This Cooktop Downdraft Vent 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. This filter is duct-free and uses charcoal to help remove cooking odors. This accessory can be used across several brands; check to see if your model number is compatible. Replacing this part will not require hand tools, disassembly of the appliance or previous repair experience.
