Product review (3 stars): Definitely cheap and flimsy
As some other reviewers noted, this filter is very think and flimsy. The "charcoal" layer may not even be charcoal.  It fits perfectly into my range hood, but I have doubts as to whether or not it will  be effective in terms of odor removal. I looked extensively online for alternatives but it was seemingly impossible to tell if what I found on an alternate site would be any better quality. Since Broan is not making these filters themselves anymore, we are probably stuck with getting filters made by third parties  that are the right size, but pale in terms of effectiveness and quality.
