What to do if the Mijia Smart Water Purifier N800G makes noise during use?

The Mijia Smart Water Purifier N800G is a reverse osmosis purifier, and its booster pump can produce some noise during operation. If installed inside a cabinet, this noise does not affect daily life.
If the noise is excessive, please check the following:
  1. Ensure the purifier does not resonate with nearby objects, remove nearby objects, and test again.
  2. Check if there are objects on top of the purifier, remove them, and test again.
  3. Slight noise is normal if the purifier is outside a cabinet or the cabinet has no door.
  4. Noise can occur when the water tap is closed because the purifier performs an automatic rinse.
  5. If the noise remains excessive, contact our official after-sales service for further inspection.
