Humidifier produces visible white dust on nearby furniture.

Safety first: Unplug the unit before changing water treatment components.

• Step 1 – Switch to distilled or demineralized water: Using low-mineral water greatly reduces white dust.
• Step 2 – Use AIRCARE additives (if applicable): For compatible models, use manufacturer-recommended water treatment additives or demineralization cartridges.
• Step 3 – Clean surfaces regularly: Wipe nearby surfaces with a damp cloth to remove existing dust.
• Step 4 – Maintain wick and reservoir: Replace wick filters on schedule and clean the reservoir to prevent mineral buildup that can flake off.

White dust is not a mechanical failure but indicates high mineral content in the water; changing water quality is the primary solution.
