Humidifier runs but room humidity does not increase noticeably.

Safety: Normal operation troubleshooting only; no internal work required.

• Check capacity: Verify that the humidifier's rated coverage matches the room size.
• Close openings: Close doors and windows to prevent moisture from escaping.
• Increase setpoint: Set the target humidity higher (e.g., 50–55%).
• Clean unit: Clean the atomizer membrane and mist outlet as described in the manual.
• Placement: Place the unit away from heating vents and direct sunlight, and at least 30 cm from walls.
