Product review (4 stars): Broan BP29 8-3/4-Inch by 10-1/2-Inch Aluminum Replacement Filter for Range
This appears to be the same flimsy aluminum filter as the one that came with the range hood.  The only filtration is the layers of loose wire mesh covering the frame.  This is primarily to catch grease and condensation from entering your range hood exhaust pipe and works as well as the factory filter. Delivery was quick but not kind -I had to spend some time bending this back into shape after opening it, but it works fine and was cheaper than going to the hardware store.

This is for a fully ducted (vented to the outside) range hood. If you have a recirculating range hood fan (vents back into the house) then you will need the other model filter that has fabric and charcoal filtration built into it.
