Hart & Cooley Inc.: Filter Seal
January 3, 2011
The SMART Filter Seal installs over a furnace filter slot to prevent unconditioned air from getting drawn into the HVAC system. It also keeps dust and pollutants out, improving indoor air quality. Energy is saved by not having to heat or cool air leaking into the HVAC system.
