Frequently Asked Questions

What does 'coverage at 4.8 ACH' mean and why do you compute it?

Air change rate says how many times per hour the unit moves a full room volume of air through its filters. Manufacturers often advertise the largest room the unit can serve at just 1 air change per hour, which produces a big impressive number. The AHAM standard most reviewers use is 4.8 air changes per hour. We divide the manufacturer's stated coverage by its air changes per hour and multiply by 4.8, so every model on this site can be compared on the same basis.

Is the 4.8 ACH figure our own test result?

No. It is arithmetic on the manufacturer's own stated coverage. We do not run physical tests and we do not present a computed figure as a measurement.
