Humidifier produces white dust on nearby surfaces.

Safety first: Unplug the humidifier before servicing.

Steps to reduce white dust:

• Switch to distilled water: Use distilled or demineralized water in the tank to drastically reduce mineral output.
• Install/replace demineralization cartridge: If your Electrolux humidifier supports it, install a new demineralization cartridge or mineral filter according to the manual.
• Clean unit: Wipe down internal surfaces and the mist outlet to remove existing mineral deposits.
• Adjust output: Run the humidifier at a lower output setting to reduce airborne mineral concentration.

Note: White dust is not a mechanical failure but indicates water quality issues.
