A High-Efficiency Particulate Air (HEPA) filter is a type of air filter that is designed to capture and remove very small particles from the air. It is widely used in various applications, including residential, commercial, and industrial settings, as well as in medical facilities and cleanrooms.
If you have a HEPA air purifier filter, over time these filters accumulate dust, allergens, and other particles, which can hinder their effectiveness. Regularly cleaning the filter is essential to ensure optimal performance.
Proven Steps to Keep Your HEPA Air Purifier Filter Clean
To prepare for cleaning your washable HEPA filter air purifier, gather the following materials:
- Clean, Soft Brush
- Mild Dish Soap

Here’s a step-by-step guide on how to clean your HEPA air purifier filter that you can follow:
Total Time: 30 minutes
Turn Off and Unplug
Before you begin, make sure the air purifier is turned off and unplugged from the power source. This precaution ensures your safety during the cleaning process.
Remove the Filter
Most HEPA filters are easily removable. Refer to your air purifier’s user manual for specific instructions on how to safely remove the filter.
Once removed, carefully inspect the filter for any visible signs of damage. If the filter appears torn or excessively dirty, it may be time to replace it.
Gently tap the HEPA filter against a solid surface to remove loose debris and dust. Be cautious while doing this to avoid causing any damage to the filter. Use a soft brush to remove any stubborn particles from the surface of the filter.
Take care not to brush too vigorously to prevent tearing or damaging the delicate filter material.
Washing the Filter
If your HEPA filter is washable, follow these steps to clean it effectively:
a. Fill a sink or basin with warm water and add a small amount of mild dish soap. Stir the water gently to create a soapy solution.
b. Submerge the filter in the soapy water and let it soak for 15-20 minutes. This will help loosen and dissolve trapped particles.
c. Gently agitate the filter in the water to dislodge any remaining debris. Avoid excessive rubbing or scrubbing, as it can damage the filter.
d. Rinse the filter thoroughly with clean water until all soap residue is removed. Ensure that water flows through the filter from the clean side to the dirty side, following the airflow direction marked on the filter.
e. Repeat the rinsing process until the water runs clear, indicating that the filter is clean.
Drying the Filter
Proper drying is essential to prevent mold or mildew growth on the filter. Follow these steps to ensure thorough drying:
a. Gently shake off excess water from the filter and place it on a clean, dry cloth.
b. Pat the filter with the cloth to absorb any remaining moisture. Avoid wringing or squeezing the filter, as it may damage its delicate structure.
c. Set the filter in a well-ventilated area and allow it to air dry completely. This process may take several hours or overnight, depending on the humidity levels.
Reinstalling the Filter
Once the HEPA filter is completely dry, carefully reinstall it according to the manufacturer’s instructions. Ensure that the filter is securely in place before closing the air purifier unit.
Clean air is essential for a healthier living environment, and a clean HEPA filter is a key component in achieving it. By following the step-by-step guide outlined above, you can effectively clean your HEPA filter and prolong its lifespan!
