Can You Wash and Re-Use Dyson Air Purifier Filters?

It’s crucial that you clean your Dyson air purifier filter regularly to ensure that it’s working properly. However, you cannot wash your Dyson air purifier filter as you would your clothes or dishes, or you run the risk of damaging it.

You should also not be washing your Dyson filter with harsh detergent or other cleaning products, as it will cause your filter to break down and lose its overall effectiveness. You can, however, gently wash your air purifier with water and allow it to air dry.

What You’ll Need?

To clean your Dyson air purifier filter, you’ll need the following:

  • A vacuum cleaner
  • Dust cleaning brush
  • Soapy water
  • Cloth

As seen from the above, no specific tools are required to clean your Dyson air purifier filter; just the basics are needed to get started.

The soapy water will then help get rid of any dirt that still remains.

How To Clean Dyson Air Purifier Fan Filter (Step By Step Guide)

With regards to cleaning a Dyson air purifier fan filter, it’s important to note that most Dyson air purifiers are generally cleaned the same way. With the Dyson Pure Cool Air Purifier filter, however, you’ll need to make sure that you’re not just cleaning the filter, but also cleaning the Dyson Pure Hot+ Cool Link.

Here’s how you’ll go about cleaning a Dyson air purifier fan filter:

  1. Turn off the machine. Make sure that you’ve unplugged your Dyson air purifier air filter, as the last thing you’d want is for your air purifier to still be operational. Moreover, you won’t be able to clean the filter when your air purifier is still on.
  2. Remove the filter. Most of the filters for the Dyson air purifier are found near the cyclone. Go ahead and lift the cyclone before removing the filter to clean it.
  3. Some of the air purifiers contain two filters, so make sure that you’re checking the back of the air purifier or in the ball. If there is another filter, take it out as well.
  4. Remove the dust with a vacuum cleaner and brush. After you’ve opened the filter, you’ll see lots of dirt blocking the filter. You’ll want to start by using a brush to clean away the dirt. Otherwise, you can also use a vacuum cleaner – just make sure that you’re doing it gently, as the filter material is delicate.
  5. Rinse the filter. Before rinsing the filter, make sure that your Dyson air purifier filter is waterproof. Dyson has two types of filters – while one is waterproof, the other one isn’t. If the filter is waterproof, you can rinse it under regular water. If it isn’t, go ahead and wipe it gently using a slightly damp, clean cloth.
  6. Remember to use only cold water for the above before allowing your fan filter to air dry for 24 hours before putting it back into your device.
  7. Replace filters. Once the filters are completely dry, go ahead and reinstall them in their original position. Then, plug the socket in, and your air purifier will be all good to go.
