The development of social economy and science and technology has brought great convenience to our life. Nowadays, various high-tech products are widely used in people’s life and production, which has brought great help to our life and production. Do you know anything about the products that are used in industry or household life today? Xiaobian now to introduce to you the medical knowledge of air purifier.
Medical air purifier is developed and designed according to medical treatment and laboratory environment. Medical air purifier is mainly aimed at the hospital departments, wards and other places of the environment adsorption, filtration of small particles in the air, bacteria, viruses, microorganisms and other harmful pollutants (special name “harmful aerosol”), dynamic continuous purification of indoor air; In addition, for laboratories, clean rooms and other high clean environment places, can maintain and improve the cleanliness of indoor air, has reached the air environment requirements of high cleanliness. Medical air purifier, also known as medical air purifier/medical air disinfection machine/medical aerosol adsorber.
Originally used for nuclear research protection, HEPA is now widely used in precision laboratories, medical manufacturing, atomic research and surgery, where high cleanliness is required. HEPA is made of very fine organic fibers interwoven, the ability to capture particles is strong, small pore size, large adsorption capacity, high purification efficiency, and has water absorption, for 0.3 micron particles cleaning rate of 99.97%. That is, only three out of every 10,000 particles can penetrate the HEPA filter. Therefore, its filtering effect of particulate matter is very obvious! If you use it to filter the smell of cigarette smoke, the filtering effect can be almost 100 percent, because the particles in cigarette smoke are between 0.5 and 2 microns in size and cannot pass through the HEPA filter membrane.
Medical H13 grade HEPA+ antibacterial composite screen was used. Can effectively filter 0.3 μm (three millionths of a meter) of tiny solid suspended matter, commonly known as PM0.3. PM0.3, also known as particulate matter that can enter the lungs, is different from the well-known PM2.5, which is often rich in a large number of toxic and harmful substances and can stay in the atmosphere for a long time, and can be dispersed over 1,000 kilometers. More frightening is that PM0.3 can cross the lung blood barrier, directly into the blood, because the smallest cell platelet diameter of the human body is about 2.5 microns. Therefore, it has great influence on human health and atmospheric environment quality. It should be reminded that the HEPA filter screen has a life span. When using the air purifier, the filter screen should be replaced in time to avoid health risks.
