Castle Filters One-Year HVAC Furnace Filter, MERV 6, 14x20x1, 1 Count (Pack of 1)

  • MERV 6: The Super-Flow MERV 6 air filter is an alternative to traditional see-through woven fiberglass or washable filters. The air filter offers superior protection of your equipment and home while still allowing maximum air flow.
  • AC Air Filter: Castle Filters have 400% more surface area for dust and other particles to collect. The internal foam is treated with a sticky material to collect more dust while letting the air pass through.

  • Save Energy and Lower Land Fill Contribution: Castle’s HVAC air filter helps you save energy with its advanced filtration technology and also helps in generating less waste as it need not be changed every month like a standard filter.
