      My furnace is an older model and it was hard to find the right size till I stumbled on this website years ago. I never need to look in the stores since deliver is super fast.

        Filters go into air plenum for central A/C and forced air heating. Service was exactly as advertized, and fit was exactly as stated.

            Unable to find this size filter anywhere at the local stores. When we were able to find them labeled as the size of these, they were actually slightly larger. We had to force them in making them less effective as they bent up slightly on the edges.

                  I looked all around town and could not find a filter the correct size to fit my AC unit. The company that installed the AC told me to use a reusable filter that I had to take out and spray with the hose. It's impossible to get all the dirt out. I prefer using a fresh filter each time. Online ordering could not have been easier. I just gave them the size I needed...no problem!

                        [...] excellent air filters. My order couldn't have gone easier. Since I order 6 filters, I was concerned about storage and keeping them dust free. But my concern was needless as they were shipped in a nice sturdy box that can placed in the garage until next month when I need another filter.
