Works, just a smidge smaller than other retail filters

It seems to be working great so far. I did notice it was just a tiny bit smaller than the other retail filters I've purchased in the past. The other ones would wedge into my ceiling air return frame, exactly fitting and not falling out. These ones fit, but as soon as I open the return frame they fall out.

Glad you have so many available sizes as local retail stores only have a few standard sizes. Excellent quality filter at a reasonable price.

I had to get a custom size to fit my location. The filter helps with air flow being cleaner.
