1921: Reed Air Filter Invented

A century ago, engineer-entrepreneur Bill Reed invented an air filter, solving the problem of factory dust settling on his freshly painted Model T cars. After gaining the attention of Henry Ford, Bill started selling filters to every paint shop in the country. He made more money selling filters than painting cars and the Reed Air Filter Company was born.

1932: Improving Industrial Age & WWII Factories

AAF met the industrial boom head-on with the Type D RotoClone, a revolutionary breakthrough in dust control. With the onset of World War II, manufacturing facilities retooled to produce machinery and equipment for wartime needs. AAF equipped these production plants with industrial filtration systems, protecting factory workers and their critical processes.

1969: Equipping the Apollo 11 Lunar Module

The 60s brought space travel, along with the need for new clean air solutions. NASA sent the Lunar Module to the moon equipped with AAF-supplied filters to prevent contamination of the moon with particles brought from earth. To this day, we still provide HEPA filters for the International Space Station.

1999: Enabling Smartphone Innovation

Producing microtechnology requires a clean room environment. AAF International developed PTFE filters in tandem with Daikin Industries that enabled microelectronic development. These filters played a valuable role in protecting the microchips being produced for computers and early generation cellphone technology.
