Whirlpool AP51030K Whispure Review
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.

  • Great pollen/dust/smoke clearing
  • Includes HEPA and carbon filters
  • Quiet
  • Costly replacement filters
  • Carbon prefilter works for light odors only
  • Air output can feel drafty

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 -- it also gets the nod as a Best Buy. 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. Owners concur, giving it very high ratings in thousands of reviews, and saying they have noticed a noticeable reduction in airborne particles, dust on their furniture, and in 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.


Decent ratings for low noise. In professional testing, the Whirlpool Whispure air purifier gets pretty good ratings for noise on both its high and low speed settings -- albeit slightly better for its low speed, as would be expected. It also receives praise from editors at AllergyBuyersClub.com for its quiet operation. Most owners concur, though some dissenting voices can be seen, as is common whenever youÕre looking at noise factors for any product.

Cost of ownership

Expensive replacement filters. The initial cost of this air purifier is less than that of premium air cleaners that it outperforms; however, replacement filters are expensive. This is one factor that keeps it out of making the cut as a choice at TheSweethome.com. John Holecek estimates its average filter costs as $106 per year. The Whispure's five-year warranty is good, and should offer some peace of mind for owners.

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.
