The Whirlpool AP51030K Whispure air purifier is a solid performer that costs less up front than some premium air cleaners, although its costly replacement filters add to the cost of ownership over time. 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.
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. 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 and Epinions.com concur, noting that the Whirlpool AP51030K Whispure noticeably reduces dust particles in rooms and eliminates allergy and asthma symptoms.
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 to sites like Amazon.com and Epinions.com say the controls are easy to use and appreciate the various options for fan speed, which aids in noise control.
Quieter than most, even on highest setting. This 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. One owner posting feedback to Amazon.com says, "On the lowest setting I can watch TV at normal volume levels with the unit sitting three feet from me. After leaving the room it's easy to ratchet it up to the turbo mode which I leave it on most of the time when not using in the living areas."
Expensive replacement filters. The initial cost of this air purifier is less than that of premium air cleaners. However, with replacement filters costing $100 per year, the Whirlpool quickly winds up costing more than air purifiers that offer lifetime filters. One owner posting to Amazon.com also complains that the unit generates heat during use, which will end up costing you more in air-conditioning expenses. The Whispure's five-year warranty offers peace of mind for owners.

Review: Air Purifiers, Editors of ConsumerReports.org, April 2012
Experts at AllergyBuyersClub.com say the Whirlpool AP51030K reduces room particles during testing and that it's quiet even on its turbo setting. They do note that its charcoal filter isn't strong enough to tackle big odors or volatile organic compounds (VOCs), and that the foam silencing insulation may aggravate chemically sensitive people.
