Aprilaire 2120 air cleaner filters must be replaced twice per year if you have heating and air conditioning or once per year if you have just heating. Aprilaire 2120 air cleaner filters are not cleanable or washable. Failure to replace the filters often enough may cause problems with your heating and cooling system.

GREAT NEWS
We are pleased to announce an upgrade kit is NOW AVAILABLE for the model 2120 air cleaner. This upgrade kit will increase the efficiency of your existing air cleaner to a MERV 13 (A 65% Improvement). Additionally it removes the necessity of using the pleat spacers which makes future filter installation a breeze. You can view a video of this simple upgrade BELOW.
