Customer Reviews for Century GUH95A 16 x 25 x 1 Accessory Slide Return Air Filter Kit

My Century GUH95a gas furnace installer like many, did not fabricate an air filter slide-retainer slot. He did however fashion a 2" X 18" slot opening between the main return air to furnace (filter-position). The common filter: 16"X 25" X 1" installed was floppy & far from air tight ie. more air passed around it! After trying to retrofit misc. rails & shims, I was happy to find this filter frame kit. IInstallation was only a challenge due to it not being incorporated in the original installation. I was able to install through lower furnace (blower-area) bulk head door & sealed with HVAC-Metal tape & some furnace-grade blk. foam rubber. WORKING BEAUTIFULY.... PS: recommend install during initial installation. WRT
