This method is based on the natural principle of water evaporation in nature. Although the process of humidifying the air using natural evaporation is not as visible as other types of humidifiers, but In this way you can achieve ideal humidity (40-60%) and automatically maintain it. The particles of water that are visible to the eye (steam, mist) are heavy and need a longer time to evaporate. In addition, if poorly maintained, the devices can adversely affect the breathing process or be harmful to health.
