These are tough!

I wanted to see if I could remove the filter material and mesh from a used merv 8 filter, to use the paperboard frame for another purpose. No way; it was like trying to disassemble a unibody car! No wonder these filters hold their shape so well. They're built like tanks

New filters

I ordered these when our furnace was working. It has now quit and we're getting a new furnace installed tomorrow and I have no idea what size it takes but I'm sure it will be the same as the old one. Can I return these and exchange them for the new size what I find out what it is?

Great find!

My a/c went out a couple weeks ago (when it was 3 million degrees). I asked the repair man about air filters. He told me that the expensive filters tend to not let enough air through. So, I'm thrilled to have found Filterbuy! A great price and seem to be doing their job. Will definitely continue buying them.
