AAF International traces its roots to Bill Reed, a skilled engineer and clever entrepreneur who recognized in 1921 that cleaning the air was critical to the growth of society, the development of technology, and the protection of human health. He developed the Reed Air Filter which represented the initial step in building an international company that globally dominates the air filtration industry – AAF International. Today, selling under the AAF and AmericanAirFilter® brand names, AAF clean air products and systems offer the most comprehensive clean air solutions available in the world. Our products are the industry benchmarks for quality and performance, from simple roughing filters, to air pollution control, to gas containment removal, to the highest efficiency filters used in the most stringent clean environments.
