HEPA Air Purifier

HEPA (High-Efficiency Particulate Air) filters capture 99.97% of particles ≥0.3 microns — dust, pollen, pet dander, mould spores
PM2.5 (fine particulate matter) penetrates deep into lungs and enters the bloodstream — HEPA removes it
VOCs from paints, cleaning products, and furniture require an activated carbon filter in addition to HEPA
Run continuously in the bedroom — sleep is 8 hours of uninterrupted air exposure
CADR (Clean Air Delivery Rate) should exceed 2/3 of the room's square footage in cubic feet per minute
