De'Longhi humidifier produces very little mist even at maximum setting.

Safety first: Unplug the humidifier and empty the tank before cleaning.

Step-by-step:

• 1. Descale transducer: For ultrasonic models, soak the transducer area in a 1:1 solution of white vinegar and water for 10–20 minutes, then gently scrub with a soft brush. Rinse thoroughly.
• 2. Clean mist outlet: Remove any nozzle or outlet cover and clean with warm water to remove deposits.
• 3. Replace wick filter: For evaporative models, replace the wick filter if it is stiff, brown, or has a strong odor.
• 4. Use distilled water: To reduce future scaling, use distilled or demineralized water.
• 5. Reassemble and test: Fill the tank, reassemble, and run at maximum output to confirm improved mist production.
