I have a 20x 30 ac filter installed in the ceiling and the grill cover is
cheap and bends and doesnt really latch very well.

I had an older one in our last house, it was cool, it was a magnet to latch it.

I am not sure what this is exactly called to search on internet.
All I am finding is the filter for the AC.

I want the entire housing, that way this one has screws into wood. I have
already had to replace the screws and tighten the entire box in the ceiling.

thanks:confused1:

they are sometimes call Return air filter frames or filter grills.
Try Steelcrest they make a very high quality one that I have used before in a remodel.
