How many air purifiers do I need?
One per room where you spend the most time. For most people, that’s the bedroom and living room.
Why does my house get so dusty?
Common causes: poor HVAC filtration, open windows, pet dander, dead skin cells, and outdoor dust infiltration. An air purifier addresses the airborne portion.
