How to Clean and Replace a Microwave Charcoal Filter

A charcoal filter works as an air filter in a microwave. It helps to keep your kitchen atmosphere good with fresh air without any smell or odor issues.

When you cook raw food in the microwave, the food releases some odors during the process. These odors go out of the microwave through its vent system but the charcoal filter keeps the odor and sends the fresh air out to your kitchen.

Most over-the-range microwaves come with a built-in charcoal filter located on top or front or back or anywhere on the body. You can refer the user manual of your microwave to find location of the charcoal filter.

Can I Clean My Microwave Charcoal Filter?

Yes, you can clean your microwave charcoal filter but not completely. Some experts recommend to clean a microwave charcoal filter with help of a can of compressed air but the manufacturers of microwaves suggest not to clean it.

The manufacturers recommend to check the charcoal filter of your microwave once a month and replace it every six months. For people with heavy use of the microwave, it is good to replace the charcoal filter every three months.

Generally, a microwave has two filters called the grease filter and the charcoal filter. The grease filter and charcoal filter help to keep the microwave safe & hygienic as well as keep the air in your kitchen free from unpleasant odors.

[A] Grease Filter:

The grease filter is made of either stainless steel or aluminum mesh. The grease filter provides protection against grease particles and debris, it prevents them from entering the vent system of the microwave. You should wash & clean the grease filter of your microwave at least once a month.

[B] Charcoal Filter:

The charcoal filter is made of high quality microfiber or similar material. The charcoal filter prevents the unpleasant odors from entering your kitchen when it’s released from the microwave during the cooking process.

Some microwaves have two grease filters and one charcoal filter, while some microwaves don’t have a charcoal filter. The microwaves that are vented outside the house don’t require a charcoal filter.┬áSo, you should check the user manual to know how many filters your microwave has.

Can I Clean My Microwave Charcoal Filter with Compressed Air?

You should not clean your microwave charcoal filter with compressed air because it does not clean the filter properly and can damage it. You should not use a damaged charcoal filter in your microwave as it won’t be able to filter odors. So, the unpleasant odors will fill up your kitchen as you cook something in your microwave oven.

Can I Wash My Microwave Charcoal Filter with Water?

You should not wash your microwave charcoal filter with water because water will damage it. The charcoal filter contains charcoal pores that absorb the odor coming from the microwave to pass only fresh air out of it. The water damages the charcoal pores which will reduce the ability of charcoal filter to absorb the odor.

So, there is no point of cleaning your microwave charcoal filter with a can of compressed air or washing it with water as both methods damage the filter. Instead of doing this nuisance, you should simple replace your microwave charcoal filter time to time.
