Levoit Vital 100S-P vs Winix 5520

For a bedroom, the Levoit Vital 100S-P, since it is the lower priced of the two, adds Bluetooth setup and a numeric screen, and is certified ozone-free. The Winix 5520 is the better purifier for a larger room, where its AHAM Verifide 253 CFM rating for 392 sq ft and certified True HEPA filter come into play.

Coverage and filter certification. The Winix 5520 is AHAM Verifide at 253 CFM for 392 sq ft with a certified True HEPA filter, while the Levoit Vital 100S-P is rated for 222 sq ft at 143 CFM and uses a filter Levoit calls HEPA-grade in Sleep Mode.

Only the Levoit Vital 100S-P. It filters mechanically and is certified ozone-free and Energy Star. The Winix 5520 includes a PlasmaWave ionizer stage, so it is not listed as ozone-free and carries no Energy Star certification.

Both work with Alexa through their own apps, and both reach Home Assistant, the Levoit Vital 100S-P through the official VeSync integration and the Winix 5520 through a community one. Google Home is documented for the Levoit but not confirmed for the Winix, and neither supports Apple Home, SmartThings or Matter.

Plan around 222 sq ft, which is Levoit's figure at 4.8 air changes per hour and is backed by its 143 CFM CADR. Levoit also prints a much larger number at a single air change per hour, but that is not enough to keep a room clean.

A buyer who needs a larger room covered and wants an AHAM Verifide figure with a certified True HEPA filter and a washable pre-filter, and who is not concerned about the PlasmaWave ionizer stage.
