FAQ

What does “True HEPA” mean?

“True HEPA” commonly refers to a filter media that meets a high capture-efficiency benchmark in standardized testing conditions (often cited as 99.97% at 0.3 microns). Real-world performance also depends on CADR, room size, and usage.

What is CADR and why does it matter?

CADR (Clean Air Delivery Rate) indicates how quickly a purifier can remove smoke, dust, and pollen from the air. Higher CADR generally means faster cleaning for a given room size.

Do I need a purifier with activated carbon?

If your priority is odors, smoke, or VOCs, carbon can help. For dust/allergens alone, HEPA media is usually the main driver.
