Product review (3 stars): Tweaking Necessary.
First issue: Measured the original filter, could not find the exact measurements according to my tape-ruler. Had to take a chance to the closest fit found. Lucky me, I got it right.

Second issue: Received with frame slightly bent. No big deal, was able to straiten the frame with just a little care.

Third issue: The mesh filter bowed upward contacting the fan making  a scraping noise. This was more of a bothersome issue to fix. The goal was to work the mesh downward to where it will eventually sag down away from the fan blades. Mission accomplished.

All in all, the filter works as expected, but it should have been a plug n play scenario if a little care was taken in the quality of construction.
