What the AI looks for in Microwave Replacement Filters
- Filter type
- Grease filters are washable metal mesh mounted under the unit. Charcoal or carbon filters sit behind the top vent grille and cannot be washed. These are different parts with different jobs, and many over-the-range models use both.
- Venting mode
- You need a charcoal filter if the microwave recirculates air back into the kitchen. If it is ducted to the outside, it usually only needs the grease filters. Without a charcoal filter, a recirculating installation does nothing for odors.
- Part number and dimensions
- Match the OEM filter part number from the manual, or match the old filter's length, width and thickness exactly. Filters that are only slightly off leave gaps or will not seat in their clips.
- Replacement interval
- Replace the charcoal filter on the schedule in the manual, roughly twice a year for regular cooking. Wash the grease filters regularly and replace them only if damaged. Saturated carbon stops absorbing odors, and clogged grease filters cut airflow and raise the risk of a grease fire.
Brands that matter
- GE Appliances: OEM charcoal and grease filters for its over-the-range lineup.
- Whirlpool: Its OEM filters also fit many Maytag, KitchenAid and Amana units.
- Frigidaire: OEM filters for Frigidaire and Electrolux over-the-range models.
- Samsung: OEM filters are specific to each over-the-range series.
- LG: OEM charcoal and grease filters for its over-the-range models.
What to avoid
- Aftermarket charcoal filters that list no OEM part numbers they replace.
- Washing charcoal filters, which ruins them.
- Running an over-the-range unit with the grease filters removed.
- Buying a charcoal filter for a unit that is ducted to the outside.
Questions
Do I need both filter types?
Every over-the-range unit needs its grease filters. The charcoal filter matters only when the unit recirculates air rather than venting it outside.
