How the Manhattan Project Gave Us Today's Air Filters

The video explains the history and development of HEPA filters, originating from the Manhattan Project. Initially designed to protect against radioactive particles, these filters have evolved to handle various air pollutants, including viruses. The video details the role of asbestos in early designs and Irving Langmuir's analysis of particle filtration. Modern HEPA filters, now asbestos-free, are crucial in many industries, offering high efficiency in trapping particles.
