• The water level in the water tank decreases even when the unit is not operating for humidification.

  Even when the unit operates only for air purification, air draft causes natural evaporation of water and slight humidification results. Thus, the water level in the water tank decreases. If the product is used only for air purification, discard water from the water tank and humidifying tray before operating.
