At present, with haze weather affecting a large number of Chinese cities every year, air quality is often subject to severe pollution. In recent years, as public awareness continues to increase, the environmental pollution with its associated harm has caused unprecedented anxiety and concern. Pollution from indoor decoration, formaldehyde, benzene, ammonia, etc., causes various degrees of damage to human body health, practical and effective purifier is becoming a necessity. On April 21, 2017 we were informed by the Shanghai Environmental Protection Industry Association that for the health of our children, "Shanghai 365 Classroom Air Detection Research Initiative" officially launched.
