Dear Ms. McShane,

This letter is in response to the proposed smoking ban and the effectiveness of filtration systems on indoor air quality (IAQ) contaminants with specific regard to environmental tobacco smoke (ETS).

There are specifically designed commercially available systems that will remove the toxic and carcinogenic components of Environmental Tobacco Smoke (ETS). Such a system includes high efficiency particulate filtration along with sorbent media to remove the toxic gasses, chemicals and carcinogens. Because of the type of technologies that will be used, the system will also remove unrelated bio-aerosols, volatile organic compounds (VOC's), various gaseous hydrocarbons, mold, and viruses.

These technologies are recognized and used by the EPA and NIOSH. NASA, National Laboratories, and the Military (for protection from airborne chemical, biological and nuclear terrorists weapons), use these technologies as their main course of mitigation. Our company, Connessione Scientific (a Life/Safety Consultancy Company), is an expert in molecular (gas phase) filtration with over 20 years design experience. The technologies in question have been developed and improved over the last half century to protect human health and reduce the associated hazards. We have consulted on many systems for the removal of airborne toxic and carcinogenic materials.

With the invention of the Hepa filter at the laboratories of Los Alamos, particulate filtration took a massive step forward. Adsorbent and the newer Chemi-sorbent materials have made it possible to capture or destroy hazardous and reactive gasses with sorbent filtration, which include the toxic and carcinogenic components of ETS.

I have included six related studies that prove the effectiveness of these technologies. The primary paper I have included with this document is a joint study from the Office of Homeland Security (OHS), the Center for Disease Control (CDC) and the National Institute for Occupational Safety and Health (NIOSH) that tells how the technology that we are speaking of will actually protect building owners and occupants from chemical, biological, and radiological terrorists weapons. In other words, not only simple particulates and gasses found in ETS, but also complex multi-strain bacterium and airborne man-made toxic gasses will be captured or killed. You will also find attached a study from the University of Illinois to further demonstrate the effectiveness of the described sorbent technology for the removal of a primary class of suspected carcinogens in ETS.

Please feel free to call on us if we can be of further assistance. I can be contacted toll free at 866.405.1400 or on my cellular at 630.234.5959
