Four inch filter that fits!
on April 12, 2025

Biggest thing is, this 4 inch filter fits. The filters at the two big home improvement stores are both over 4 inches thick. And wont fit into my furnace. These are sized to fit into a 4 inch opening. Perfect!Shipping is fast and the price is right!

Perfect fit

The filter I ordered fit perfectly. The size wasnt available locally and someone had just put a much smaller one in the furnace, which didnt seemed to be doing much, it was all crumpled up. Our handyman showed me how to change the filters myself. he recommended your website because of your great follow-up of alerting people when its time to change filters. I give him full credit for figuring out the right size to orderit seems to be unusualbut you had it in stock and it arrived quickly.

I bought the right size but it did not fit snuggly in my Honeywell air filter. I will go back to the Honeywell brand.

The filters came VERY fast! The fit is perfect, and I find that the one I used is getting the job done. The company seems to be very efficient. I will purchase from them again!

Filter too small for the Housing
on March 24, 2025
Posted by: Anonymous
The 20x20x4 inch Filter was ACTUALLY 19 1/2 x 19 1/2 x 3 5/8, which is TOO SMALL for the OEM Housing. The FilterBuy filter is smaller by 7/16 x 4/16 x 3/4 inch! In the future I will only buy OEM filters.
