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.
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.
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.
