Humidifier emits a white dust on nearby furniture

Safety: Unplug the unit before servicing.

• Switch water source: Use distilled, demineralized, or reverse-osmosis water to prevent mineral dust.
• Install or replace cartridge: If your Stadler Form model supports a demineralization cartridge, install a new genuine cartridge and replace it at the recommended interval.
• Clean surfaces: Wipe down the room surfaces and the humidifier outlet to remove existing dust.
• Reduce output: Run the unit at a lower mist setting to minimize aerosolization until water quality is improved.
