Our History

From what now seems to be our modest beginning back in 1939, providing simple filter cleaning and replacement services, National Air Filter has developed into one of the nation's largest independent, full-service Quality Air Management companies. As a medium size company, in over 70 years of serving our customers, NAF has had the rare opportunity to experience both a rich and colorful history.

During the past 20 years, NAF has played a significant role in supporting pharmaceutical manufacturing facilities with FDA approved products and GMP-compliant services. With time, NAF's reputation for exceptional service expanded through the past decade's leading growth industries, including Devices, Diagnostics, Biotech, Healthcare and Research, Power Generation, and Commercial Real Estate.

Today, NAF remains the industry leader for reliable, efficient, and compliant cleanroom air.
