In 1962, Willis Whitfield built a room that continuously swept dust away with filtered air; the idea became essential for computer chips, NASA and modern electronics

Willis Whitfield's innovative cleanroom concept emerged at Sandia National Laboratories to combat contamination issues in engineering. By introducing a system of filtered air that flowed continually, he created cleaner workspaces, profoundly impacting semiconductor manufacturing, pharmaceuticals, and space endeavors. His approach dramatically lowered airborne particle concentrations, establishing a new standard for contamination management that influences practices today.
