              Comments about Koch Filter Corporation 12" X 18" X 1" MERV 11 Pleated Filter:

              Beware the filter sizes are 1/2" smaller than the size listed and if the purchase is for multiple filters they will be around for a while. Ordering online is very confusing about actual measurements. It is very disappointing!
