                        Comments about Koch Filter Corporation 20" X 20" X 1" MERV 11 Pleated Filter:

                        Sizing is very misleading. Advertised as 19 3/4 X 19 3/4 but actually is 19 1/2 X 19 1/2. This causes the filter to be lifted up when the air handler turns on and then falls back down onto the filter grate when the handler turns off. VERY noisy! This also allows unfiltered air to go around the filter into the air return.
