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, replacing this accessory may alleviate the issue. This accessory can be used across several 36W range good brands; check to see if your model number is compatible. 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. Helpful Tip: For optimum performance of your vent, change the filter at least once per year or when a loss of airflow can be detected.
