This Microwave Grease Filter traps grease from the exhaust air of your oven to prevent it from entering the blower and vent, potentially causing build-up and damage. If your current filter can no longer be cleaned and is not functioning properly, you should replace it promptly with this item. This silver filter is a universal accessory that can be used across several brands; check to see if your model number is compatible. Size: 6" x 13-1/2". Replacing this accessory will require no disassembly or repair experience.
