Product review (4 stars): Just what I needed for a GE cooktop range with range-top vent.
Happy to have found this.  Bought a new house, the range they had in there was one with an intensely powerful range-top vent, circa late 1990's.  Noticed that the filter was nasty nasty nasty nasty nasty, way beyond salvage, probably is the original one that no one ever one cleaned or serviced.  As others have said, this was the measurement, and pretty much the main option on Amazon.  So I bought it.  Definitely not quite as heavy as the original that was in there, but it fits nicely, problem solved.  Now I have a clean, non-nasty, filter.  I suspect if I take care of this one, I won't need to use the second one ever, but it's nice to have :)
