I have just acquired this new job and we have an Armstrong Air Utra V Tech 80 furnace.

It came with a blue 16 x 25 filter which hadn't been replaced in 9 months. I went to Ace Hardware and bought a 16 x 25 filter which I found they do not fit.

I need to purchase the original filter that came with the system. I guess instead of throwing them away, you just clena them?? Who knew that?? HELP - I've checked at Ace and they don't sell them. Does anyone know where I can purchase these original filters??
Thanks!

The original filter is called a hog hair filter I believe and you cut them to size. If it does not look like this post a picture of what you have.
