Bi - Ionic High Speed Hair Dryer combines Bi - Ionic Technology (dual ions to eliminate static & frizz) with an 110K RPM motor for professional - grade speed. Its Spiral Air Duct (Mera’s patented design) reduces hair tangling while maximizing airflow. In Safe Mode, it delivers gentler heat for sensitive scalps; the Self - Clean mode uses reverse airflow to prevent clogs and maintain long - term performance. This hair dryer operates at a conversational volume—similar to the sound level of normal conversation—making it comfortable for everyday use without disrupting your focus. The Multi - Color Heat Indicator simplifies temperature settings, while its powerful airflow (driven by the high - speed motor) speeds up drying without sacrificing safety or comfort. Whether for daily use or professional styling, it brings salon - quality results effortlessly.
