Great Experience at Walmart

Walmart always has a large supply of furnace filters. I am always able to find exactly what I need. These filters met my expectations and satisfied my need. Additionally, they were priced competitively. Finally, delivery was great — they arrived quickly and in perfect condition.

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.

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?
