Heating, Ventilation, and Air Conditioning Products Design Flo Desktop Fan by Soyoung An Flo is a compact and minimal desktop fan that can use regardless of the seasons. The delicate temperature setting is easy and intuitive with a stick controller on Flo's back. By adjusting the controller between heating and cooling, users will find the desired temperature. Flo also thinks about the earth and its users. Flo's built-in filter can be washable several times and semipermanent. And the filter purifies the air removing dust and viruses. Dust on a fan is the cause of respiratory disease and fire. But Flo promises clean and dust-free air for users' healthy lifestyles.
