Yes — HEPA air purifiers are proven to capture 99.97% of airborne particles 0.3 microns and larger, including dust, pollen, mold spores, and many bacteria. Studies show they reduce indoor particulate matter significantly, which can benefit allergy sufferers and those with respiratory conditions. The key is choosing the right size for your room and replacing filters on schedule.
Match the purifier's CADR (Clean Air Delivery Rate) to your room size. A general rule: the CADR should be at least two-thirds of the room's square footage. For a 300 sq ft bedroom, you need a CADR of at least 200. For whole-room coverage, check the manufacturer's recommended room size and err on the larger side.

HEPA filters typically need replacement every 6 to 12 months, depending on usage and air quality. Carbon/activated charcoal filters for odors last 3 to 6 months. Some models have filter life indicators. Running the purifier 24/7 in high-pollution areas shortens filter life. Budget $30 to $80 per year for replacement filters.
