Which is safer, the key components of the air disinfector or the air purifier

　　The key components of the air disinfection machine are the circulating fan, the filter element and the UVC lamp. The air disinfection machine is a machine that disinfects the air through the principles of filtration, purification, and sterilization. In addition to killing bacteria, viruses, molds, spores and other so-called sterilization, some models can also remove formaldehyde, phenol and other organic pollutants in the indoor air, and can also kill or filter pollen and other allergens. At the same time, it can effectively remove the smoke and smoke generated by smoking, the bad smell of the bathroom, and the human body odor. The disinfection effect is reliable, and the air disinfection machine can be disinfected under the condition of human activities, so as to realize the coexistence of man and machine. Air disinfection is an important measure to prevent hospital infections. Using an air disinfector can effectively clean the air in the operating room, purify the operating environment, reduce surgical infections, and increase the success rate of surgery. Suitable for air disinfection in operating rooms, treatment rooms, wards and other spaces

　　There are many types of air disinfection machines, and there are many principles. Some use ozone technology, some use ultraviolet lamps, some use filters, some use photocatalysis, and so on.

　　1. Primary effect filtration, medium and high efficiency filtration, electrostatic adsorption filtration: effectively remove particles and dust from the air in the micro-air purification and disinfection device.

　　2. Activated carbon net: deodorizing function.

　　3. Photocatalyst network

　　Antibacterial net assists disinfection. Generally, nano-level photocatalyst materials (mainly titanium dioxide) are used with the irradiation of a violet lamp to produce positively charged "holes" and negatively charged negative oxygen ions, "holes" and water in the air on the surface of titanium dioxide. The steam combines to produce strong alkaline "hydroxide radicals", which decompose formaldehyde and benzene in the air, turning them into harmless water and carbon dioxide. Negative oxygen ions combine with oxygen in the air to form "active oxygen", which can be divided into wall-mounted disinfection machine to decompose the cell membrane of bacteria and oxidize virus proteins, and achieve the purpose of sterilization, detoxification and decomposing harmful gases.

　　4. Ultraviolet rays

　　Achieve the inactivation of bacteria in the air. The closer the UV lamp is to the object to be disinfected, the more bacteria will be killed and faster. In the range of ultraviolet radiation, the mortality rate of bacteria can be guaranteed to be 100%, and no bacteria can escape.

　　From the comprehensive comparison of professionalism, safety, disinfection effect, user experience and cost-effectiveness, I personally prefer air disinfection machines. Air purifiers are already bad, especially some traditional home appliance brands of mobile disinfection machines are now doing everything. Naturally, it is difficult to achieve everything by doing everything. I don’t recommend buying such brands of air purifiers. Some air purifiers also have secondary pollution after adsorption saturation. But the air disinfection machine is different. In addition to the production enterprise sanitation license and the dust-free production workshop, its disinfection technical specifications and sterilization standards are also very strict, and it is better than air in terms of quality, function, technical testing, and production technology. filter.
