This evaporative air cooler is specially designed to enhance your comfort by drawing in air and cooling it down, creating a refreshing and pleasant place for you. By filling the 6L large-capacity water tank or using 2 reusable ice crystal boxes, the cooling effect can be effectively enhanced, ensuring a continuous flow of cool air for an extended period. The built-in dustproof filter can effectively block dust and pollutants, allowing you to enjoy clean, moisture-rich fresh air. The cooler offers three wind speed settings (low/medium/high), allowing you to freely adjust the wind power according to your personal needs, optimizing air circulation and comfort. Additionally, the automatic left and right swing function distributes the cool air evenly to every corner of the room, making the coolness omnipresent.
