The new air system in modern society, is a high quality of life for the pursuit of wind chassis size, is the most effective solution to air pollution, I believe that in the near future, new wind ventilators will enter every household. The difference between fresh air ventilator and air purifier: air purifier is a closed loop type device wind chassis, can only reduce the indoor air of certain hazardous substances in air box is installed, you can not reduce the concentration of carbon dioxide can not be supplemental oxygen wind chassis, also can not meet the IAQ (indoor air quality) for fresh air requirements. Fresh air ventilator is an open circulatory system, can provide enough fresh air for the interior to protect the people in the room to breathe fresh, clean air. At the same time, fresh air ventilator wind through old and new replacement, reducing the content of harmful substances in indoor air, in large part also had the effect of air purification.
