Whirlpool Aluminum Filter Measures 11 1/4"" x 11 5/8"". For non-ducted installation. Fits models RH4830XR and RH4836XR. Replaces part number 8190221. AirFilters.com This washable aluminum filter is used in ducted range hoods and microwave ovens to remove grease from the air. We recommend that the filter be washed as often as required to prevent grease build up and a resultant decrease in air flow. Soak in a solution of hot water and degreaser for 10-20 minutes. Agitate gently to remove loosened grease. A residue of grease on the filter after washing is acceptable as this helps retain grease. Purchase one today!
