The Whirlpool AP51030K features a three-stage filtration system comprised of a pre-filter, carbon filter, and true HEPA filter. The air purifier's outside grill acts as a permanent pre-filter by capturing large particles and preventing them from entering the unit. Large particles that find their way inside the unit are promptly caught by the carbon filter, which also works to eliminate unwanted odors and protect the life of the HEPA filter. At the heart of the Whirlpool Whispure 510 is true HEPA filtration. HEPA filters provide maximum filtration of your room's air by removing up to 99.97% of particles that are 0.3 microns and larger. These particles include pet dander, dust mites, pollen, ragweed, mold spores, and other microscopic irritants that can damage your indoor air quality and aggravate allergy and asthma symptoms. This kits comes with Genuine Whirlpool 817143K large carbon Pre-Filters (4 Pack), and Genuine Whirlpool 1183054K HEPA Filter.
