Product review (1 stars): I think "filter" is a misleading term to use for this :(
I feel so completely disappointed and ripped off.  It is shiny like they said, but it's less than half the thickness of the original, and there's no filtration material whatsoever, just some shiny aluminum mesh.  A mosquito could stroll right through, but a large housefly might squeeze through.  I guess it could keep my fingers or a utensil from getting stuck in the fan blades, but that's about all it's good for :(
