This set of two Range Hood Charcoal Filters traps grease from the exhaust air of your oven to help 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 charcoal filter is a universal accessory that can be used across several brands; check to see if your model number is compatible. Size of each filter: 7-5/8" diameter by 7/8" thick. Installing this accessory will require basic hand tools, some disassembly of the range hood and novice repair experience. Helpful Tip: Replace your range hood's filter every 6 months to maximize performance and efficiency.
