Bottom line

The Whirlpool AP51030K Whispure air purifier is a solid performer that costs less up front than some premium air cleaners, although it's less effective than some in clearing odors or chemicals from the air. But when it comes to particle removal, the Whispure is top-rated in professional reviews and gets excellent ratings from owners, who say there's a noticeable difference in air quality and a reduction in allergy symptoms. Another plus is that the electronic controls make it a cinch to use.

Breaking it down


Noticeable improvement in air quality. The Whirlpool AP51030K Whispure air purifier gets top marks in one major test, where it exceeds expectations for filtering dust, pollen and cigarette smoke out of the air on high and low fan speeds. Ed Sherbenou of Air-Purifier-Power.com isn't impressed by its effectiveness at getting rid of odors or chemicals, but does say that it is "a good choice for seasonal pollen, housedust, or mold allergy sufferers." Editors at AllergyBuyersClub.com say the Whispure "significantly reduced the particle count in the room" and note its "impressive" ability to clean large rooms considering the size of the unit. Hundreds of owners contributing to sites like Amazon.com concur, noting that the Whirlpool AP51030K Whispure noticeably reduces dust particles in rooms and eliminates allergy and asthma symptoms.

Ease of use

Intuitive electronic controls. The Whirlpool Whispure is easy to use, with electronic controls and a "nicely-labeled" dashboard, according to editors at AllergyBuyersClub.com. Editors also point out the convenience of the five-stage filter status indicator, noting that it lets you know when the filter is reaching the end of its life in ample time to order or purchase a replacement. Owners posting feedback at user review sites say the controls are simple to use and appreciate the various options for fan speed, which aids in noise control.


Quieter than most, even on highest setting. This Whirlpool air purifier is quieter than other air cleaners on both its high and low settings; it was the quietest portable air conditioner tested in one expert test and receives praise from editors at AllergyBuyersClub.com for its quiet operation. Most user reviews concur, though some dissenting voices can be seen at Amazon.com

Cost of ownership

Expensive replacement filters. The initial cost of this air purifier is less than that of premium air cleaners. However, replacement filters are expensive and can wind up costing as much as half of the original purchase price per year, Sherbenou says. The Whispure's five-year warranty is good, and should offer some peace of mind for owners.
