Product review (5 stars): Perfect Fit
We have a Kenmore range hood that is approximately 20 years old.  The current filters were custom made from Ace hardware, 5+ years ago as we could not find any at local OSH, Lowe's or Home Depot stores that would fit.  They had been cleaned several times and decided to try purchase new one.

We shop alot at Amazon and figured we had nothing to lose since our local hardware strores did not carry this size. These aluminum range hood filters were the closest we could find to the 11 7/8" x 10" size we are replacing. To our surprise, these fit well and have a small plastic tab to help install and remove (our custom-made filters did not have this tab).  I would have no problem purchasing these again if available at that time.
