【Low Noise/Compact】The dryer's design strategically places air ducts throughout the dryer, reducing vibration and friction, and keeping noise below 59db. This lightweight dryer also features an ergonomic handle and weighs only 600 grams. 【200 Million Negative Ions & Hair Quality Improvement】The new AQielev high-concentration negative ion dryer employs innovative negative ion generation technology to neutralize static electricity and make hair smooth and shiny. These negative ions synergistically interact with the positive charges in the hair, suppressing hair breakage and tangles for three weeks, leaving hair smooth and easy to comb. Furthermore, negative ion particles effectively regulate moisture balance, penetrating from the cuticle to the inside of the hair, improving concerns such as hair stiffness, dryness, split ends, and lack of shine. 【High Airflow Fast-Drying Dryer・22m/s・110000RPM】This high-performance brushless DC motor reaches 110,000rpm in just one minute, achieving a high wind speed of 28m/s, instantly blowing away hair moisture. It speeds up hair drying. The AQielev dryer offers superior stability and durability compared to conventional products. It also features a 360° rotating nozzle and a flat outlet, concentrating the wind for faster drying, allowing you to quickly dry your hair in the morning and start your day well. 【NTC Temperature Sensor/Overheat Protection】The dryer has a high output of 1200W and is equipped with an NTC temperature sensor, which automatically and efficiently adjusts the power of the heating element to maintain a uniform temperature at each dryer outlet. There is no sudden temperature rise when drying your hair with the dryer, effectively protecting your hair at a stable temperature, reducing hair loss and damage from overheating, and protecting the shine of your hair. In addition, this dryer has an overheat protection function, which automatically stops if the temperature rises during prolonged use, reducing the risk of accidents and increasing safety. 【3 Wind Temperature Settings & 2 Wind Speed Settings】This dryer is multi-stage adjustable, with 2 wind speed settings and 3 wind temperature modes (cool, warm). By pressing the temperature adjustment button, the light changes color according to each temperature (cool air is green, warm air is orange, and hot air is red), making the temperature easy to see at a glance. Of particular note is the ability to manually adjust the wind speed.
