What can a HEPA air purifier remove?
A true HEPA filter mechanically captures airborne particles — dust, pollen, pet dander, mold spores, smoke particles (PM2.5), and dust-mite debris. A HEPA 14 filter like the AirPro’s captures 99.995% of particles at 0.3 microns, the hardest size to trap, and 99.9% down to 0.1 microns. That is a real, measurable reduction in airborne particulate, which is why HEPA is used in hospitals and cleanrooms.What about odors, smoke, and chemicals?
Particles are only part of indoor air. Activated carbon adsorbs many odors and volatile organic compounds (VOCs) — cooking smells, smoke odor, and some off-gassing — which is why the AirPro pairs carbon with its HEPA stage. See VOCs and formaldehyde. Carbon helps with gases and odors that HEPA alone cannot trap.What can’t an air purifier do?
This is where expectations matter. A filter-based purifier cannot:- Remove gases like radon or carbon monoxide (you need dedicated detectors)
- Lower CO2 or fix a “stuffy” room — that requires ventilation
- Remove allergens already settled in carpet, bedding, or on surfaces
- Replace cleaning, pest control, or fixing a moisture/mold source
How do I know it’s working?
The AirPro has no air-quality screen, so judge it by results over days to weeks: fewer odors, less settled dust, and easier breathing for allergy sufferers. Its smart tracker tells you when to change the filter. For best results, run it continuously with clearance around the 360-degree intake.How do I get the most benefit?
- Size the unit to the room — see CADR, ACH, and room size.
- Run it 24/7 rather than in short bursts.
- Keep windows closed on high-pollen, smoke, or smog days.
- Replace the filter on schedule (every 6–12 months).
An air purifier is a helpful tool for cleaner indoor air, but it is not a medical device or a cure for allergies or asthma. Use it alongside — not instead of — any treatment your doctor recommends. See air purifiers for asthma.
