HEPA, CADR, and MERV in plain English

HEPA usually matters for portable room air purifiers because it targets small airborne particles like dust, pollen, and dander.

CADR helps you match a purifier to the size of your room. A higher CADR can serve a larger space or clean air faster.

MERV applies to HVAC/furnace filters. Higher MERV can catch smaller particles, but very high-MERV filters may restrict airflow in some systems.

Important safety note

Air cleaners can reduce airborne particles, but they do not fix the source of a problem. Mold growth, water leaks, heavy smoke exposure, and HVAC issues may require cleanup, ventilation, or a qualified professional.
