Functionally great

My only criticism of the filters is that the color of the material is bright yellow and green on one side, which in my system has to face down. The colors are bright and quite noticeable against my white ceiling and vents.

Air Filter replacement

These filters work well. I have 3 return air vents, so I replace filters often. These are a good fit and easy on the budget.
