FilterLock® is a patented two-piece system designed for use with 1-inch air filters that eliminates air leakage at the filter slot/door to improve indoor air quality (IAQ) and reduce energy consumption. Energy Star lists air leakage at the filter slot as one of four major issues with duct work in the home.

If not properly sealed, harmful airborne contaminants can enter the heating, ventilating and air conditioning (HVAC) system through the filter slot/door and bypass the air filter. FilterLock® installs in seconds with no tools to eliminate unfiltered air from entering the system through the filter slot/door. Since dirty air that leaks into the HVAC has to be conditioned, FilterLock® can also reduce energy consumption.
