Why Is CADR Important for Air Purifier Effectiveness?

The Clean Air Delivery Rate (CADR) is crucial for evaluating the effectiveness of an air purifier. CADR measures the volume of clean air produced by an air purifier over a specified time. It is expressed in cubic feet per minute (CFM) for three specific pollutants: smoke, pollen, and dust.

The Association of Home Appliance Manufacturers (AHAM) provides an authoritative definition of CADR. According to AHAM, CADR indicates how quickly an air purifier can remove airborne particles from indoor air, acting as a reliable standard for consumer guidance.

CADR is important for air purifiers due to several reasons. First, it allows consumers to compare the performance of different air purifiers objectively. Higher CADR values indicate better performance in removing specific pollutants, leading to healthier indoor air quality. Second, CADR directly correlates to the size of the room where the air purifier can be effective. A higher CADR is necessary for larger spaces, ensuring pollutants are removed efficiently.

Technical terms related to CADR include “airflow rate” and “particulate matter.” Airflow rate refers to how quickly air circulates through the air purifier, while particulate matter encompasses tiny particles suspended in the air, which can include dust, pollen, and smoke.

The mechanisms involved in CADR include the processes of filtration, adsorption, and deactivation of pollutants. Filtration captures airborne particles using filters, which may be HEPA (High Efficiency Particulate Air) filters or activated carbon filters. Adsorption refers to how some materials attract pollutants onto their surfaces. Deactivation occurs when pollutants are rendered harmless through chemical reactions.

Specific conditions that contribute to effective CADR include proper sizing of the air purifier for the intended room, regular maintenance like changing filters, and the type of pollutants present. For example, a purifier with a CADR of 200 CFM would be suitable for a room of approximately 200 square feet with standard ceiling height, efficiently reducing smoke or allergens in that space.
