When and how to change the microwave charcoal filter

You probably don’t even know about this hidden microwave. But if your kitchen often smells like yesterday’s dinner, it might be time to replace your microwave’s charcoal filter.

Between central air conditioners, dishwashers, vacuums, and ovens, there always seems to be a household filter that needs your attention. Well, we have another one to add to the list: the microwave carbon filter. If you are wondering what exactly it is, you will most likely need to replace it.


What is a Microwave Charcoal Filter?

Microwave charcoal filters are found in microwaves that do not have an outlet to the outside. The filter absorbs unwanted odors during cooking.

In fact, most kitchen models have two filters: one for charcoal and one for grease. The carbon filter is usually near the top of the device, behind a vent; check user manual to confirm location. The grease filter is located under the microwave, in front of the hob.

When to replace the microwave charcoal filter.

About every six months. You can tell if a filter needs to be replaced just by looking at it. Here are some warning signs:

  • The filter appears to be filled with cooking grease.
  • When you cook, you smell different than the food you prepare. This suggests high fat accumulation from previous meals.
  • If the filter surface looks shiny, there is a lot of grease present. Normally, the filter should appear opaque and porous.

Consult your microwave oven manual to find out how to replace the charcoal filter and what size to buy. Most microwaves require you to unplug the unit or disconnect from the power supply. Next, remove the vent; it can be just by pushing a button or removing a few screws. Remove the old filter and put in a new one. Ready.

Can the microwave filter be cleaned?

Simple answer: no. You cannot clean a carbon filter; you need to replace it.

Fortunately, they are cheap. But while you’re replacing the filter, take the opportunity to clean the rest of your microwave.

Be sure to clean the air vent, grease filter, and charcoal filter compartment, as they are both very dirty. Wash the sink vent with warm soapy water and wipe the compartment well with a damp cloth.
