【Four Birds with One Stone: Humidification, Heating, Quiet Operation, and Human Sensor - 4-in-1】This ceramic heater not only has a heating function but also a humidification function. Simply pour an appropriate amount of water into the water tank, and mist will come out like a humidifier. Using high-frequency ultrasonic technology, it transforms water into fine particles, reducing them to 5μm or less, which quickly settles dust in the air and humidifies without wetting the desk. It not only effectively disinfects but also helps regulate room temperature, purify the air, and improve symptoms of dry skin, hay fever, and seasonal rhinitis. It's easy to use for beginners and the elderly. Ceramic fan heaters have the advantage of quick heating, with warm air coming out immediately after turning on the power. Also, unlike oil heaters, they don't emit unpleasant odors. They warm the air cleanly without polluting it. This fan heater has an ambient light mode, and the gently lit LED mood light allows you to relax. You can turn the ambient light ON/OFF as you like, and your usual room will quickly transform into a healing space. 【Ceramic Fan Heater that Detects Human Movement】Equipped with a sharp motion sensor detector, the human sensor detects movement and automatically turns ON when someone approaches, and automatically turns OFF if no one is present for more than 3 minutes. No troublesome power operation is required, saving electricity. The detection area is highly accurate, with a sensor range 50% wider than regular human sensors (sensor range: maximum distance about 2m, 60° up, down, left, and right). You don't have to worry about fire even if you forget to turn off the electric fan heater when you go out! It's easy to use even for beginners, and it's also recommended as a gift for the elderly during the dry season. *The human sensor function can be toggled ON/OFF by pressing and holding for 3 seconds. 【2.4m³/min Large Air Volume, Rapid Heating in 2 Seconds! Airflow/Warm Air】Turn it ON, and warm air comes out immediately. The large air volume ceramic heater with humidification has a stronger air volume and faster wind speed compared to regular ceramic heaters. According to research by the editorial department, the air volume of a typical ceramic heater is about 1.2㎥/min. As a guideline, a model with 1.3㎥/min or more has a strong air volume. In addition to the two-stage adjustable warm air function for use in cold seasons, there is also an airflow (cool air) mode. 【ECO Constant Temperature Mode for Energy Saving and Indoor Temperature Display】 【Tip-over OFF, Overheat Protection, Cooling Function, V0-Class Flame Retardant】
