Is long-term use of air disinfection machine harmful to human body?

According to the different disinfection factors in air disinfection machine, air disinfection machine can be divided into ultraviolet air disinfection machine and plasma air disinfection machine. When in use, the motor rotates to make air flow through the filter and sterilizer in the air disinfection machine. The filter is generally composed of HEPA glass fiber material and honeycomb activated carbon filter screen, while the sterilizer has ultraviolet lamp tube and plasma generator. When the ultraviolet lamp is energized, it will emit ultraviolet rays, among which the ultraviolet rays with the wavelength of 254nm have a strong destructive effect on the cell structure, and the plasma generator will produce a large number of positive and negative ions under the action of voltage. So in the process of using ultraviolet air disinfection machine or plasma air disinfection machine, will it cause harm to human body? At the same time, what should we pay attention to when using air disinfection machine for a long time? Ultraviolet air disinfection machine. Ultraviolet disinfection is a widely used disinfection method, such as tableware disinfection cabinet, water purifier and air disinfection machine. Ultraviolet rays will destroy the cell structure of bacteria, viruses and other microorganisms, and also cause harm to human skin. It is common that when our skin is exposed to the sun for a period of time, it will turn black or even fall off after a period of time, which is enough to prove that ultraviolet rays are very harmful to the body. Therefore, long-term use of ultraviolet air disinfection machine should prevent ultraviolet rays from leaking out and from irradiating the human body. Under the action of the fan, the indoor air is irradiated by ultraviolet rays in the air disinfection machine, completing the disinfection and sterilization process. Plasma air disinfection machine. Plasma air disinfection machine is a large number of positive and negative ions generated when the plasma generator is powered on. These positive and negative ions are free in the air, some of them are combined with each other, some are combined with microbial cells, and some are combined with particulate matter in the air, which produces the disinfection and dust suppression effect of plasma, and even the benefits of free are beneficial to human metabolism. In addition, when the low-voltage electricity passes through the plasma generator, it is converted into high-voltage electricity. When the molecules in the air ionize to form ions, it will generate high energy, which is enough to destroy or even smash the microbial cell bodies near the plasma generator. Therefore, plasma air disinfection machine mainly carries out sterilization and disinfection in these two forms. In a word, using ultraviolet air disinfection machine or plasma air disinfection machine has advantages and disadvantages. Pay attention to the safety of electricity use during use to prevent ultraviolet rays from leaking out. The use of air disinfection machine, especially HEPA and activated carbon filters, should be cleaned or replaced regularly to ensure the working efficiency and service life of air disinfection machine.
