About This Product

FilterLock can be used with any 1 in. air filter to improve indoor air quality and reduce energy consumption. The patented, 1-size-fits-all product effectively seals the filter slot/door after the filter is installed, to eliminate the possibility of harmful airborne allergens and pollutants from entering the HVAC system due to air leakage. FilterLock is used by heating and air conditioning, energy auditing and weatherization professionals to stop air leakage, enhance HVAC system integrity and improve the performance of 1 in. air filters.

  • Sealing air leakage/by-pass at the filter slot/door forces dirty air to travel through the filter instead of around it
  • Reusable overlapping 2-piece design works with any brand 1 in. air filter up to 25 in. L
  • Filter lock has built-in magnets which hold it securely to the metal duct work
  • Installs in seconds without the use of any tools
  • ENERGY STAR identified air leakage at the furnace and filter slot/door as 1 of 4 major problems with duct work
  • FilterLock satisfies the department of energy recommendation that the furnace filter slot be covered to avoid air leaks
