What to do if the Mijia Smart Air Purifier 6 makes abnormal noises?

If the Mijia Smart Air Purifier 6 makes abnormal noises, please refer to the following steps:
  1. Check whether the filter is properly installed and that the protective packaging has been removed;
  2. Inspect the purifier for any foreign objects that have fallen inside. If found, open the filter compartment and remove the objects;
  3. Check the laser particle sensor area for any debris;
  4. Ensure the air purifier is placed on a flat and stable surface to avoid vibrations that can amplify operational noise;
  5. If the noise persists, try power cycling the device by unplugging it for 10–20 seconds and then restarting;
  6. If none of the above steps resolves the issue, contact after-sales service for further inspection.
