How to Clean an Air Purifier?

Air purifiers are great appliances that help to remove impurities from the air, creating a healthy and comfortable living space. However, to ensure that your air purifier continues to function optimally, it is important to keep it clean. In this article, we will discuss the steps you need to take to clean your air purifier effectively.

Why Clean Your Air Purifier?

The primary function of an air purifier is to remove airborne impurities such as dust, pet dander, pollen, and other allergens from the air. Over time, these impurities accumulate on the air filters, reducing the efficiency of the purifier. In addition, if the air filters are not cleaned or replaced regularly, they can become a breeding ground for mold, bacteria, and other microorganisms, which can pose a health risk to you and your family.

Cleaning your air purifier regularly ensures that the air filters are free from impurities, allowing them to function optimally. It also reduces the risk of mold and bacteria growth, creating a healthier living environment.

Why Clean Your Air Purifier

How Often Should You Clean Your Air Purifier?

The frequency at which you should clean your air purifier depends on several factors such as the type of air purifier, the quality of the air in your environment, and the frequency of use. Generally, it is recommended to clean your air purifier at least once every three months. However, if you have pets or live in an area with high levels of pollution, you may need to clean your air purifier more frequently.

Step 1: Turn off the Air Purifier

Before you start cleaning your air purifier, ensure that it is turned off and unplugged from the power source. This will prevent any electrical shock and damage to the appliance.

Step 2: Remove the Air Filter

The air filter is part of the air purifier that collects impurities from the air. To remove it, refer to the manufacturer's instructions. In most cases, you will need to open the front or back panel of the air purifier and slide out the air filter.

Step 3: Vacuum the Air Filter

Once you have removed the air filter, use a vacuum cleaner to remove any loose dust or debris. Hold the vacuum nozzle a few inches away from the filter and move it over the filter in a back-and-forth motion. This will remove any loose dirt or debris from the filter.

Step 4: Wash the Air Filter

After vacuuming the filter, you can wash it using water and mild detergent. Fill a basin with lukewarm water and add a few drops of mild detergent. Place the filter in the basin and gently agitate it for a few minutes. Then, rinse it thoroughly with clean water to remove any soap residue. Allow the filter to air dry completely before reinstalling it.

Step 5: Clean the Air Purifier Housing

While the air filter is drying, you can clean the housing of the air purifier using a soft, damp cloth. Ensure that you do not use any harsh chemicals or abrasive cleaners as this can damage the appliance. Wipe the housing gently to remove any dust or debris.

Step 6: Reinstall the Air Filter

Once the air filter is completely dry, reinstall it in the air purifier according to the manufacturer's instructions. Ensure that it is properly seated and secured in place.

Step 7: Power on the Air Purifier

Finally, plug in the air purifier and turn it on. Ensure that it is functioning properly and that the airflow is normal. You can also check the air filter indicator to see if it needs to be replaced.


Cleaning an air purifier is a straightforward process that can be done with just a few simple steps. By regularly cleaning and maintaining your air purifier, you can ensure that it operates efficiently and provides clean air for you to breathe. In addition to regular cleaning, it is important to change the air purifier's filter periodically. Most air purifiers use a HEPA filter that needs to be replaced every 6-12 months, depending on usage.

It is also important to note that an air purifier is not a substitute for good indoor air quality practices. To maintain good air quality, ensure that your home or office is well-ventilated, avoid smoking indoors, and clean regularly to prevent the accumulation of dust and other particles. By combining these practices with the regular cleaning and maintenance of your air purifier, you can ensure that the air you breathe is clean and healthy.
