Then there is CADR or Clean Air Delivery Rate, which affects the coverage area of the air purifier, which in turn affects the air change per hour (ACH) rating. CADR is usually measured as cubic meter of air delivered in hour or cubic foot of air delivered in a minute. Basically it tells how much of air can the purifier clean in a given time. Higher the number, the better it is. ACH on the other hand is number of times an air purifier filters all of the air in a room in one hour. So, an ACH rating of 3 means that the purifier filters the air in the room three times in one hour.
