Humidifier function produces white dust or mineral deposits on nearby surfaces.

Steps:

• Use distilled or demineralized water: Switch from hard tap water to distilled water to reduce mineral output.
• Install demineralization filter: If your Olimpia Splendid model supports it, install a compatible demineralization cartridge in the humidifier tank.
• Reduce output: Lower the humidifier output setting or move the unit farther from sensitive surfaces.
• Clean surfaces: Wipe affected surfaces with a damp cloth to remove existing dust.
