Design & Appearance

It comes with a comfortable design. The rectangular appearance occupies up less space in the room and looks very elegant. In addition, the device is much more compact than others. During its manufacture, the electrical system and the water tank were separated to offer a 100% safety. To add water and fill the tank, it is not necessary to remove it or lift the lid. For this, there is a special grid.


The case and all the parts in contact with your skin are made of eco-friendly materials. And the internal surface of the water tank has an antibacterial covering that prevents the development of harmful microorganisms. At the top, there are two buttons with indicators (Wi-Fi signal level and water level). It can even be operated by children.

Despite its level of hygiene, it is advisable to periodically clean the inside walls of the tank with a clean cloth to remove sediment.


It has two fans for better circulation. The first fan forces the air inwards. It is then saturated with moisture (using a resonator in the piezoelectric element). The moistened air already prepared is pushed upwards due to the second fan. The air dissipates upwards because it avoids the appearance of puddles near the device. Also, thanks to this, the manufacturer managed to eliminate the effect of fog. Humidity is expelled uniformly.

To maintain normal humidity in the room, the humidifier evaporates on average approximately 240ml of water per hour. This is enough so that the humidity of the air of a room with an area of up to 36m² complies with the standards.

To prevent inactive operation, the device is equipped with a function to control the amount of water. If the water runs out in the tank, or also, if you remove the tank during operation, the system will shut down automatically.
