The Birth Of HEPA
- May 02, 2018 -

HEPA was born in the United States' three-year Manhattan project in the 1940s. It produced atomic bombs and left behind 1.4 billion U.S. dollars in property, including a 9,000-man Los Alamos nuclear weapons lab. In the “Manhattan Project,” in order to prevent the spread of radioactive contaminants in the air, researchers have developed highly efficient HEPA filter membranes, which are used in biochemical and other anti-nuclear products, and are divided into H12 to H17 and other levels. For fine particles with a diameter of 0.3 microns or more, the filtration efficiency ranges from 99.7% to 99.9999%.
