Hepa filter is the core component of biosafety cabinet, which is composed of randomly arranged fiber mats. HEPA filter is a treatable dry high efficiency air filter, which is made of laminated boron-silicon microfibers. The key factors affecting this function are fiber density and diameter and filter thickness.
HEPA filtration system for general medical use also uses high-energy ultraviolet module to kill viruses and live bacteria in the filter medium. Some HEPA filters have a rated HEPA unit efficiency of 99.995% and are used to control diseases spread by bacteria, viruses or other harmful particles in the air.
High efficiency particulate air filter
The original HEPA filter was designed and used in the Manhattan Project in the 1940s to prevent the diffusion of radioactive pollutants in the air. It was commercialized in 1950s. The original term became the registered trademark of A, and a common term was a very efficient filter. ?
The specified value of HEPA filter is applicable to all very efficient air filters that can obtain the same filtration efficiency performance standard and minimum value, which is equivalent to the latest NIOSHN 100. The US Department of Energy (Doe) has specific requirements for HEPA filters in the specified applications of Doe.
