Smart
Check price
For bedrooms where you want to see the air quality, not guess. Built-in particulate and humidity sensors with an auto mode that ramps with the room. HEPA handles fine particles down to PM1. The catch: no carbon stage, so it does little for odors or gases.

Premium
Check price
If you deal with smoke, chemicals, or strong odors, this is the heavy hitter. Medical-grade HEPA plus 15 lbs of activated carbon and zeolite, rated for rooms up to 1500 sq ft, with filters that last about 5 years. You pay for it in price and weight.

Filterless
Check price
A filterless purifier that heats incoming air to destroy mold, bacteria, and dust mites, so there is nothing to replace and no filter cost. The tradeoff is real: it does not capture dust or large allergens the way a HEPA unit does, so pair it with one if particles are your problem.

Specialty
Check price
A floor vacuum and air purifier in one, made for entryways and pet areas. Sweep debris to the touchless sensor base and it pulls it in, while the HEPA side handles airborne dust. As a pure air purifier, a dedicated HEPA unit moves more air for the money.
