Great service. My unit requires an odd-size filter and the only stores in this area don’t carry that size. It is so convenient to be able to receive the filters on a scheduled basis without even having to think about it.

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.
