The DREO TurboCool Misting Fan 516S is the compact entry point of DREO's 2026 summer TurboCool line, a 3-in-1 personal desktop evaporative cooler that combines a fan, ultrasonic mister, and humidifier in one 48W unit. Its 1.7 MHz ultrasonic plate atomizes water into 11 μm droplets that evaporate in the 26 ft/s airstream, delivering up to 5°F / 3°C of mess-free perceived cooling from a 1.3 L tank that lasts up to 12 hours. Released in April 2026 at $99.99, it pairs a 150° oscillating brushless motor with app, voice, remote, and touchscreen control, a built-in temperature/humidity sensor with auto mist shutoff, and an RGB humidity alert ring, making it a strong desk-side alternative to Evapolar's evaCHILL for dry-climate offices and bedrooms.
