This Range Hood Charcoal 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 is no longer functioning properly, you should replace it promptly with this item. This aluminum charcoal filter is a universal part that can be used across several brands; check to see if your model number is compatible. Size: 11-3/4" L x 11-1/4" W x 1/4" H. Installing this accessory will require basic hand tools, some disassembly of the range hood and novice repair experience. You must shut off the house circuit breaker for the appliance before installing this part.
