The air circulation created during operation allows sweat on the skin to evaporate more quickly, thus supporting the body's natural cooling process. As a result, you achieve a pleasantly perceived indoor climate while operating the fan, even if the air is not cooled. The oscillation function increases the effective range of the fan. This is particularly advantageous when multiple people are in a room, as everyone can benefit equally from the cool breeze. Of course, you can also turn off this function if you prefer the device to supply fresh air to only a specific area.
