HEPA
HEPA stands for High Efficiency Particulate Air. It is a type of air filter that is capable of trapping 99.97% of particles that are 0.3 microns in size or larger. In aviation, HEPA filters are commonly used in aircraft ventilation systems to improve air quality and reduce the spread of airborne diseases. These filters are particularly important in the context of the COVID-19 pandemic, as they can help to prevent the transmission of the virus on board aircraft. HEPA filters are also used in other areas of aviation, such as in ground support equipment and in airport air quality monitoring systems.
