Filter quality is great but the size is not accurate should be half a millimeter smaller in all of the directions. Then you want to install that filter that doesn't matter which size you have to damage the filter to fit. I ordered 12 of them in two types six of each ivish I ordered just one

These measurements were custom made and they fit perfect. The size is now saved and I can keep ordering them as needed. I have used them for quite a few years.

I have a 3 zone system that requires 4 different filters and found these to be the most cost effective.

This filter is for my air intake. The filters work great but the orange and green colors are noticeable in my ceiling. My old ones weee white. Never thought about the color until I put this in. .
