When the largest particles are passing via this pathway, the bundles of fibers behave similar to a kitchen area sieve which bodily blocks the particles from passing as a result of. Nonetheless, when smaller sized particles move Together with the air, given that the air twists and turns, the lesser particles can't keep up With all the movement of your air and thus they collide Using the fibers.

The idea at the rear of the development of your HEPA filter was born from gasoline masks worn by troopers fighting in Earth War II.

The British Army Chemical Corps duplicated this and started to manufacture it in substantial portions for their own personal service gasoline masks.
