CADR = Clean Air Delivery Rate

CADR is the key industry standard for rating the overall efficiency and effectiveness of indoor air purifiers. CADR is defined as the measure of the delivery of contaminant-free air by an air purifier, expressed in cubic feet per minute. CADR testing measures three contaminants: smoke, dust and pollen. Smoke is measured on a scale of 25 to 450, dust on a scale of 10 to 400, and pollen on a scale of 25 to 450. The actual test results for this product are below.
