Water tank integrated, fluorine-coated "wide-mouth inner container" and "filter-free" ・Wide mouth makes it easy to fill and clean. ・Also, the fluorine-coated inner container makes it difficult for dirt to stick. ・It has a structure without filters that require troublesome cleaning. ■ Clean steam steam type ・It humidifies the room by cooling the boiled clean steam to about 65°C. ■ Triple safety design "Child lock", "Lid opening/closing lock", "Spill-proof structure when tipped over" ・Child lock: Press the key for 3 seconds to disable all operations. (*For safety, pressing the "Off" key will stop operation.) ・Lid opening/closing lock: The lid is always locked with a lever, so it won't open easily even if it tips over. ・Spill-proof structure when tipped over: Minimizes water leakage even if the main unit is accidentally knocked over. (*Please make sure the lid is securely closed. If the main unit is left tipped over, a small amount of hot water may flow out from the steam outlet.) ■ "Humidity monitor" that allows you to see the room's condition at a glance ・You can see the room's condition at a glance with the lamps: "Low humidity", "Appropriate humidity", and "High humidity". ■ "Boiling sound save mode" to reduce boiling sound ・If you are concerned about the boiling sound during use, it slowly raises the water temperature and reduces the boiling sound. ■ "Compact design" with an integrated water tank that doesn't take up much space ■ Convenient double timer "Off timer 2 hours" and "On timer 6 hours"
