- PROTECT YOUR HVAC SYSTEM: FilterLock is a patented two-piece magnetic seal system designed for furnace systems with 1” air filters, eliminating air leakage at the filter slot/door to enhance indoor air quality and reduce energy consumption.
- IMPROVE AIR QUALITY: Prevent harmful airborne contaminants such as allergens, dust, and gases like carbon monoxide from entering your HVAC system. Properly sealing the filter slot/door ensures that pollutants don’t bypass the air filter.
- ENERGY EFFICIENT: Reduce utility bills and save energy by effectively stopping air leaks in your HVAC system. This not only enhances overall indoor air quality but also addresses one of the four major ductwork issues identified by Energy Star—air leakage at the filter slot.
- EASY TO INSTALL: Enjoy hassle-free installation with FilterLock’s universal, one-size-fits-all seal that magnetically attaches to ductwork to cover the furnace filter slot door. This convenient two-piece design is compatible with any 1” furnace filter up to 25” long.
- ADDITIONAL FEATURES: Benefit from a reusable, easy on/easy off magnetic design that ensures long-term use. Once both pieces are installed, the seal measures approximately 25 x 4.8 x 0.1 inches, providing a perfect fit for your needs.
