Year Founded:


Air Hygiene International, Inc. (Air Hygiene), a professional service company providing air emission testing services, was formed by brothers Quinn A. Bierman, President and R. Swanson Bierman, Vice-President in January 1997. Native Oklahomans, the brothers founded the company on values that were established growing up in rural western Oklahoma on the family farm.

Air Hygiene’s original office was a 400 square foot back bedroom and garage. Still, Air Hygiene performed services representative of a much larger company by embracing the rapidly changing field of computer and instrument technology. Efforts were made with the first testing laboratory to use the newest, cutting edge hardware, software, and instrumentation.

Air Hygiene was established to provide testing services for combustion turbines and engines. Air Hygiene began testing natural gas fired turbines and engines across Oklahoma, Kansas, Texas, Missouri, Colorado, and Wyoming. The first year of business included over 200 natural gas fired engines tested with the original Air Hygiene mobile testing laboratory. As 1998 approached, Air Hygiene expanded its client base to include the power industry; testing natural gas fired combustion turbine generators.

In the past 15 years, Air Hygiene has added over 50 employees, 30 combustion testing laboratories, regional offices in Fort Worth, TX and Shreveport, LA, testing personnel in Houston, TX, Austin, TX, and Chicago, IL, and remote locations in Las Vegas, NV and Pittsburgh, PA. Air Hygiene’s client base has grown to over 400 companies with project experience in all 50 states, Mexico, Canada, South America, Dubai, Malaysia, and Qatar. Air Hygiene has now conducted over 25,000 emission tests.

Air Hygiene is known for providing a customer driven approach to every testing job, which often includes 24-hour testing, rush on-site analysis and reports, and the highest quality testing data available. Our clients are frequently under high pressure to complete large dollar projects on-time, and Air Hygiene strives to ensure they meet these deadlines, with Second-to-None (2-2-0) testing services.
