By the 1990's, Clean Air Systems had established itself as the premier indoor air quality expert in the hospitality and recreation industries in the Western United States. We had a large client base of smaller gaming operators such as card rooms and bingo facilities in Washington, Oregon, Idaho, Montana, and Alaska.

Since the founding of our company 35 years ago we have constantly searched for better ways to deliver optimum results for our clients. We were also seeking ways to provide the same service for bigger smoking-related businesses, particularly large casinos. In developing the Casino Air product line, we had three main goals:

• The technology has to work better than anything else.

• The technology has to be invisible to the customers, which means it has to integrate into the existing HVAC system.

• The technology has to be as simple as possible to own and operate.

By the mid-1990's we had identified the basic technologies we were going to use and company president Randall Dodd began doing the research and working with potential manufacturers to adapt the basic technologies for use in large gaming environments.

Twelve years, 75,000 pages of research and more than 150 clients later, Casino Air is the international leader in providing integrated solutions to remove tobacco odor and visible smoke from casinos of all sizes. In conjunction with integrating our technology, we've also become expert in casino HVAC systems design, operation, maintenance and troubleshooting. Casino Air division leader and Clean Air Systems president Randall Dodd has gained worldwide recognition for his pioneering efforts in this field and has published two scientific papers on tobacco smoke and odor control in gaming environments.
