The Range Hood Charcoal Filter traps grease from the exhaust air of your appliance to prevent it from entering the blower and vent, potentially causing build-up and damage. This filter is designed to be used with 36" stainless steel range hood models WVW73UC6LS and WVW53UC6LS. Replacing this accessory will require basic hand tools, some disassembly of the appliance and novice repair experience. You must unplug the appliance or shut off the house circuit breaker before installing this accessory.
