Next, we’ll walk you through how to clean your air conditioner’s filter. Improper cleaning can harm your health, so it’s important to familiarize yourself with the correct cleaning methods and follow the proper steps. This will ensure a thorough clean; otherwise, you may easily damage the filter.
Air Conditioner Filter Cleaning Method
The weather is getting hotter and hotter, so it’s time to turn on the air conditioner. Before using it, be sure to check the air conditioner’s filter for excessive dust and dirt. If you find any, clean it thoroughly; otherwise, it could harm your health. It’s also important to familiarize yourself with the proper cleaning method and follow the correct steps, so you can clean the filter more effectively—and avoid damaging it in the process.

First, remove the dust filter according to the instruction manual, taking care not to touch the metal parts of the indoor unit to avoid damage. After removing the air filter, you may rinse it with water or clean it with a soft brush dipped in a neutral detergent. However, ensure that the water temperature does not exceed 50°C during cleaning, and do not use detergents, dishwashing liquids, gasoline, turpentine, or other similar substances, as these can cause the dust filter to deform and damage its surface. In addition, never use a sponge to clean the dust filter.
After rinsing with clean water, wipe the filter gently with a soft cloth or allow it to air-dry in a shaded area. To prevent deformation of the dust-filter mesh, do not expose it to direct sunlight or dry it over an open flame such as a stove. Now let’s discuss how to clean standard air-conditioner filters: most air-conditioners are designed with removable filters that can be easily detached by gently pressing them. Since the air-conditioner filter is one of the components inside the unit that accumulates the most dust and bacteria, it can be difficult to clean thoroughly with a regular cloth. In such cases, use a brush and detergent to scrub the filter; if you don’t have a dedicated brush, an old toothbrush will work just fine. For filters that haven’t been cleaned for a long time, the dust tends to adhere very strongly, so we recommend repeating the cleaning process several times—scrubbing horizontally on the front side and vertically on the back side—for best results.
When cleaning the panel, dampen a soft cloth with lukewarm water or a neutral detergent and gently wipe the surface, then dry it with a clean, soft cloth. If the cover of the air conditioner’s filter is only lightly soiled, simply rinse it with clean water and then scrub it thoroughly with a clean, soft brush. Experts advise that the air conditioner filter should be cleaned every 1 to 2 months, or at least twice a year; however, if the unit remains unused for an extended period, extra care must be taken during cleaning. It is recommended to entrust the cleaning of household air conditioners to professional cleaning or installation technicians, as most reputable residential air-conditioning installation companies offer this service.
In air-conditioned environments, most spaces are either fully or partially enclosed, with indoor air being recirculated. Air cleanliness is maintained through the air conditioner’s built-in filtration system and the periodic supply of fresh outdoor air, which often results in relatively poor outdoor air quality.
The methods for cleaning air conditioner filters have already been outlined above. As these instructions demonstrate, cleaning the filter is quite straightforward: it should be removed and washed regularly. Otherwise, the accumulated dust can harbor numerous bacteria, posing a health risk, and it can also shorten the lifespan of the air conditioner. Once thoroughly cleaned, the air blown out by the unit will be clean as well.
