My Journey to the Right Size Filter
on February 14, 2025
Posted by: Anonymous
I had a 16x25x5 filter when my new furnace was installed a little over 3 months ago. As I would discover from my local hardware store and twice with Filterbuy, it was a really particular "exact size" filter that the broad size classifications would not be able to replace, being much too large. Finally, Filterbuy provided me with a 5x25x4 filter that was close enough to what I needed at no cost to me. Thank you Filterbuy!

I can tell the difference in the air. I'm sure I will be ordering again as this size is not something you will find in a store. Thank you very much!!!

Size too big

This filter is 5. 25 thick, my filter slot is 5 , be careful and read the exact size before you buy. 20X20X5 does not mean it is 5 thick.

Wont be using them for a while. I am hoping they will be as good as the ad says. I wish the price would come down.
