Fantastic

I just bought a new house that had a 16x20x1 filter in my unit. That left a huge gap. After going on filter buys website I ordered the correct size and they fit perfectly and I couldnt be happier.

Short story: I have an uncommon AC filter size that Filterbuy actually was able to provide. They responded quickly to my order and their price was very reasonable. I intend to keep using them moving forward.

Everything about the filter is what I need to fit, and protect our A/C from the damaging effects of dust and dirt on our cooling unit.

What can I say? Filterbuy filters are easy to install, making it more likely that I'll actually change them on schedule. They fit perfectly and apparently do the job they're intended to do. I have no criticism of this product and intend to continue purchasing them into the foreseeable future.
