TopTech High-Efficiency Whole-House Media Filter Cabinet TT-MAC-1422

The TopTech TT-MAC-1422 is a compact whole-house media filter cabinet for the return air of forced-air furnaces, air handlers, heat pumps, and cooling systems. When the system runs, household air is pulled through a 4″ media cartridge that traps dust, allergens, pet dander, and other airborne particles before they reach the coil and blower. That improves indoor air quality and helps the equipment stay efficient instead of loading up with dirt.

The TopTech cabinet is 22-gauge galvanized steel with a fully insulated cabinet and door, a two-stage door seal, and included gasket material to keep leakage low. It uses no electricity. Standard service is MERV 11 media, and the same housing accepts MERV 15 media when you want tighter filtration. Filter changes are straightforward: open the door, swap the cartridge, and use the size printed on the door label. Media typically lasts up to 12 months depending on runtime and indoor conditions. Mounting gasket and hardware are included so the cabinet can be sealed to the equipment and return duct.
