How Do I Determine the Ideal Size of Air Purifier for My Space?

To determine the ideal size of an air purifier for your space, you should consider the room size, the air changes per hour (ACH) required, and the Clean Air Delivery Rate (CADR) of the unit.

Room size: Calculate the area of your room by multiplying the length and width in feet. For example, if your room measures 15 feet by 20 feet, the area is 300 square feet. Most air purifiers specify their effective coverage area. Select a purifier that matches or exceeds your room size.

Air changes per hour (ACH): ACH indicates how many times an air purifier can filter the entire volume of air in a room in one hour. For typical residential use, aim for an air purifier that provides at least 4 to 5 changes per hour. For example, if your room is 300 square feet with an 8-foot ceiling, that corresponds to a volume of 2,400 cubic feet. An air purifier with a sufficient ACH rating will efficiently maximize filtration.

Clean Air Delivery Rate (CADR): CADR measures the volume of filtered air delivered by the air purifier, rated for three pollutants: dust, pollen, and smoke. Choose a unit with a higher CADR rating, as it indicates better performance. For instance, if the CADR for smoke is 250, then the purifier can filter that amount of smoke from the air every minute. It is recommended that the CADR should be at least two-thirds of the room size in square feet.
