I was happy to be able to find these filters. The dimensions were exactly what I needed. I tried purchasing a 20 x 25 x 4 at one of the large brick and mortar hardware stores but it was not the correct Actual Size dimensions, which is important to having it fit properly during installation.

It installed easily. Just a little short, but works well & there isn't a size that would work any better.I am happy with my purchase. Have been using these for the past year.

I’ve paid much more for this size filter. This was slightly smaller but fit fine. I also like that it came in a set of 4- so I’m ready to change next time.

Bought to use with my geothermal unit. Works well to catch dust. We will likely have to replace ours every month, but my technician said they should last every 3, for a smaller house/family. I like having the option to toss and replace vs cleaning an existing one with the hose in the older months. Will keep my geothermal in good shape.
