How to choose
Match rated coverage to the room
Compare that figure with the floor area you need covered: the HEAPETS pick is rated for up to 2,500 sq ft by the maker, the BLUEAIR pick for up to 2,107 sq ft, the PAKEOI pick for up to 3,000 sq ft and the COWAY pick for up to 3,120 sq ft. Pick a rating that covers the full area rather than part of it.
CADR, fan speeds and noise
CADR measures airflow in cubic feet per minute, so it describes how much air moves through the purifier. The HEAPETS pick has a CADR of 176 CFM. Fan speeds set how hard the unit runs: the HEAPETS pick has 5 speeds and the PAKEOI pick has 4 speeds. Noise figures describe sound output: Sleep Mode runs at 25 dB on the HEAPETS pick and at 15 dB on the PAKEOI pick, while the BLUEAIR pick runs from 23 to 50 dB.
Filters, upkeep and placement
A pre-filter catches larger particles before the main filter, and a washable pre-filter can be rinsed and reused. The HEAPETS, BLUEAIR, PAKEOI and COWAY picks each have a washable pre-filter. Check the replacement interval for the main filter: the PAKEOI pick recommends a new HEPA filter every 6 to 8 months, and the HEAPETS pick has a filter replacement reminder. Keep air inlets unobstructed so air keeps flowing.
