Product review (3 stars): Does the Job but Cheapo Quality
OK replacement for a who-knows-how-old filter in a bathroom ceiling vent fan. Worked/fit in conjunction with the new replacement plastic grill but had to remove the center grommet as the hole was too small for either the original or the new (replacement grill) mounting bolt,. Surprised how easily the grommet came out, but then the thing is cheapo quality: The filter mesh isn't anywhere near the tight "weave" and thickness of the old filter, and the outer perimeter binding edge seems thinner than a dollar store foil pan. Best thing was finding it on Amazon; couldn't find it in Home Depot or any local hardware/appliance store. I'd probably buy one again when needed, still,  it's a shame how the quality of something as simple as this has been cheapened over the years.....
