There are many different technologies and media in air purifiers that enable it to provide clean and safe air to users. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructured photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Synthetic fibers, HEPA high-efficiency materials, negative ion generators, etc. Most of the existing air purifiers are composite types, that is, a variety of purification technologies and material media are used at the same time.

What are the main uses of air purifiers:

1. Air purification and disinfection in hospital consultation rooms, wards, and operating rooms, to create a sterile and healthy hospital environment, and effectively promote the recovery of patients after illness.

2. Air purification and disinfection in schools, classrooms, crowded places, and closed environments can effectively block the spread of viruses in closed environments, reduce the risk of influenza and other virus infection, and protect the physical and mental health of teachers and students.

3. In closed scenes with strict air requirements, such as sterile workshops and food production lines, the use of air purifiers can effectively absorb particulate matter, dust in the air and purify viruses and bacteria that are invisible to the naked eye, greatly improving the quality of products and work. staff productivity.

4. In restaurants, hotels and other public places with a large number of people and high mobility, air purifiers can effectively purify and disinfect the ambient air and reduce the risk of infection under the epidemic.
