Know Your Filters

Microwaves typically have two types of filters: grease filters and charcoal filters. Grease filters capture grease and particles from stovetop cooking, while charcoal filters, found in over-the-range models, help remove odors from the air recirculated by the microwave.

Cleaning Grease Filters: A Step-by-Step Guide

  1. Locate the Filters: Grease filters are usually found on the underside of the microwave. They should easily slide out or pop off with a gentle tug.
  2. Soak and Scrub: Place the filters in a dish of hot, soapy water and let them soak for a few minutes. For a deeper clean, add a tablespoon of baking soda to the mix. After soaking, gently scrub the filters with a soft brush or sponge to remove any stubborn grease.
  3. Rinse and Dry: Rinse the filters thoroughly under running water. Shake off any excess water and let them dry completely before reinserting them into the microwave.

Replacing Charcoal Filters: Know When and How

  1. Replacement Frequency: Charcoal filters cannot be cleaned and should be replaced every six to twelve months, depending on your cooking frequency and the type of foods you cook.
  2. Find the Right Filter: Ensure you purchase the correct replacement filter for your microwave model. This information can usually be found in the microwave’s manual or by contacting the manufacturer.
  3. Easy Swap: Accessing the charcoal filter may require removing the grill or panel at the top of the microwave. Remove the old filter, insert the new one, and replace any covers or panels you removed in the process.

How Often Should You Clean or Replace Your Microwave’s Filters?

  • Grease Filters: Clean them at least once every month if you cook frequently. If you notice the filters are visibly dirty or your kitchen becomes smoky during cooking, it’s time for a cleaning.
  • Charcoal Filters: Replace these every six to twelve months, depending on usage. A noticeable persistence of odors despite cleaning the grease filters is a tell-tale sign that it’s time to replace the charcoal filter.
