Company History

Air Hygiene International, Inc. (Air Hygiene), a professional emissions testing company providing air emissions testing services, that 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 emissions 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 23 years, Air Hygiene has added over 70 employees, 40 mobile testing laboratories, 50 isokinetic testing trains, along with expansion to regional offices in:

  • Phoenix, AZ
  • Chicago, IL
  • Shreveport, LA
