Air conditioner filters play a crucial role in keeping the air inside your home clean and healthy. 

However, these filters can become clogged with dirt, dust, and other pollutants over time, reducing their effectiveness and potentially leading to a variety of health problems. 

To keep your air conditioner filters working at their best, it is important to clean them regularly using natural, homemade cleaners.

Here is a detailed guide on how to clean air conditioner filters with homemade natural cleaners:

Identifying the Type of Filter

Before you begin cleaning your air conditioner filters, it is important to identify the type of filter you have. There are several different types of air conditioner filters, including fiberglass filters, pleated filters, and HEPA filters. 

Each type of filter has its own unique cleaning requirements, so it is important to know which type you have before you begin.

Removing the Filter

Once you have identified the type of filter you have, the next step is to remove it from the air conditioner. The process for removing the filter will vary depending on the make and model of your air conditioner. 

Consult the owner’s manual for specific instructions on how to remove the filter from your particular unit.

Preparing the Homemade Cleaner

There are several natural, homemade cleaners that you can use to clean your air conditioner filters. One popular option is a mixture of water and white vinegar. 

Simply mix equal parts water and white vinegar in a spray bottle and shake well to combine. You can also add a few drops of essential oils such as lemon or tea tree oil for added cleaning power and a pleasant scent.

You can also try using baking soda. See How to Clean an Air Conditioner Filter with Baking Soda.

Cleaning the Filter

Once you have prepared your homemade cleaner, it is time to clean the filter. Begin by spraying the filter with the cleaner and using a soft brush to gently scrub away any dirt or dust. 

For tough stains, you can leave the cleaner on the filter for a few minutes before scrubbing. Once you have scrubbed the filter, rinse it thoroughly with water to remove any remaining cleaner.

Drying the Filter

After cleaning the filter, it is important to dry it thoroughly before reinstalling it in the air conditioner. 

To dry your air conditioner filter, you can hang it in a well-ventilated area or use a fan to circulate air over it.

Keep your air conditioner filters away from direct sunlight, as prolonged exposure may cause them to become brittle and potentially damage the filter.

Be sure to let the filter dry completely before reinstalling it in the air conditioner to prevent mold growth.

Reinstalling the Filter

Once the filter is dry, it is ready to be reinstalled in the air conditioner. Consult the owner’s manual for specific instructions on how to reinstall the filter in your particular unit. 

Be sure to reinstall the filter correctly to ensure that it works properly.

Important Reminder:

It is important to note that cleaning air conditioner filters can be a potentially hazardous task. Before attempting to clean your air conditioner filters, be sure to turn off and unplug the power to the unit to avoid the risk of electric shock

Additionally, if you have any concerns about your ability to safely clean your air conditioner filters, it is best to call a professional for assistance.

Also, be aware that some air conditioning systems require special filters and it’s not recommended to clean them with homemade natural cleaners or water. 

Always check the owner’s manual or consult a professional before attempting to clean any filter to avoid any damage or malfunction to the unit.


Regular cleaning of air conditioner filters using natural, homemade cleaners is an easy and effective way to keep the air in your home clean and healthy. 

By following these simple steps, you can ensure that your air conditioner filters are working at their best, helping to improve the air quality in your home and protecting your health.

With proper cleaning, you can enjoy the benefits of a well-functioning air conditioner and breathe easy knowing that the air in your home is clean and healthy.
