How many times does it change the air per hour?
That depends on the size of the room. Measure your room’s length, width and height in feet and multiply them together to get your room’s volume in cubic feet. The OAC100 cleans 5100 cubic feet per hour and the OAC200 cleans 7800 cubic feet per hour. Divide the cubic feet of the air cleaner by the volume of your room and you will have the number of air changes per hour.
