These filters are too wide. We had to force the filters into the opening. We need 24 inches width.

We have a lot of dust in this area, so I go with the highest MERV filter (13) to help with my allergies.

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!!!
