How to Clean Dyson Air Purifier Filter – (Step-By-Step Guide)

  1. Turn Off and Unplug the Air Purifier: 

    The first step in cleaning your Dyson air purifier filter is to ensure that the device is turned off and unplugged from the power source. This is an important safety measure that will help prevent any damage from occurring while you’re cleaning the filter.

  2. Remove the Filter: 

    Most Dyson air purifiers have 2 clips on each side of the unit. Push down both clips simultaneously to open the top cover of the device. Now, carefully remove the air filter from the unit body.

  3. Vacuum Off the Dust: 

    Once you have removed the filter, use any vacuum cleaner with a hose attachment to suck out any dirt or debris inside the filter. You can also use a soft-bristled brush for this purpose. Gently brush the filter to remove any remaining dust or dirt.

  4. Rinse the Filter with Cold Water: 

    Now rinse the filter under the cold-water supply and gently squeeze the water out of the filter, repeating the process until the water runs clear. It’s important to avoid using hot water, detergent, or any harsh chemicals, as these can damage the filter. 

  5. Allow the Filter to Dry: 

    After washing, shake off excess water and allow the filter to air-dry for 24 hours. Do not use heating elements to speed up the drying process. The filter must be completely dry before reinstalling it in the air purifier.

  6. Reinstall the Filter: 

    Once the filter is fully dry, carefully push the filter to the body of the air purifier till you hear the click sound. This will close the top cover of your unit. Make sure to install it in the correct orientation. Also, check the filter seal is correctly seated to the body.

  7. Turn On the Air Purifier

    Now you have a cleaned filter installed in your air purifier. Plug the unit in an AC socket and turn it on to enjoy clean air in your home.

When Should You Clean Dyson Air Purifier Filter

In general, cleaning the Dyson filter every month is recommended, but if you have pets and live in an area with high levels of airborne particles, you may need to clean it more frequently. One way to determine when to clean your filter is to check the filter indicator on your Dyson air purifier. This helpful feature will indicate when the filter needs cleaning or replacement. 

There are some signs that also indicate when it’s time to clean your filter. For instance, if you notice a drop in airflow from your air purifier, it could be a sign that the filter is clogged and needs cleaning. Similarly, if you feel an increase in dust or allergens in your home, it’s time to clean the filter. Remember to follow a safe and effective method when cleaning your filter to avoid damaging it and reducing its effectiveness.

How Often Should Dyson Filters Be Replaced?

Timely replacement of the air purifier filter is essential to maintain its effectiveness in improving the indoor atmosphere. So, how often should you replace your Dyson air purifier filters? Well, the frequency of filter replacement can vary depending on the usage and quality of air in your home. 

According to Dyson manufacturers, the HEPA and activated carbon filters in Dyson air purifiers should be replaced every 12 months. However, if you use your air purifier more frequently or if your home has a lot of air pollutants, you may need to change the filters more than once a year. Furthermore, the filter indicator will alert you when it’s time for a replacement.

By replacing your filters at the recommended intervals, you can ensure that your air purifier works at its best, providing you and your family with clean and healthy air to breathe.
