The air flow varies in irregular patterns to perfectly simulate the pleasing effect of a natural breeze.With long time research and data collection on natural wind, our R&D team developed a proprietary algorithm that simulate the irregular changes of natural breeze,Xiaomi Smart Standing Fan 2 ProTraditional Standing FansecondsThe above chart shows the air velocity curve of this product in natural breeze mode. The horizontal distance between the fan and the anemometer is 2 m. The data were recorded when it operated at speed setting 1 in natural breeze mode without oscillation for one hour, among which, data for a duration of 30 seconds were used to produce the curve. The above curve is for trend illustration purposes only and actual data may vary. Data provided by Xingyue Research Laboratory.
