I was disappointed to see that these MERV 11 filters are orange and beige. It makes it difficult to see how dirty a filter is when changed. They used to be white, as are the MERV 13.
Every year I research multiple sites to see who has the best deals on filters. This company always comes out on top. I only wish the cardboard shell had less surface area to it. I do believe it obstructs some of the flow of my air through the filter. I end up taking a pair of scissors and utility knife to cut away some of the cardboard to increase the flow. Maybe this could be a consideration for future design changes?
