Say "bye" to Filterbuy.com
Filterbuy.com filters are not true to size. 23 x 20 x 1, is actually 22.5 x 19.5 x 1. The larger size is in LARGE print on website. Smaller size/disclaimer is in small print. They will not replace filters when they don't fit. Been buying for this air handler for 6 years. This is the first company that sent a filter that did not fit and won't make things right. Buy Filtrete instead!
