Features

Protect Your HVAC System: FilterLock is a patented two-piece seal system designed for use with 1” air filters that eliminates air leakage at the filter slot/door to improve indoor air quality (IAQ) and reduce energy consumption.

Improve Air Quality: If not properly sealed, harmful airborne contaminants such as allergens, dust, and gases like carbon monoxide can enter heating, ventilating and air conditioning (HVAC) systems through the filter slot/door and bypass the air filter.

Energy Efficient: By stopping air leakage in your HVAC system, you’ll help reduce utility bills, save energy, and improve overall indoor air quality. Energy Star lists air leakage at the filter slot as one of four major issues with duct work in the home.

Easy To Install: FilterLock’s universal one-size-fits-all seal magnetically attaches to duct work to cover furnace filter slot door. Two-piece design works with any 1” furnace filter up to 25” long.

Additional Features: Reusable, easy on / easy off design for long-term use. Seal measures approximately 25 x 4.8 x 0.1 inches when both pieces are installed.
