How to choose
HEPA filters and coverage
A HEPA filter traps fine particles, and coverage tells how large a room the maker rates the unit for. The LEVOIT coverage is rated for up to 1,073 sq ft by the maker, the Purivortex purifies rooms up to 880 ft² in one hour, and the KNKA coverage is rated for up to 1,695 sq ft by the maker. Match the rated coverage to the room, not to the whole home, and check the filter stages for each pick.
Noise levels and fan speeds
The rated noise level tells how loud the unit runs on a low setting, and fan speeds set how much air moves. The LEVOIT Sleep Mode quiets fan speeds to as low as 25 dB, the Purivortex is rated at 20 dB, and the KNKA Sleep Mode runs at 22 to 24 dB. The Purivortex and the KNKA each have 4 fan speeds. Pick a low rated noise level for a bedroom, and check the speed count for daytime use.
Upkeep and replacement filters
A washable pre-filter rinses with water, and a replacement indicator tells when the main filter needs a change. The LEVOIT pre-filter rinses with water, and the KNKA pre-filter is washable with a filter replacement indicator. The KNKA filters need replacement every 3 to 6 months. Check the filter type and the replacement interval before you buy, and use the filters made for the unit.
