How this works
Required CADR = floor area × ceiling height × air changes per hour ÷ 60. Models must meet that number at their certified maximum output. Electricity cost assumes the certified operating wattage for your hours per day at a flat price; quieter speeds use less power and clean less air.
Filter prices, noise and retail claims are not included yet. Learn more in the air changes guide, CADR explained and our methodology.
