The HEPA filter is one in the category of absolute filters:

"1940s: Absolute filter

The first "Absolute" filter was designed by the research and development firm Arthur D. Little (ADL) under a
classified government contract to solve a top-secret critical need at the Manhattan Project, where the first
atomic bomb was developed during World War II. The need: to find an efficient and effective way to filter
radioactive contaminants from the air. With 99.95% efficiency on 0.3 micron particles, the Absolute high
efficiency particulate air (HEPA) filter was a major step forward in air filtration technology. By 1950, the
Absolute was declassified, and ADL and Carrier Corporation formed the Cambridge Corporation in
Syracuse, N.Y. to market the product commercially. The Cambridge Filter Corporation was spun off as an
independent company in 1954. After purchasing Cambridge in 1991, Farr Company acquired its HEPA
filtration technology and became the manufacturer and marketer of Absolute filters."
