The Wusen system promotes the movement of water through a high-pressure system, and then splits charged small water droplets into negatively charged surface and positively charged inner layers through the action of high pressure. The surface of negatively charged water droplets combines with atoms or molecules in the air to form negative ions. The inner layer of heavier water droplets sinks under the action of gravity, thus obtaining a large amount of negative ions in the air, forming a white mist that resembles natural mist, like a "forest of mist" in a fairyland. More than 70% of the water mist particles generated by the Hangzhou Wusen system have a diameter of less than 10 microns, which can increase air humidity to alleviate the problem of dry climate in northern regions, effectively improve air quality in northern regions, and form a comfortable and pleasant quasi Jiangnan climate. Wusen uses micro porous high-pressure impact atomization technology to instantly split water molecules into billions of 1-10 micron mist molecules, reaching a suspended state in the form of mist, completely equivalent to natural mist. Walking in between, one can feel fresh, moist and delicate air, which will not wet clothes and glasses at all.
