Product review (2 stars): Not the product pictured!
Do not believe the picture. The filter sold by Golden Supply is NOT NuTone brand! It is a generic Chinese-made knockoff that sort of fits the same opening (but not quite), not supposed to be disposable (unlike the original), no blue and gold stripes at all, and the frame is made out of cheap thin aluminum foil. It arrived with the frame bent in a few places... just don't want to deal with the hassle of mailing it back since it's cheap anyway.

Basically, it's a fake and I don't even know if there's any functional benefit to it other than a vent cover.
