Product review (5 stars): Works as advertised
The reason I feel compelled to comment on this filter is because of my own ignorance.

Let me explain. A couple of weeks ago, I noticed that the filter over our stove (which had been in place for at least 14 years) looked and felt like something  you'd find on the beach after boat accident and a major oil spill. Thinking the filter was an irreplaceable component of the range hood, I began soaking and cleaning it and carefully scrubbing the muck off. I'd let it dry, realize it still felt like a gunky scratchy mess and go at it again.  After a day or two of this a light bulb went off and it occurred to me that the dang thing might actually be REPLACEABLE! So I came to Amazon (of course) and (of course) found a replacement here. It arrived and fit perfectly. So this quantum leap in knowledge may be inflating my grade, but this item from Broan fits and it works and I was very happy to toss its predecessor. Could I have found one of these babies at a hardware store at a lower cost? Maybe so -- but probably wouldn't have remembered to go looking for one. I am once again thrilled with the selection and ease of purchasing that Amazon affords me.
