Humidifier produces white dust on nearby surfaces

Safety first: Unplug the unit before cleaning. White dust is typically mineral residue, not smoke.

• Step 1 – Switch to distilled water: Use distilled or demineralized water in your Danby humidifier to prevent mineral dust.
• Step 2 – Clean unit: Wipe down the base, mist outlet, and surrounding surfaces with a damp cloth to remove existing dust.
• Step 3 – Descale regularly: Clean the water tank and ultrasonic transducer weekly with a vinegar solution to remove mineral buildup.
• Step 4 – Use filters if available: If your model supports demineralization cartridges or filters, install and replace them as recommended.

When to call a technician: This is a usage/water quality issue; service is not typically required.
