What kind of medical air sterilizer should schools install
As public health issues are increasingly valued, schools, as places where students gather, have become particularly important in managing air quality. Especially during the epidemic prevention and control and influenza seasons, schools with conditions should consider installing medical air sterilizers to improve the safety and health of indoor air. So what kind of air sterilizer should be chosen?
1. Disinfection technology
There are many air disinfection technologies on the market, including ultraviolet (UV) disinfection, negative ion generators, photocatalysts, and HEPA filtration. Schools can choose the right technology according to their needs:
Ultraviolet disinfection: UV-C ultraviolet rays can effectively kill bacteria and viruses in the air and are suitable for conventional air disinfection.
Negative ion generator: By releasing negative ions, it can attach and settle particles in the air, but when using it, it is necessary to pay attention to the combination with ventilation equipment.
Photocatalyst technology: It uses photocatalytic reactions to decompose harmful substances, which is suitable for long-term use and does not produce secondary pollution.
HEPA filtration: High-efficiency particulate air filters can capture 99.97% of particles with a diameter of 0.3 microns, which is suitable for long-term maintenance of air cleanliness.
2. Disinfection efficiency
When choosing a hospital-level air sterilizer, you need to pay attention to its disinfection efficiency. The CADR (clean air delivery ratio) value of the equipment is an important indicator. The higher the value, the greater the amount of clean air that can be produced per unit time, thereby more effectively improving the indoor air quality. Air sterilizers suitable for schools should have high CADR values to cope with the breathing needs of a large number of students.
3. Safety and environmental protection
Medical air sterilizers need to take students' safety into consideration during the disinfection process. Avoid using equipment that releases harmful gases or produces ozone. In addition, choosing products that are easy to maintain and clean can reduce the risk of secondary pollution. At the same time, try to choose low-noise equipment to ensure that students' learning environment is not disturbed.
4. Use area and applicable places
The various areas of the school, such as classrooms, laboratories, canteens and libraries, have different use areas and traffic flows, so the model and number of sterilizers need to be reasonably configured according to the specific use places. For large classrooms or gathering areas, it is recommended to use multiple sterilizers for distributed layout to ensure that the air in every corner can be effectively disinfected.
5. Scientifically cooperate with ventilation
Air disinfectors cannot completely replace ventilation. Schools should ensure that classrooms and public areas maintain good natural ventilation. If conditions permit, consider combining air disinfectors with ventilation systems to improve the overall effect of air quality.
6. The difference between air disinfectors and air purifiers
Common air purifiers can only remove particulate matter in the air, such as dust, PM2.5, etc., and cannot kill viruses and bacteria in the air, so you should choose air disinfectors that can not only remove particulate matter, but also kill viruses and bacteria. Because schools are densely populated, viruses in the air are easily spread, so disinfectors are needed to kill viruses, reduce transmission, and improve our air.
When choosing a medical air disinfector, schools need to comprehensively consider multiple factors such as disinfection technology, disinfection efficiency, safety, and area of use. At the same time, the reasonable configuration and scientific use of these devices will help improve the school's air quality and protect students' health. In today's epidemic situation, a safe learning environment is an important guarantee for the healthy growth of every student. Schools with conditions do need to choose to install suitable medical air disinfectors.
