Why does white residue form on my OSIM uMist Dream Air Cleaner?
- QqrobertsJul 30, 2025
If you notice white particles forming on the top surface of the OSIM Air Cleaner base, it's likely due to mineral residue from tap water. To resolve this, clean the top surface of the base with a clean, dry cloth. Also, ensure you are using only clean, cool tap water to fill the water tank. Unclean water or water containing chemicals can also cause this issue.
