Product review (1 stars): Will not fit my Rangaire hood.
While advertised as fitting a Rangaire hood, it's just a little too big by about 1/8"-3/16" in both length and width. As it's rather flimsy, I bent the frame attempting to install. Since I couldn't return it at that point, I pushed and shoved it into place. Looks like crap, but it's mostly out of sight. Should work better than no filter.

I'll deal with finding the right size filter in a year. :).
