The two filters required for our Heat / AC unit reside on the interior side of the removable panel door. When purchasing filters from a source other than Discount Filters, we found they were NOT truly the size they claimed. Filters did not easily fit into place because the filters cardboard framing exceeds the 1 inch declaration. I questioned the sales agent regarding that issue when making this purchase. She stated the dimensions provided by Discount Filters are accurate - that we would not be disappointed. SHE WAS ABSOLUTELY CORRECT!
