Air Purifier Reviews

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.

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.

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.

Rexair Company Info

Rexair LLC was founded in 1932 in Troy, Michigan, where it maintains headquarters to this day. Rexair has consistently sold just one product line through the years, the Rainbow Cleaning system. This series of home cleaning appliances uses the power of water sometimes combined with a HEPA filtration system for deep cleaning interior surfaces and improvement of indoor air quality. In 1959, the company developed a direct marketing strategy using independently distributors whose sales methods were focused on door-to-door tactics and home demonstrations.

Sales and Testing For the Rainbow System

Known as “The Rainbow Opportunity,” the Rexair company continues to use the direct-sale method of advertising and distribution for their Rainbow vacuum cleaners and recently introduced a line of Rainbow RainMate room air fresheners. Rexair is a member of the Direct Selling Association (DSA) and adheres to their policies of conduct and advertising.

Rexair’s Rainbow Cleaning System appliances have been tested by independent laboratories and received the Association of Home Appliance Manufacturers (AHAM) seal of approval and the Carpet Industry Standard (CRI) certification for removing three elements that affect carpets – soil removal, containment of dust particles and overall carpet appearance.

Trademarks and Brands

Rexair has registered trademarks for Rainbow, eSeries, e2, AquaMate, Hurricane and Rainbow Mate. They also sell cleaning products, fragrances and deodorizers that are designed to work specifically with their machines.

The Rainbow eSeries Vacuum combines a water bath filtration and HEPA Neutralizer filtration using a brushless process to trap dirt, dust, pollen and allergens, both from surfaces and from the air. The unit contains a water reservoir that can be emptied out, eliminating the need for vacuum cleaner bags.

Where To Find the Rainbow Products

Rexair products are not offered in any retail stores, only through direct marketing demonstrations and online independent dealerships. Some independent distributors have established their own local showrooms and repair shops to service the units they sell and have online marketplaces for supplies and replacement parts. The retail price of a Rainbow RainMate air purification system varies since they are priced according to whether or not they come with extra scent packages. Since there are no filters to replace, the only ongoing expense is the fragrance additions.

You have to contact the company directly for information about prices and distributors in your area either through their website at http://www.rainbowsystem.com/rainbowsystem/locator or you can call (248) 643-7222 during regular business hours (EST).

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.

Overview

Riccar Air Purifier Models

• Riccar FreshBreeze RAPL – The large Riccar FreshBreeze RAPL air purifier features a 5-stage room air cleaning system designed for a regular sized bedroom or office, about 280 square feet. Standing 21.9″ tall, 16.5″ wide and 9.9″ deep, this unit weighs 18.8 pounds and comes with a metallic silver plastic case. The filtration system includes a washable anti-bacterial cotton filter for trapping big particles, a washable nano-silver mesh/carbon filter to neutralize bacteria on contact, a HEPA filter that can capture 99.99% of the particles down to .3 microns, a charcoal filter to eliminate odors and a PlasmaWave electrostatic filter to neutralize odors, bacteria, viruses and chemical vapors.

The LED digital display has a timer that can be set for 1, 4 or 8 hours and includes a “sleep mode” for quiet nightime operation. The display panel includes a dust and odor sensor that allows you to automatically monitor the room’s indoor air quality and adjust the fan if needed. You can set this feature to run in automatic mode to instantly adjust to the level of impurities in the air. The control panel also has a light sensor that, when activated, automatically switches the unit to the lowest, quietest fan setting (and dims the display panel) when the room is dark.
• There is a CHANGE FILTER indicator on the control panel that will light up when it is time to replace the 3 non-washable filters, which come in a single cassette for easy changing. The filters have to be replaced around once a year, depending on usage. The washable filters should be cleaned every three months.
• Riccar FreshBreeze RAPM – The smaller Riccar FreshBreeze RAPM air purifier has the same 5-stage air cleaning system as the big model, as well as all the control features and a LED screen with remote. The metallic blue plastic model stands 18.5″ high, is 13.8″ wide and 9.1″ deep and weighs 13.7 lbs.
• Riccar EcoPure – Riccar’s EcoPure is a compact tabletop air filtration unit that uses a 3-stage process which includes a HEPA filter, an antimicrobial pre-filter and a carbon-deodorizing filter to freshen the air and to block particles down to .3 microns and capture 99.97% of the dust, mold and other contaminates from a small room.

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.

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.

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.

Ionic Pro Parent Company & Product History

The Ionic Pro® series is manufactured by Air Purifier, LLC, a member of the Electronic Retailing Association which specializes in direct-to-consumer commerce and is not associated with Sharper Image. Their line of five air purifiers can be purchased online or in stores such as Wal-mart, Best Buy and Frys.

This company suffered repercussions from poor ratings that ionic/electrostatic/ozonator technologies received from Consumer Reports for ineffective air cleaning and unacceptable ozone emissions. Their marketing strategy has centered on making their units significantly more affordable than the more effective air purification products by having them manufactured in China using reverse-engineered American designs.

Consumer Complaints

Many consumers choose an ionic air purifier because of its low price, quiet operation and the slight breeze that sends out a “clean” smell. They are easy to maintain since do not require filter changes, although the mechanisms must be serviced regularly, so the unit produces a “buzz” when it is time to clean the elements. The steel plate assembly can be wiped clean with a damp cloth and if the unit goes too long without servicing it will shut itself off to prevent creating a fire hazard.

Criticism of Ionic Pro products include false advertising regarding the nature of the filter, which is not a Pure HEPA filter and consequently does not capture particulates down to 0.3 microns. In fact, their “HEPA-type” filter only captures airborne matter down to 1 micron, which is comparable to the capture rate of a regular vacuum cleaner. Claims regarding coverage area is misleading, because much of that radius is a result of the ozone drifting away from the machine.

Clean Air Delivery Rate

A Clean Air Delivery Rate of approximately 20 is achieved when the positively-charged ionizer wire attracts electrified particles to the charged collection plate, known as the Zenion effect. Collector plates can be damaged by electrical fluctuations and replacements cost $30.00, so surge protectors are recommended.

Construction and Warranty

All the towers are made of plastic and available in black or white. A control panel on top of the tower has LED lights indicating the status and power setting of the unit. Warranties vary, and longer warranties are available for installment plan purchases.

Kenmore Company Info

The Kenmore line of appliances became associated with Sears since back in the late 1930s, and by 1936 over one million Kenmore appliances had been sold through Sears stores and mail-order catalogs. Over the decades, Kenmore has become their number one appliance brand, selling over 50% more than its closest competitor.

Kenmore Air Purifier Options

Out of the 5 air purification products offered by Kenmore, 4 are EnergyStar qualified for efficient operation, with the exception being the electrostatic model. They come in a range of coverage sizes from 150 square feet to 450 square feet and are competitively priced. All but one one unit has a true HEPA filter with a carbon filter with Sanitized® designed to remove smoke, dust and pollen. The units are advertised as having quiet motors, but no decibel figures are included in the product descriptions. All Kenmore air purifiers have a one year warranty.

Air Purification Technology

Kenmore’s HEPA filters are washable, but they still need to be replacedand replacement intervals are not mentioned in the product descriptions. The HEPA filtration systems capture 99.99% of the particulates in an air stream down to 0.3 microns. Room air quality is controlled by sensors that detect pollutants and automatically adjusts the fan speed for optimal cleaning. A blue LED “smooth touch” control panel is programmable.

Consumer Issues

Overall, the Kenmore line of air purifiers receives more bad reviews than good, many having to do with issues about getting repairs, receiving improper replacement parts and filters or about Sears policies and/or their customer service department. Some critics suspect that the units sold as Kenmore products are actually inferior knockoffs of brands like Sharp and Whirlpool.
