Frequently asked questions

What is CADR?

CADR (Clean Air Delivery Rate) is the volume of filtered air a purifier delivers, in cubic feet per minute. Smoke CADR is the most useful single number for comparing cleaning capacity.

How do you estimate recommended room size?

Our recommended room size uses approximately 4.8 air changes per hour with an eight-foot ceiling. Manufacturer coverage figures may use a lower air-change rate and are shown separately.

What counts as a quiet air purifier?

We treat a published noise figure under 30 dB as quiet. Use the noise filter to find bedroom-friendly models when a dB rating is available.

What does True HEPA mean here?

A model is marked HEPA when manufacturer or listing specs name a HEPA or True HEPA filter. If that field is missing, we do not infer it.
