What to look for in an air purifier

Room size & CADR. Match the Clean Air Delivery Rate (and rated coverage area) to your room’s square footage so it actually cycles the air several times an hour.
True HEPA filtration. An H13 True HEPA filter captures 99.97% of fine particles. An activated-carbon layer is what tackles odors and smoke.
Noise. For bedrooms, check the decibel rating and look for a quiet sleep mode.
Filter cost. Replacement filters are the real long-term cost — check the price and how often they’re needed before buying.
Smart features. An air-quality sensor with auto mode ramps the fan only when needed, saving noise and filter life.

Frequently asked questions

Do air purifiers really work?

Yes — a properly sized True HEPA purifier measurably reduces airborne dust, pollen, and smoke particles in a closed room.

HEPA or ionizer?

True HEPA is the proven standard. Be cautious with ozone-generating ionizers; HEPA plus carbon is the safe, effective combo.

Should I run it all day?

For best results, yes — ideally on auto mode, which speeds up only when air quality drops, keeping noise and filter use low.

How often do I replace the filter?

Typically every 6–12 months depending on use and air quality. Many models have a filter-life indicator.
