Why is my Philips HU4801/01 Humidifier not humidifying?

If your Philips Humidifier is not humidifying the air, ensure the water tank is filled and the upper unit is correctly placed. Also, excessive room ventilation might be the cause, so try closing doors and windows. For models like HU4801, the recommended room size is 25m².
