Raymond D Alameda , CA January 29, 2019 Replaced grease screens on my 20 yr old over the range microwave Easy fix replaced old ones slipped in nicely and plan to put in dishwasher to clean and store away. Still looking for a charcoal filter for the top exhaust fan that fits or cut a larger one so it fits. If you carry them let me know.
