Cooling: Leafless swan fans are primarily used for cooling purposes. They circulate air in a room, creating a breeze that helps to lower the temperature and make the environment more comfortable. 2. Air purification: Some leafless swan fans are equipped with air purification features, such as built-in filters or ionizers. These functions help to remove dust, pollen, and other airborne particles, improving the air quality in the room. 3. Noise reduction: Leafless swan fans often operate silently or with minimal noise compared to traditional fans. This makes them suitable for use in bedrooms or quiet spaces where noise can be disruptive. 4. Energy efficiency: Many leafless swan fans are designed to be energy-efficient. They consume less power compared to traditional fans, which can help reduce electricity bills. 5. Safety features: Leafless swan fans are generally safer to use compared to fans with exposed blades. Since they don't have visible blades, there is a lower risk of accidents or injuries, especially for children or pets.
