep it in the living room. It’s really light for the size and its power so I have no problems carrying it myself (I’m a petit size 5’2) up and down the stairs.

I absolutely love it and recommend it to everybody having breathing problems. The price might be steep but on the other hand I save on medications because I don’t need them as often as before! And really, I’d rather inhale that “expensive” air than the steroids with gazillions side effects. Buy it!!!

Living in Manhattan NYC, we needed a high-powered air purifier for our apartment, one which would effectively clean the air of small and large particulates while being reasonably quiet and also aesthetically-pleasing in our living room.

The Alen BreatheSmart meets and exceeds all of our requirements. We have an expensive laser-driven air quality monitor and the Alen registers zero particulates in the exhaust airflow, which is perfect. The ability to manually switch the ionizer feature on and off is a real plus as well. We also have a Blue Air 403 (equally fabulous) as well as two Fellowes (AP-300PH & AeroMax 300) and an Alen T100. Our experience is that you get what you pay for in air purifiers. The Alen BreatheSmart is definitely worth the extra money. Highly recommend!

I turned it on turbo and let it run for a week straight to clean the air before turning it to auto which it stays on all the time now. It really does take all the “smells” out of the house. As soon as the door opens it kicks on high and gets to work immediately.

Before I turned it on I cleaned all the ceiling fans in the house to check the cleaning ability of the purifier and it has kept almost all of the dust from collecting around the house for 2 months now. Usually my wife has to dust at least 1 time a week, but this thing is amazing. The allergies in the house have dramatically been reduced and it really does cover the entire house very efficiently. I love this thing.

Alen BreatheSmart is very quiet and powerful device. I really love of the technology in this device. The Smart Sensor is great. I love being able to quickly look at the device and see what the current air quality is. It’s very crazy to see how much the air quality drops whenever I cook something 2 rooms away. I didn’t realize the kitchen created that much of a drop in air quality. It’s a very nice and interesting feature. I’m definitely happy so far.

The unit is light, for its size, and it is very accommodating with all the settings you can program. I keep it on automatic and it speeds up and slows down fan speed when detecting pollutants in the air. As I cook a lot I noticed when I am broiling or frying food when the odors from cooking reach the unit it detects them and speeds up.

This unit seems to do what it claims though I was somewhat reluctant to pay the price of admission. But in just a couple of day’s use of the BreatheSmart, my wife’s eyes have stopped itching when she wakes up in the morning. And my stuffy nose and breathing have improved. This is a solidly built, sizable machine; its quiet mode is quieter than any other air processing machine that we have ever owned. In the final analysis, healthier lung function and reduced allergies, along with reduced use of pharmaceuticals, is why we bought this unit, and better health is worth paying for.

We were suffering from the fire situation on the west coast and needed something to help fast. My spouse has COPD and my dog has bronchitis. Both were in bad shape this summer, but these filters worked great.

It was interesting to see its air quality indicator change colors when some event triggered bad air in the room. If the AC came on the filter knew, or if someone opened the door and smoke came in from the outside. It would turn red and start working harder. It even knew when I started cooking, and considered this an event to turn red when it smelled food in the air.

It has an ‘auto’ speed option so that when it detects bad air it speeds up. It has 4 speeds. You can choose a preferred speed manually, as well, if you want it to remain on one of them.

It has a filter life indicator and a timer if you want it to run for 4, 8 or 12 hours. It has an ionizer function which produces ions without ozone.

It also has a night or ‘lights off’ setting. When you first turn the power button to on, there are a number of indicator lights, as mentioned. If you want to run it in your bedroom at night with no lights, just press the power button again. To turn it completely off, press the power button a third time.

It has a number of different filters that can be ordered separately, or in some cases with the original machine. They range from the basic filter to one designed especially for molds/VOCs and others for smoke, etc.

One of the things that surprised me was how quiet it was. On the lowest setting it is very, very quiet and is only noticeable on its higher settings. Having had a variety of other air filters, this one seems amazing in terms noise level. We liked this first one so much we bought two more. Now our indoor air is incredibly clean and the family is breathing fine.

Sun Pure Air Purifiers Guide

by

Ultra-Sun Technologies Company Info

Ultra-Sun Technologies is a California based company that has been manufacturing air purifiers under the brand name SunPure for an unknown period of time. Their air purifiers sell for anywhere from $500-$995 depending on the retailer.

Sun Pure Air Purifier Technology

The SunPure Model SP-20’s have a six step filtration system. When air is sucked into one of these air purifiers, the first filter it encounters is the pre-filter. This filter traps particles that are larger than five microns. The advantage to having a pre-filter is that it helps extend the life of the HEPA filter by making sure it doesn’t have to deal with large particles, thus allowing the filter more room to capture more small particles.

The second step in this system is a specially formulated gas absorption media. This filter removes exhaust fumes, hydrocarbons, formaldehyde, pesticides, paint solvents, chlorine, cleaning chemicals and other nasty and potentially dangerous fumes and odors from the air. The third filter is a carbon filter that focuses exclusively on removing odors from the air such cooking odors, the stink of pets, and air conditioning systems. The carbon filter can also get rid of low level ozone.

The HEPA filter is the fourth filter. It is a hospital grade filter that can remove particles so small they can only be seen through a microscope. The air then goes through the fifth step, an ultraviolet light. This light is 10,000 times the intensity of real sunlight. It is designed to kill bacteria and viruses. The sixth and final step is negative ionization. In the process of negative ionization, a molecule called an ion receives an extra electron, resulting in the ion becoming negatively charged. A negatively charged ion tends to stick to things, so when it comes in contact with a particle floating in the air, it sticks to it and traps it in the air purifier.

The Model SP-200 only uses three steps in its system. The first filter is an electrostatic MER-11 filter that removes particles such as pollen, mold, dust mites, smoke and bacteria from the air using static electricity. The second step uses a photo-catalytic oxidation process to convert toxic fumes into benign ones. The third step is an ultraviolet light that kills bacteria and viruses.

The Model BAT air purifiers are designed to specifically focus on mold and germ reduction. To this end, these purifiers have ultraviolet lights to kill bacteria and germs along with titanium dioxide filters that promote a photo-catalytic oxidation process to eliminate toxic fumes and other problematic air pollutants. The titanium dioxide filters can get rid of volatile organic compounds (VOCs) as well as odors and deadly carbon monoxide.

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.

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.

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.

Vornado Air Purifiers Guide

by

Vornado Company Info

Vornado is a manufacturer of air purifiers, humidifiers, heaters, and personal circulators. These fans became popular very quickly due to their performance and power. These early Vornado’s propelled them as a company that would become known for product durability and innovative technology.

Vornado Air Circulation Technology

Throughout the 1940’s and beyond, Vornado was known as a company on the cutting edge of the the air purifying and cooling industry. In Andover, Kansas, in 1989, a new Vornado company was founded and created what was known as the first “whole room circulator”. The performance of a Vornado product is enhanced by the signature vortex action that is a feature of their products. These four proprietary components are only found in the technology presented by Vornado.

Unlike other fans and heaters, Vornado’s Vortex Action enables the air to be distributed equally through the room and not just around the air of the unit. It was soon found that this same Vortex Action could be applied to other products, which is what has propelled the Vornado’s Whole Room Air Purifiers to being recognized in the industry. Due to the the highly efficient design and unique technology, Vornado air purifiers still have a strong reputation in the industry today.

Consumer and Critical Acclaim

Vornado strives to continue producing innovative products that are more effective and intuitive as well as safer and quieter than anyone else in the industry. The air flow products that they produce present a quality and durability that seems to be appreciated by consumers. Their reputation is backed by their former model, the AQS35, receiving high rankings from Consumer Reports, Amazon.com, and epinions.com. The new AQS 500 is currently available for around $100.

Clean Air Delivery Rate Certified

Vornado air purifiers are certified by AHAM, the Association of Home Appliance Manufacturers. This organization is responsible for certifying testing results of certain household products, such as air purifiers, dehumidifiers, and air room conditioners. This seal can be found on many appliances and is a good indicator of a reliable, quality product. The certified rating given to air purifiers is known as CADR, or Clean Air Delivery Rate. The three CADR numbers refer to the amount of smoke, dust and pollen being filtered out of the air.

Westinghouse Air Purifiers Guide

by

Westinghouse offers a indoor air quality equipment that can be installed on new or existing HVAC systems as well as a line of portable air purification units for different sized rooms. These units are designed to target indoor air pollutants such as mold, dust, pollen, chemicals, pet dander and tobacco smoke.

Portable Indoor Air Purifiers

Westinghouse produces three portable air filtration units that are ideal for single rooms, workshops and offices. They boast a “whisper-quiet technology” and the unit itself occupies very little space. Contaminated air passes through a pre-filter, a HEPA filter, a carbon filter, a bacterial prevention filter and a complex silicon filter that absorbs kitchen odors.

HVAC Whole House Air Cleaners

Westinghouse makes a line of indoor air quality products designed to be attached directly to the HVAC units in commercial and residential properties. They can be installed either as a retrofit or as part of a new energy-efficient home unit.

Westinghouse’s Dual Air Cleaning system uses a HEPA filter to clean the dirty air as it enters the HVAC unit from the main vents. This filtered air is deflected into an Electrostatic Media Air Cleaner which removes additional airborne pollutants. By that time the air enters the furnace or air handler, it has had 99.9% of particulates down to 0.3 microns in size removed from the air stream. This greatly enhances the performance and lifetime of the HVAC unit while providing clean air to the entire house — which prevents a buildup of mold and mildew — and many other airborne contaminants that trigger respiratory issues and cause deterioration of structures.

The Westinghouse In-Duct Air Purifier uses the Sanuvox High Efficiency UV system which has a “Turbulator” to slow the air as it moves over a UV “J” Lamp. This dramatically increases the ultra violet lights’ ability to kill harmful contaminants in the airstream. They are installed inside HVAC ducts and activated when the ventilation fan switches on, although they are designed to run 24 hours a day. The only maintenance required is replacing the lamp.

Whirlpool Air Purifiers Guide

by

Whirlpool Air Purifier Technology

Whirlpool has three separate models of air purifiers to accommodate different sized rooms. All of the units contain a carbon pre-filter and a True HEPA filter that captures particulates down to 0.3 microns and removes 99.97% of the airborne particulates. All of the Whirlpool air purification units have a basic exchange rate of 4.8 times per hour, and the largest model has a turbo feature for quicker air purification. T

he double filtration system will remove airborne allergies such as dust, pollen, mold spores, pet dander, fabric fibers and tobacco smoke. All units carry a 30-day Money Back Quiet Guarantee and a 5 year limited warranty — with a four year guarantee against engine burn out — and are ENERGY STAR® qualified.

Replacement Filters

Whirlpool air purifiers and replacement filters are sold by Master Brands HK LTD, who is licensed to distribute their products. Whirlpool uses the 3M Filtrete True HEPA® filter that requires a yearly replacement, which costs from $80.00 to $100 per filter depending on the size of the model. The charcoal pre-filters have to be replaced four times a year, and are typically sold in packs of four and cost $28.00 to $39.00 a package.

In 2009, there was a production gap and the medium-sized air purifier model — the Whispure 450 Series –was discontinued due to slow sales because many builders dropped it from their inventory. This model was reintroduced in 2010 by popular demand.

Consumer Reports Ratings

Whirlpool air purifiers have received top ratings on Consumer Reports reviews and ranks just below the higher priced models like the Blueair 501 or 601 or the Kenmore 85264. In 2005, Whirlpool was rated the second most popular air filter out of 30, and was featured as a best “quickie” recommendation. The fan is run by a Quiet Partner® System that ranks 8 out of 10 for noise level, with complaints about the some speeds being too loud for normal conversation.

Consumer Complaints

Criticisms of the Whirlpool air purification models include ineffective odor removal since the carbon filter is not highly ranked for VOC purification. Complaints about the frequency of filter changes are common. They are not effective against MCS or chemical contamination and do not produce ozone. It has also been noted that cigarette smoking fouls the pre-filter quickly. But overall, Whirlpool models score an 8 out of 10 ranking for customer reviews, and Whirlpool claims that their units have been ranked number one by consumers as the preferred brand for their category, although they don’t give specific references.

Why Indoor Air is More Polluted Than Outdoor Air?

by

EPA Warns About Air Quality In Your Home

It’s the third straight day in a heat spell, with the mercury soaring into the 80s and 90s. The weatherman reports that there’s no relief in sight, noting further that the low pressure front responsible for the temperature spike is also keeping the pollutants from automobiles suspended overhead in a dull brown haze. The air quality index is bad, he tells you. The Environmental Protection Agency (EPA) is urging citizens, whenever possible, to work from home; and further cautioning individuals with asthma or other reactive airway conditions to avoid breathing the toxic air.

When you hear a warning like this, understandably you feel anxious. But did you know that the Environmental Protection Agency has issued similar warnings about the inside of your own home? You may be surprised to learn that much of the time, the air inside your own home can be even more polluted and hazardous to your health than the air outside.

Who’s at risk? People who spend the most time inside their homes, which is to say the very young, the very old, the chronically ill – and their caretakers. Researchers say these individuals may spend as much as 90% of their time indoors. But the rest of us, who spend anywhere between 65% and 90% of our time in our homes, are also at risk.

Sources of Indoor Air Pollution

Lack of Ventilation

What’s the ventilation like inside your home? If you live in those parts of the United States affected by winter, chances are your home is winter-proofed. While insulating, sealing and caulking your home may keep out the chill, these techniques can also make your home so airtight there’s no way indoor dust, tobacco smoke, other combustion products or other pollutants can diffuse into the outer air. That means they stay trapped inside your home – where you inhale them at the risk of your health.

In order to maintain circulation, you will need to increase the amount of outside air coming into your home. Open windows and doors when weather permits. Run exhaust fans in your kitchen and bathroom with outside ventilation system. Make sure all gas appliances like stoves, dryers and water heaters have vents going to the outside, and in the summer time, run your air conditioner with the vent open.

Painting a room? Open a window if you can and make sure the overhead fan is on. It’s particularly important to observe precautions designed to minimize exposure to pollutants any time you use paint, cleaning solutions, pesticides or solvents containing potentially harmful chemicals.

Dust & Dust Mites

The main source of indoor pollution is common dust. For every six rooms in your house (approximately 1,500 square feet), approximately 40 pounds of dust is generated in a single year. Dust is an accumulation of textile fibers from upholstery, drapes, pillows, linens and other furnishings in your home, as well as flakes of human skin, pet dander, animal hair, insects, food particles, pollen, mold spores, insulation – and dust mites.

For every six rooms in your house (approximately 1,500 square feet), approximately 40 pounds of dust is generated in a single year

You may prefer to think of dust particulate as inanimate – but it’s not. It’s home to a veritable plantation of microorganisms including bacteria, viruses and Dermatophagoides pteronyssinus and Dermatophagoides farinae, also known as the common dust mite. It’s been estimated a single gram of dust contains 100 to 500 mites. Dust mites don’t bite, nor do they spread disease, but people with reactive airway diseases are often severely allergic to their droppings.

Dust collects on surfaces, so it stands to reason that the fewer surfaces you have in your house – the fewer knickknacks, books, tables piled high with magazines you haven’t yet gotten around to reading – the less dust you will accumulate. Remove as many dust-collecting items from your house as possible. A vacuum cleaner can actually contribute to your dust problem unless it’s the high efficiency filtering model. Dust mites thrive in moist conditions so be sure get rid of any excess moisture or water in your home. If you use a humidifier, be sure to fill it with fresh water daily, and clean it often according to the manufacturer’s instructions.

Tobacco Smoke

Tobacco smoke is a known carcinogen, as well as a primary factor in the development of chronic obstructive pulmonary diseases. A number of studies have also conclusively linked tobacco smoke to heart disease.

Secondhand tobacco smoke is a combination of the smoke given off by the burning end of a cigarette or a cigar, and the fumes exhaled by smokers. It is particularly dangerous to children whose lungs are immature and still developing, and whose respiratory rates are higher than that of adults. Babies exposed to secondhand smoke have a higher incidence of Sudden Infant Death Syndrome (SIDS). Children exposed to secondhand smoke stand a greater chance of developing asthma (even if they’ve never before exhibited symptoms), suffer from ear infections and develop pulmonary complications like pneumonia and bronchitis. Elderly people exposed to secondhand smoke are at increased risk of developing dementia.

How do you control the harmful effects of tobacco smoke? Stop smoking yourself, and never let anyone smoke within your home or in your car.

Stoves, Heaters, Fireplaces, and Chimneys

Tobacco smoke is not the only product of combustion that may be hazardous to your health. Wood stoves, fireplaces, gas stoves, kerosene and gas space heaters can be sources of carbon monoxide and nitrogen dioxide gas, as well as particulate matter that can lodge in your lungs, causing damage.

A persistent, yellow-tipped flame is generally the sign of a malfunctioning kerosene or gas space heater, and is a warning that pollutants are being produced: when the equipment is operating correctly, its flame is blue. Make sure that you’re using the proper fuels and adjusting the heater according to the manufacturer’s directions. Never close the door to a room in which you are operating a space heater; weather permitting, always open the window a crack.

When using a wood stove, make sure that the door is fitted and use cured (dry) wood. Stove hoods with fans venting to the outside reduces your exposure to potentially harmful substances while you are cooking.

Volatile Organic and Inorganic Compounds

Paints, solvents, clothes just back from the cleaners, air fresheners, aerosol sprays can all be sources of pollution from organic compounds.

Formaldehyde, a preservative and bonding agent, is commonly found in particle board and pressed wood furniture. Symptoms of formaldehyde exposure may include watering eyes, nausea and difficulty breathing that manifests as a burning or choking sensation in the throat. To reduce exposure, make sure to ask about the formaldehyde content of any new pressed wood furniture you’re thinking of purchasing, and buy “exterior-grade” particle board whenever possible: exterior-grade pressed wood products contain phenol resins in place of more toxic urea resins.

Radon

Radon is a colorless, odorless, radioactive gas, implicated in 21,000 deaths from lung cancer a year according to the EPA. Radon comes from the natural breakdown of small amounts of uranium in water, soil and rock. Radon easily infiltrates building structures. Do-it-yourself radon tests are sold in hardware stores to help people determine whether their homes have been exposed to radon. Professional radon testing is often part of the process of vetting a home that’s been put up for sale. If you smoke and your home is positive for radon, you stand an increased risk of developing lung cancer.

The most effective way of ridding a home of radon is through the use of a soil suction radon reduction system consisting of a vent pipe system and a fan; this is designed to pull radon from the atmosphere inside the home and vent it to the outside. Repairing cracks in your home’s foundation is also highly recommended.

Indoor Pollution: Tips For Apartment Dwellers

Indoor pollution can be just as much of a problem for people who live in apartments as it is for people who live in homes. In most instances, the same preventive steps that allow home dwellers to reduce harmful exposure will also work for apartment dwellers.

In some instances, however – for example, testing for potential radon exposure – an apartment dweller will have to enlist the aid and support of his or her landlord or apartment manager.

Winix Air Purifiers Guide

by

Winix Company Info

Winix Air Purifiers are manufactured and sold by the Winix Corporation. Started in 1973 and settling on the Winix name in 2000, their head office is located in Shiheung City, a suburb of Seoul, South Korea. The company owns manufacturing factories in Korea, Thailand and China. Winix produces a wide range of home environmental appliances, including air purifiers, air coolers and cleaners, dehumidifiers, fan heaters, cold and hot water purifiers, water dispensers, air conditioner components, evaporators, condensers, bidets and others; however their air purifiers are the only products exported to the United States. Some of their products are also exported to Japan.

Winix’s United States offices are located in East Dundee, Illinois which is about an hour from downtown Chicago, which handles all North American sales and warranties. They are partnered with a large number of US retailers, including The Home Depot, Sears, Walgreen’s, Target, Best Buy, Costco, Fry’s, and Hammacher Schlemmer, among others.

Air Purifier History

Winix has been making air purifiers since at least 2003 and exporting them to the US from around 2006. They have built up the reputation of their air purifiers to the point that they are highly regarded by many reviewers. Although not excellent, more than one reviewer of their PlasmaWave line of air purifiers have commented that, comparing the features to the price, Winix offers a good value in their product, especially their higher end products.

Awards and Recognition

According to the English language version of their Korean corporate website, Winix has been awarded with a number of awards in Korea, although it is a little unclear what products those awards are for. Some of the awards are for simply being a large successful company while the majority of their company history discusses their growth in foreign markets.

Winix Air Purifier Technology

For their top three models, Winix uses a 5 stage cleaning method, while their base model, the 5000B uses a 3 stage cleaning method. Their claimed cleaning efficiency is 99% for the 5000B and 99.7% for their lowest level 5-stage air purifier or 99.9% for their two top models. The 5 stage models use the following steps: washable anti-bacterial pre-filter, true HEPA filter, nano-silver mesh, washable carbon filter, followed by their final step, the PlasmaWave Technology, which is their biggest selling point and the namesake of their product line. It claims to generate both negatively and positively charged ions that, combining with water vapor in the air and form Hydroxyls.

These Hydroxyls, according to Winix literature, instantly neutralize viruses, bacteria, chemical vapors, odors and gasses in the air. This technology is the basis for Winix’s claims to silently remove from the air pollen, mold, smoke, dust and pet dander, while at the same time, neutralizing flu viruses, odors and bacteria. Their lower end model, the 5000B 3-stage air purifier, has only the carbon pre-filter, true HEPA filter and the PlasmaWave Technology.

Replacement Filters

While few of these claims have yet to be verified, such as the neutralization of flu viruses, Winix air purifiers do consistently receive high praise from reviewers and customers. The one point of contention seems to be the price of the replaceable filter. They typically run around 100 bucks and Winix recommends they be replaced every year or so with regular use.

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.

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.

Hamilton Beach Air Purifier Models

Sharp Air Purifiers Guide

by

Sharp Company Info

Sharp Corporation’s business creed is “sincerity and creativity”, and the companies making up the Sharp empire generally succeed in living up to this ideology.

The small manufacturing business owned by Tokuji Hayakawa that would eventually become today’s multi-national Sharp Corporation – named after their iconic product, the “Ever-Ready Sharp Pencil” – began life in Japan in September 1912. Hayakawa incorporated in 1935, and his business became known as Hayakawa Metal Works Institute Co. Hayakawa’s – soon Sharp’s – energetic marketing and innovative engineering quickly combined with their products’ universal appeal to make Sharp a leader in the manufacture and sale of industrial, corporate and household electronics.

Sharp branched out into the design, manufacture and sale of air purifiers during 2000 and soon introduced their Plasmacluster ion air purification technology to the public. Sharp claims that the Plasmacluster system is a world first as it “deactivates” airborne impurities by emitting both positive and negative ions. Sharp’s advances in the air purification field have been recognized by several international institutions, and the company has been awarded both the Japanese Takagi Award and the British Allergy Foundation Seal of Approval.

Sold As “Sharp” or “Sharp-Roxy”

Sharp Corporation, which is headquartered in Osaka, Japan, comprises 13 separate Japanese companies, 44 consolidated overseas companies and 12 unconsolidated overseas companies. Not all companies are, however, involved in direct-to-public sales, and some concentrate on research and development. Air purifiers are, furthermore, not sold through all of Sharp’s manufacturing/sale outlets but are offered for sale by at least 23 of them. All air purifiers are sold under the “Sharp” brand, except for those available in Singapore, Hong Kong and Malaysia, which are sold under the “Sharp-Roxy” brand.

Air Purifier Price Range

The purifiers sold by the Sharp companies are listed below, with the companies in roughly the same order as found on the Sharp Corporation website.
