Over The Range (OTR) Microwave Filter Help


The grease filter of your over-the-range microwave should be cleaned monthly. This filter helps keep grease and other debris from entering the vent system of your microwave so the exhaust fan can circulate clean air into your kitchen as you cook at your range. If the grease filter is dirty, the exhaust fan won't be able to do its job well.


Additionally, your microwave's charcoal filter will need to be replaced. Unlike the grease filter, the charcoal filter cannot be cleaned and should instead be replaced every 6 months. The charcoal filter helps minimize odors being released into your home as you cook.


You can continue to clean your microwave grease filter monthly, unless physical damage occurs. If your grease filter breaks, it is best to replace it as soon as possible to prevent grease from entering the vent system of your microwave. Once replaced, continue to maintain as recommended.


While cleaning and replacing the filters of your microwave is important, it is also recommended to clean your microwave regularly. Regular cleaning will reduce build up that may ultimately damage your microwave.
