While AAF is an international company, our global headquarters remain in Louisville, where it was founded in the 1920s. Bill Reed, a skilled engineer and entrepreneur, developed the Reed Air Filter in 1921. This creative filter solution for the automobile industry established the foundation for what is today a global leader in air filtration. His concept was so successful, Reed joined forces with seven other firms to create American Air Filter Co. in 1929. Major company milestones include providing filters for 21 types of Allied aircraft during World War II, and supplying environmental control equipment for underground launch sites and control centers for ballistic missiles during the 1960s.
A pioneer in clean air innovation for nearly 100 years, AAF International is just getting started. With our combined resources and expertise, we will continue to lead global initiatives that increase productivity, improve processes and protect public health for the next 100 years.
