Humidifier (Honeywell console or portable) does not produce visible mist or increase humidity.

Safety: Unplug the humidifier before cleaning or servicing. Do not immerse electrical parts in water.

Steps:

• Check water tank: Ensure the tank is full, cap is tight, and tank is properly seated on the base.
• Inspect and replace filter: For evaporative models, remove the wick filter. If it is stiff, brown, or heavily scaled, replace it with a Honeywell‑approved filter.
• Clean transducer (ultrasonic): For ultrasonic models, gently clean the metal transducer disc with a cotton swab and white vinegar to remove mineral deposits.
• Verify fan operation: Ensure the fan runs and draws air through the filter; replace the fan motor if not operating.

Tip: Use distilled or demineralized water to reduce mineral buildup and extend component life.
