🧠 Why AHAM + HEPA Matters
HEPA (High‑Efficiency Particulate Air) filters trap 99.97% of particles ≥ 0.3 µm—think dust, asbestos, smoke, pollen, even some bacteria/viruses. True heavy‑hitters.
AHAM Verifide® CADR ensures a purifier delivers what it promises—for smoke, pollen, dust. That clean‑air speed matters for tackling nasty stuff fast!
Pro tip: Match the smoke CADR to at least ⅔ of your room’s square footage—aiming for full filtration in under an hour.
