- Cost of maintenance
Air purifiers need regular cleaning particularly if the pollution level is relatively higher where it is being used. Replacebale filters should be replaced every three to six months. Washable filters should also be cleaned regularly at least once a month.
- Size of space
Depending on the size of room, an air purifier should be of sufficient capacity to provide clean air in its surroundings. In Air Purifiers, a term Clean Air Delivery Rate(CADR) is used as measurement of air purifier’s rate of purification in cubic feet per minute. Obviously, an air purifier with higher rating of CADR will perform better. Another term used is ACH (air change per hour) which is an indicator of number of times an air purifier filters all of the air in a room in one hour. One allergic to dust particles need an air purifier of ACH rating of 4.
If room size is 10 x 10 ft and height is 10 ft,
Volume of room = 10 x 10 x 10 = 1000 cubic feet = 28.3168 cubic meter
ACH = 4
Hence, air to be changed in an hour is 28.3 x 4 = 113.27 cubic meter / hour
Hence, you need an air purifier of CADR 113 m3/hr for a room of size 100 sq. ft.
