Kitchenaid W11745046 Microwave Hood Combination Charcoal Filter for Smart Low Profile Models (9-IN X 10 1/4-IN)

Model W11745046 Microwave 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. For optimum performance of your vent, change the filter every 6 months or when a loss of airflow can be detected.
