Patented Filter Technology: Castle Filters use 3 layers of ¼-inch open-celled foam, with a patented tacky center layer that catches dust like fly paper. Proudly made in USA - US patent #10,183,249 B2.
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.
Lasts One Year: The furnace filter holds up to 20 times more dust than a pleated filter. While pleated filters need to be replaced about once a month, the Castle Air Filter lasts one year which is 4-12x longer than the others.
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.
