HEPA (High efficiency particulate air Filter), which means high-efficiency air filter in Chinese, is a filter that meets the HEPA standard. The efficiency of 0.1 microns and 0.3 microns reaches 99.7%. The characteristic of the HEPA network is that the air It can pass, but small particles cannot. It can remove particles with a diameter of less than 0.3 microns (1/200 of the diameter of a hair) and has a removal efficiency of more than 99.97%. It is the most effective filtering medium for pollutants such as smoke, dust, and bacteria. HEPA is divided into five materials: PP filter paper, glass fiber, composite PP PET filter paper, melt-blown polyester non-woven fabric and melt-blown glass fiber. Features: large wind resistance, large dust holding capacity, high filtration precision, can be processed into various sizes and shapes according to customer needs, and suitable for different models. It can remove more than 99.7% of particles with a diameter of less than 0.3 microns (1/200 of the diameter of a hair) and is the most effective filtering medium for pollutants such as smoke, dust, and bacteria. (Smoke particles produced by smoking are 0.5 microns in diameter).
It is internationally recognized as the most efficient filter material. It has been widely used in high clean places such as operating rooms, animal laboratories, crystal experiments and aviation. HEPA high-efficiency filters can be widely used in the air supply terminals of air conditioning in dust-free purification workshops in industries such as optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments, beverages and food, PCB printing and other industries. High-efficiency and ultra-HEPA high-efficiency filters are used at the end of the clean room. Their structural forms can be divided into: high-efficiency with partitions, high-efficiency without partitions, high-efficiency high-air volume, ultra-HEPA high-efficiency filters, etc. There are also three types of HEPA high-efficiency filters, one is a super HEPA high-efficiency filter, which can purify 99.9995%. One is an antibacterial high-efficiency air filter without partitions, which has an antibacterial effect and prevents bacteria from entering the clean workshop. The other is a sub-HEPA high-efficiency filter. It is cheap and used to be used in purified spaces with low requirements.
