Air Care filters provide a great balance of HIGH DUST ARRESTANCE and LOW AIR RESISTANCE. There is no industry standard for electrostatic filters. Company's are making filters with cheap imitation media and calling them "Electrostatic". Some permanent filters are too restrictive and can increase your energy bill or even damage your HVAC unit.


94.7% EFFECTIVE (best on the market) - that's 10 times better than a throw-away filter.

EPA APPROVED ANTI-MICROBIAL COATING - to prevent mold and bacteria from growing



THESE FILTERS ARE BUILT TO LAST - just hose it off, air dry, and reinstall.

The Electra Silver 9400 is designed to provide high dust arrestance for your central air system (furnaces and air conditioners). The low 0.12 inch W.G. initial resistance of the Electra Silver will perform best in systems configured with 1 square foot, or more, of filter area for each ton of air conditioning. Two layers of woven monofilament polypropylene with integral anti-microbial material provides 10 times more filtration than a disposable fiberglass filter. The deep loading center layer of non-woven polyester allows the Electra Silver 9400 to prolong the time between washings.
