I used it once with water, and then I put it away because I bought an air conditioner. All parts are included except for the instruction manual. 【Powerful Cooling with 3-Sided Wet Filter & 4 Million Negative Ion Air Purification】This multi-functional cooler uses the 2025 innovative atomization cooling technology and a total of 3 wet filters on the back, left, and right sides, increasing the cooling power by 6 times compared to similar products, significantly improving cooling efficiency, and helping to cool down quickly in a short time. 【LED LCD Screen, 3 Modes, 3-Level Wind Speed Adjustment, Ultra-Energy Saving Design】Our powerful cooler is equipped with an LED LCD display and a Japanese panel, which is easier to understand compared to the button-type or mechanical-type coolers of ordinary products. The cooler can switch between 3 modes: normal wind, natural wind, and sleep wind, and each mode can adjust the wind speed in 3 levels: low, medium, and high. "Normal wind mode" operates at the set wind speed. "Natural wind mode" automatically changes the wind speed, providing a wind similar to natural wind. "Sleep wind mode" gradually weakens the wind over time. It supports a comfortable sleep, and the wind speed weakens when you go to sleep, so it is recommended for those who want to reduce the wind speed during sleep. 【24-Hour On/Off Timer Function, Silent Operation】The cooler fan has a convenient 1-24 hour on/off timer, which is convenient when you only want to use it until you fall asleep or when you go out! It automatically turns on and off at the set time, and you can specify the elapsed time to set the automatic on/off timer, enabling efficient operation. 【8L Large Capacity Tank, Top Water Filling, Water Shortage Indication】The large-capacity cooler is innovatively equipped with two water tanks, top and bottom. The powerful and popular cooler can be filled with water from the top, and because it has an 8L large-capacity lower tank, you don't need to frequently add water to the tank in hot weather, and you can rest assured that it will operate continuously for a long time. 【Adjustable Oscillation Louver Function, Easy to Clean】The cooler can deliver cool air over a wider area. The upper and lower louvers can be manually adjusted up to 110° for wind direction, and it also has left and right louvers, which automatically swing the wind 75° to the left and right when turned on. 【PSE Certified, Easy Installation, Package Contents】Unlike air conditioners, this energy-saving cooler does not require an outdoor unit, so there is no need to wait for installation, and you can use it as soon as it arrives.
