My air purifier makes an unexpected noise

Make sure that you have removed the plastic cover from the filter (not applicable to all models and filters).

Make sure that nothing blocks the air inlet and outlet.

Make sure that no object or dust is clogged around the filter. If there is, remove the filter and clean the purifier with a vacuum cleaner.

To remove the filter(s) to see if it is causing the noise:

  • Turn off your air purifier and unplug it.
  • Remove the filter(s).
  • Plug in the unit and turn it on. If the noise disappears, install a new filter. If the noise is still there, please contact the retailer where you bought the air purifier. They will help you according to their warranty conditions.
