Air Hygiene International, Inc.

Air Hygiene International, Inc. (Air Hygiene), is a professional emissions testing company that provides air emissions testing services. The company was founded in 1997 by Quinn and Swanson Bierman. Native Oklahomans, the brothers built the company on values that were  established growing up in rural western Oklahoma on the family farm.


Air Hygiene’s client base has grown to over 500 companies with project experience in all 50 states, Mexico, Canada, Bolivia, UAE, Singapore, Trinidad & Tobago, South Korea, and Qatar.  Air Hygiene’s primary clients are leaders in providing power and energy to the world. Demand for our testing services has more than doubled for six consecutive years. With marquee projects including testing on the world’s largest gas fired combustion turbines and the largest power plant in the United States, we are at the fore-front of the emissions testing and stack testing for the power industry.


Air Hygiene’s ultimate reason for growth and success is best defined by the people who work here.  Our project managers ensure every client receives customer care from the beginning to the end of their projects. Quality, service oriented emissions testing remains our primary focus as we move forward.
