Raydrop KC-RD05UP Humidifiers for Bedroom, 2.5L Top Fill Cool Mist Humidifiers for Home,

This humidifier uses ultrasonic waves to make the top of the water atomization, the too high water level will make the ultrasonic wave conduction efficiency decreases, which will lead to the humidifier having little or even no mist coming out.

This humidifier converges ultrasonic waves through the mist tube and the small circle to make the water on top atomized. Therefore, make sure the mist tube is clicked into place, and the small circle is in the mist tube and floating on the water.

Please avoid the water into the air outlet and air inlet while cleaning, or filling water, which will damage the electrical components. Dry all parts with a cloth. Make sure all parts are completely dry before reassembling or storing.

Best place to put a humidifier is 2 4 feet above the floor where the most airflow is. It is recommended to put a tray underneath the humidifier, if you place it on a non waterproof surface, the locally high humidity levels may wet the surroundings.

It depends on where you live. In some areas, water is richer in minerals. The humidifier won’t instantly go haywire if you do use tap water, but in the long term will cause scale and you need to maintain it more often. Distilled water is recommended.
