Maintaining the cleanliness of your Dyson air purifier filter is crucial for the device’s optimal performance. This comprehensive guide will walk you through the basics of Dyson air purifier filter cleaning, common issues, troubleshooting, the recommended replacement schedule, and maintenance tips for longevity.

Dyson Air Purifier Filter Cleaning Basics

Maintaining the efficiency of your Dyson air purifier involves regular filter cleaning. This process is straightforward and can be done in a few simple steps. Remember, Dyson air purifier filters are not designed to be washed like vacuum filters. They are more efficient at cleaning the air and therefore more susceptible to water damage.

Step-by-Step Guide to Cleaning Your Dyson Air Purifier Filter

  1. Turn off and disconnect your machine at the wall socket. This is a crucial safety measure to prevent any electrical accidents during the cleaning process.

  2. Remove your Dyson filter(s). Depending on your specific model, the process of removing the filter may vary. Generally, you should be able to easily locate and remove the filter.

  3. Wash filters in cold water only. Avoid using detergent or washing the filter in a dishwasher or washing machine. Rinse the filter under the water supply, then gently squeeze the water out of the filter. Repeat this process until the water runs clear.

  4. Dry filters by leaving them in a warm place for 24 hours, until completely dry. It’s important to ensure the filter is completely dry before reinserting it into the machine to prevent any potential water damage. Avoid drying the filter in a tumble dryer, microwave, or near a naked flame.

  5. Replace the filters. Once the filters are completely dry, you can replace them in your Dyson air purifier.

Important Notes

  • Dyson air purifier filters are designed to be highly efficient at cleaning the air, making them more susceptible to water damage. Therefore, they should not be washed like vacuum filters.

  • It’s recommended to replace your Dyson air purifier filter every 12 months. However, if you run your air purifier frequently or are experiencing a lot of indoor air pollution, you may need to change the filter more often.

  • If you don’t replace your Dyson filter, the filters will get clogged up. This clogging will not only make the air purifier incapable of cleaning the air but also can make the air purifier not function at all.

Additional Tips for Maintaining Your Dyson Air Purifier

  • Clean the exterior of your machine. Use a dry or damp cloth to wipe the outside of your machine. Use a soft brush to clean the holes in the outer cover. Wipe away any remaining dust or debris with a dry or damp cloth.

  • Reset the air purifier filter life indicator. After replacing the filtration unit, you need to reset the air purifier filter life indicator. Without resetting it, it will give a false warning in the future.

By following these steps and tips, you can ensure that your Dyson air purifier continues to function at its best, providing you with clean and fresh air in your home or office.

Common Issues and Troubleshooting

If your Dyson air purifier is not working as expected, it could be due to a dirty or damaged filter. Here are some common issues and troubleshooting tips:

  • Unusual smell: This could be due to a dusty filter. Consider replacing the filter.
  • Reduced airspeed: This could be due to a clogged filter. Try cleaning or replacing the filter.
  • Machine starts operating on its own: Check if the auto mode is turned on. If the issue persists, contact Dyson support.

Dyson recommends replacing the air purifier filter when the remaining filter life is displayed on the screen. Dyson air purifier filters are fully sealed, trapping pollutants rather than leaking them back into the room.

Maintenance Tips for Longevity

To ensure the longevity of your Dyson air purifier, follow these maintenance tips:

  • Regularly clean your machine and check for blockages.
  • If your machine is dusty, wipe it with a damp lint-free cloth.
  • Look for blockages in the air inlet holes on the filter and the small aperture inside the loop amplifier. Use a soft brush to remove dust and debris.
  • Don’t use detergents or polishes to clean your machine.
