HEPA vs Activated Carbon: Match Particle Filtration and Gas Adsorption to the Actual Pollutant

by
Hepa Vs Activated Carbon

HEPA and activated carbon solve different air-cleaning problems. HEPA media captures airborne particles such as pollen, dust, smoke particles, and mold spores, while activated carbon adsorbs certain gases and odor molecules onto its surface. Neither mechanism should be judged from a filter percentage alone because whole-device airflow, seals, media quantity, target pollutant, and replacement condition

Do Air Purifiers Work: Define the Pollutant, Clean-Air Delivery, Room, Run Time, and Outcome

Do Air Purifiers Work

Air purifiers can reduce selected airborne pollutants when the filter mechanism, clean-air delivery, room, placement, run time, and maintenance all fit the job. The useful question is not whether one machine can make a home broadly “clean,” but whether it can reduce a named pollutant in the space where people actually spend time. Less airborne
