Whole-home Carrier humidifier produces white dust or mineral deposits around vents.

Safety first: Turn off furnace power and water supply before servicing the humidifier.

Steps:

• 1. Replace water panel: Install a new Carrier water panel/pad to reduce mineral buildup.
• 2. Consider water treatment: Use softened water if compatible with your humidifier, or install a scale inhibitor filter on the feed line.
• 3. Adjust humidity level: Lower the humidity setpoint to reduce output if over-humidification is occurring.
