Common problems of hospital air purifiers should be paid attention to when buying

　　Hospital air purifiers can effectively kill 99.99% of Escherichia coli, Staphylococcus aureus, Candida albicans, formaldehyde, benzene, bacteria, viruses and other harmful gases in the air, and can reach Class 8 air cleanliness and Class 100,000 clean operation. Room standard, what are the common problems of hospital air purifiers?

　　1. Will it cause harm to human body when using UV air purifier?

　　Let us first take a look at the harmful effects of ultraviolet rays on medical air purifiers. Long-term exposure to ultraviolet rays can cause cell disease. The main sterilization method of common ultraviolet air purifiers on the market has used ultraviolet lamps, and each machine is placed 2 -8 different number of tubes, each tube is about 10 times the intensity of ordinary disinfected car lamps, if it is directly irradiated to the human body, it will be very harmful.

　　Therefore, most UV air purifier manufacturers will design the internal circulation mode of the air purification and disinfection device when designing related products, that is, the disinfection range is locked inside the purifier cavity, and the ultraviolet rays will not leak out. Avoid direct exposure of ultraviolet rays to the human body. Therefore, current air purifiers coexist with humans and machines.

　　2. What is the difference between a plasma air purifier and an ultraviolet air purifier?

　　The core component of the plasma air purifier is called a plasma generator. The so-called plasma generator is a device that generates positive and negative ions, mainly composed of two electrode sets wall-mounted purifiers.

　　His position is equivalent to the role of ultraviolet lamps in ultraviolet air purifiers, and plasma air purifiers use bipolar plasma electrostatic field to decompose and destroy negatively charged bacteria, polarize and adsorb dust, and combine them with drug-impregnated type Activated carbon, electrostatic nets, photocatalyst catalytic devices and other components are subjected to secondary sterilization and filtration, and a large amount of treated clean air circulates quickly, keeping the controlled environment at the standard of "sterile clean room".
