I am very happy with my filters. I needed an unusual size. I previously had to buy 3 smaller ones and duct tape them together every 3 months. Your filters came quickly, damage free, and is a much better quality. It took less than 30 seconds to change out and I noticed a difference in my air quality that same day. I bought a year's supply, so I will definitely be buying again next year!

I ordered the size I needed and the 20x25 is a half in too small LxW. In order to get the exact size I need I have to special order then and it's 169. 00 for 6 of them.

I've used this before in an older home. Now we are in a new construction apartment and works wonderfully.

I’m very happy to see all 3 filters now come in one box. The price increase was quite a shocker. Not sure if I will continue with on line purchase or buy local
