Product review (4 stars): Doesn't match the original but it actually can be used.
i live in an apartment with a kenmore hood from about 1980. The original filter is very thin and I just couldn't seem to find the correct one so I took a chance and purchased this one. It is not correct BUT the outside dimensions are about the same which left hope. The thickness is probably double that of the original but  luckily the unit has kind of an indentation around the circumference and the clips that hold the filter onto the unit fit into the indentation so all is well and I actually have twice the filter capacity as the previous.
