What is the minimum efficiency rating for medical air filters at 1 micron?

The minimum efficiency rating for medical air filters at 1 micron is set at 98%. This standard is crucial in ensuring that medical air systems effectively remove airborne particulates, including bacteria and other contaminants that can impact patient safety and health. Filters that achieve this efficiency are essential in healthcare settings, as they help maintain a sterile environment, especially in areas such as operating rooms and intensive care units where vulnerable patients are treated. The high efficiency in trapping particles at this size is particularly significant because many harmful microorganisms fall within the 1 micron range, thus ensuring a higher level of air quality and reducing the risk of infections.
