About this product: 【No Leaks】Upgraded Humidifier: ① Equipped with the main unit on top and an 8L large-capacity tank on the bottom. ② Integrated tower-shaped design that prevents water leakage. ③ The humidifier can be filled from the top, so you can add water simply by opening the lid. It uses a suction pump to transport tap water from the water tank to the main unit, making it easy to clean and hygienic. ④ Part of the tank is transparent, so you can see the remaining water level at a glance. ⑤ The humidifier has a large capacity, so you don't need to refill it as often, saving you time and effort. 【With Aroma Case】Gently press the aroma oil case on the back of the humidifier, and the aroma case will pop out. Add 1-2 drops of aroma oil to the sponge inside the aroma case to purify the air. ※ Be careful, as exposure to direct sunlight (ultraviolet rays) immediately after use may cause spots or inflammation. When using aroma oil, it is best not to turn on the ultraviolet light. 【Keeps Water Clean with Water Circulation】The humidifier has a filter installed right after opening the top lid. The water is filtered every time you add water, and it moves from the top to the bottom, then is sucked up by a pump and arrives at the main unit. An ultraviolet light is also installed near the atomization part of the main unit. It can humidify while circulating the air, which is perfect for the current situation! Even if you don't use it as a humidifier by adding water, you can still use it with the air circulator function only. By circulating the air in the room, ventilation efficiency is improved! It feels like the humidifying steam goes upwards, so you don't have to worry about the floor getting soaked, even without using the air circulator!
