The Smartmi Evaporative humidifier consists of two parts that operate relatively independently. The upper part includes the fan and circuits. The water tank and evaporating plates are located underneath. Smartmi decided to separate water and electricity by integrating the electric control and fan structure. It is convenient to add water through the grille at the top, and this also ensures that the motor stays dry. To avoid stale odors the humidifier blows dry all surplus water after the lowest water level is reached.
