Dongyang S&T is a professional manufacturer that produces Non Motor Anion Air Purifier. People today who spend daily lives mostly in closed rooms are vulnerable to various respiratory and skin diseases, threats of yellow dust and fine particles, and so on, which raises the interest on air quality and health in closed rooms. The air outdoor has the natural purification function but the air indoor which is shut has no such self-purifying function, which increases the needs for improving the air quality. The demand for improvement of air quality in urban areas, households and closed rooms are increasing. We are proud to present ‘Air Clara,’ an anion air purifier, which generates the anion wind without a motor to be diffused in the air.
