Perfect Size!

I am so happy to have found the size! I was shoving a 20x20x1 in there because that is what the previous owners had used. Also, delivery was fast!! Thanks again... and i’ll be ordering on the regular from you!

Excellent Service

My AC return has an odd size filter. Filter King filters to fit. I just happened to see them on a Google search. I will not hesitate to use them in the future.
