A century ago, it all started with engineer and entrepreneur Bill Reed who invented an industrial air filter to solve the problem of factory dust settling on freshly painted cars. That was the very start of AAF and from that moment on we have continued to progress and now have facilities in 22 different countries.
Air filters proved vital across a whole host of other industrial, commercial, and residential applications. Look back over our rich history and learn how the business adapted as the demand for clean air continued to grow.Learn more
