Cleaning my air

This is not my first time ordering from this company and won't be the last time. I did go back to the store bought to try to save money and boy was that a big mistake. So I am back and I will stay a customer till the end

Our Filters Are Not Made of Cardboard!

Air Sponge crushes other AC filters

Air Sponge Filters are crafted from industrial strength aluminum alloy, not cardboard! Your permanent reusable frame is built to last. It's backed by a 10 year warranty!

You get Air Sponge's patented, custom made air filter frame.  This permanent, 100% aluminum frame features a unique Leak-Guard seal, to eliminate bypass.  And to enhance performance, a permanently attached, electrostatic screen.  We'll  make your new frame to any size that you need.  That means you will always have a filter that fits perfectly!

You then choose what type of replaceable air filter media goes inside your frame.  Select the media that suits your needs best, you can always switch to a different type when you use them up.

Replaceable air filter media assures a new, clean air filter every time.  No more guessing if your filter is really clean & healthy.

The combination of it's perfectly sealed aluminum frame, and our advanced air filtration inserts, puts this air cleaning system... in a class by itself.

Best Filters

Could not live or breathe without these filters. Very seldom use my inhaler at home because of them. You can see the results when you change the filter so you know it is doing what they say it will do. Have tried HEPA filters, charcoal filters, and certain other filters that gave me asthma attacks from the materials they were made from. These are absolutely perfect.

Patented Leak-Guard Seal TM Gives You 100% Air air conditioning filters

To make sure that all the air and pollutants go through your furnace filter and not around it, your new filter features our patented Leak-Guard seal. When your air conditioner or furnace turns on, the difference in pressure causes an air tight seal. No bypass means your filtering 100 % of the air. That means the harmful particles are trapped in the AC filter, not in the lungs of you and your family.

An industry - leading 10 year warranty! If your air conditioner filter breaks for any reason return it for a
free repair or replacement.
