INNOVATIVE AUTOMATIC CLEANING TECHNOLOGY: Innovative microfilters prevent the passage of small dirt particles, thereby extending the service life of the motor. Automatic cleaning technology involves rotating the motor worm wheel in the opposite direction to remove any dirt left on the filter. Pressing the wind speed button for 3 seconds can reverse the direction of the wind. ULTRA LOW NOISE: Unique and powerful brushless motor, providing strong wind power while reducing operating noise by 30%. Low speed 35db, medium speed 55db, and high speed 60db. The hair dryer weighs only 0.7 pounds per unit, is small, foldable, and easy to store, suitable for travel; 360° rotating magnetic attachment nozzle, easy and convenient installation. DUAL ION SYSTEM FOR BETTER HAIR CARE: Compared to negative ions, 500W positive and negative ions can greatly reduce restlessness and static electricity, close hair phosphorus sheets, reduce branching, eliminate static electricity, lock in up to 95% of the natural moisture content of hair, and protect hair quality. Hair is softer, brighter, smoother, and more glossy. MULTIPLE MODES: 12 adjustment modes, 3 speed setting, 4 hot setting, able to switch between hot and cold air with one click, meeting the needs of hair under various conditions, high temperature quick drying, low temperature setting, and safe delayed shutdown. LOW TEMPERATURE QUICK DRYING: The brushless motor rotates at 11W, which is 6 times the air pressure of a traditional hair dryer. The strong airflow can quickly remove heat and moisture from the hair surface, increg the drying speed by 30%. The built-in microprocessor and intelligent temperature transducer reduce the heat sensation on the scalp, prevent hair damage from heat, and achieve the effect of low temperature quick drying.
