Product review (5 stars): Purchased for an old Tappan vent hood.
I purchased this item to replace the filter on a Tappan Range hood.  I didn't want to purchase a new vent hood, so I painted the one that originally came with the house (built in 1972).  It was yellow - to tell you how old it was!  The vent hood has an exposed fan & I could not find a domed filter anywhere.  I purchased this one not expecting much.  It does the job, and tolerated my small bending adjustments to make it fit snugly.  If you're looking for a vent hood filter to replace an older model - this one should do the trick!
