22x22x2 MERV 11 Pleated Air Filter

great service and quality filters

I saw an interesting way to purify a large volume of air on an episode of ASK THIS OLD HOUSE. They used four of these filters taped together as a square box with the air flow facing in.Then they mounted a 22" square 3 speed fan on the top drawing the air through the filters and out the top. Sealing off the open bottom of this arrangement allowed a large volume of air to pass through the filters removing dust and germs. I purchased these filters to build and test this system to try and eliminate dust from our pellet furnace. So far it seems to be working great.

I ordered the wrong filter size called the customer service team & they reshipped
the correct size AT NO COST to me. Unbelievably great experience. I will never purchase filters anywhere else!

The filters work Wonderful there is only one problem they seem to not fit correctly we have to push a lot to get them in but otherwise they good Maybe am buying them to large maybe they have to be 22221 I don't know can you please email me and let me know what I am doing wrong thank you

Easy to use and prompt reply back to a question I had about the product. Highly recommend this company and the filters are exactly what one would expect.
