Beurer humidifier emits a white dust on nearby furniture.

Safety: No internal electrical work is required.

Mitigation steps:

• Switch water type: Use distilled, demineralized, or reverse-osmosis water instead of hard tap water.
• Replace filter: If your Beurer model includes a demineralization or anti-limescale cartridge, replace it according to the manual (often every 2–3 months).
• Reduce output: Lower the mist output level to reduce airborne mineral concentration.
• Increase ventilation: Slightly open a door or window to allow dust to disperse.

White dust is not a mechanical failure but indicates high mineral content in the water. Long-term, it can clog the transducer and sensors, so addressing it is important.
