However, from the perspective of health, three-dimensional, scientific and sustainable home respiratory environment, the air purifier that simply purifies PM2.5 or assists in removing formaldehyde and removing odor has great limitations. This is due to the operating principle of the air purifier itself and natural internal circulation deficiencies. As is well known, air purifiers are not capable of purifying carbon dioxide exhaled by the human body. Therefore, the air purifier can only solve indoor air for a short time, and cannot thoroughly improve the air quality in the living space. In addition, in places with concentrated population, such as kindergartens and schools, the people are high in density, high in mental consumption and long in indoor residence time, and good indoor air quality is a necessary condition for ensuring intelligence development and healthy growth of children. This requires a fresh air purification device having ventilation and ventilation functions, PM2.5 purification functions, and bacteria removal functions.
