Campus air sterilizer manufacturer Bager believes that a school is a place where children have lived for a long time. Its attributes are crowded, and the immune systems of different grades and ages are different, and the situation is complicated. As long as there is trouble outside, the entire classroom becomes a "hardest-hit area". One person infects many people, which is the most headache. In winter, the indoor doors and windows are closed, the air quality cannot be improved, and the disease is very easy to recur. Today I will tell you about the necessity of campus air sterilizers.

Defense against tiny particles such as PM2.5

According to the research results of the School of Architecture of Tsinghua University, when the doors and windows are closed, the indoor PM2.5 concentration is about 1/2 to 2/3 of the outdoor, and this part of the particles is mainly concentrated in the particle size of 0.1 microns to 1 micron The range, that is, the small and toxic particles in the outdoor pollutants will enter the room. The average primary and secondary school classrooms have many windows, and the airtightness is not as good as that of residential buildings, and the indoor pollution is even more serious. In addition, compared with adults, the respiratory system of teenagers and children is more susceptible to the influence of PM2.5, resulting in respiratory problems such as coughs and colds. Students spend one-third of their day in school. In an environment with high PM2.5 concentrations, the incidence of respiratory diseases increases significantly, and they are prone to chronic respiratory diseases in the long run. This shows the necessity of campus air sterilizers.

Defense against germs and bacteria

The classrooms of primary and secondary schools are small and the students are dense. In winter and spring, infectious diseases such as influenza and chickenpox are most likely to break out on a large scale. Shanghai once conducted air monitoring on 8 primary and secondary schools in Fengxian District, and found that the total number of air bacteria in the classroom was 0.2/cm2 before class, and rose to 1.8/cm2 after the fourth class. If the classrooms are poorly ventilated, and a large number of germs produced by students' coughing and sneezing will accumulate and spread, one person will get sick and many people will be infected.

Remove organic pollutants such as formaldehyde

School painting and decoration and replacement of desks and chairs are generally carried out during winter and summer vacations to accelerate the volatilization of pollutants such as formaldehyde and TVOC. However, the diffusion and volatilization of such pollutants will not end suddenly at a certain point in time. The volatilization process is very long. For a long time after school starts, the pollutants are scattered in the air, causing children to develop dermatitis, asthma, allergies, and headaches. When the poisoning symptoms reach a certain level, the pollution will even cause irreversible damage.

Reduce carbon dioxide levels

Campus air sterilizer manufacturer Bager believes that on haze days, winter and summer, classroom doors and windows are usually closed, classrooms are densely populated, air circulation is slow, and carbon dioxide is easy to accumulate after being exhaled. When the carbon dioxide concentration exceeds 1000ppm, the human body will feel irritable, dizzy, short of breath, and unable to concentrate.
