Air purifiers list their air filtration capabilities in terms of room size and frequency of air exchanges, sometimes listed as clean air delivery rate (CADR) or you may see a number for cubic feet per minute (CFM). A smaller unit might say it can exchange the air in a 500-square-foot room twice per hour. So that model should be able to pass all of the air in a 250-square-foot room through the filter every 15 minutes, but a 1,000-square-foot room would probably be outside its effective range. Of course, there’s no standard for manufacturers to adhere to when it comes to these calculations, but typically, larger air purifiers can handle large rooms.
