Many hospitals use various types of air sterilizers. Most of them use nurses and doctors who only know the operation, but do not know the internal working state, and do not know what device is selected for filtration. The old driver who has been engaged in the sales of medical air disinfection machines for many years takes you on the train. From the aspect of purification technology, I understand the working principle of the air disinfection machine. The filtration technology used by the medical air disinfection machine.

1. The high-efficiency filter is mainly used to filter a small amount of remaining suspended particles, and the service life is about half a year, which needs to be replaced regularly.
2. The adsorbent material layer is used to absorb most of the odorous substances in the air or the gaseous organic pollutants caused by decoration, etc. The active substance of this layer is activated carbon, and the service life is basically in one quarter, remember to replace it regularly.
3. The coarse filter is used to block the large amount of flying dust in the air. It can be used repeatedly after washing with water.
4. Photocatalytic technology, through the ultraviolet catalysis, the bacteria, dust mites, odors and gaseous pollutants that have not been filtered out by other filter layers are reacted into other non-hazardous substances, and the concentration of the original harmful substances is minimized. This unit has a service life of approximately 2 years. Many products labeled "photocatalyst" means that it has a photocatalytic reactor filter.
5. Activated carbon filter is used to filter the ozone associated with the electrostatic precipitator mentioned above. At the same time, some odor and organic gaseous pollutants can be removed by chemical reaction, which can be used for about one and a half years. .
6. The electrostatic dust collecting device is used to collect suspended small particles. After using for a period of time, it needs to be cleaned with a soft brush and disinfected with alcohol, which can be used repeatedly.
At present, some medical air disinfection machines that are marketed do not necessarily use these air purification technologies, and some companies independently innovate, such as Weiyi's research and development of semiconductor air disinfection technology, which greatly improves the colony rate and the service life of the machine. For the majority of users.
