DIFFERENT STUDY, DIFFERENT RESULTS
Allen and Jerry Betsill, owners of Abbey Road Clean-Aire (predecessor to Video-Aire), wanted to know if the duct-cleaning process they were using really worked. They had read claims made by another local duct-cleaning company and realized the great tool it would have if they could show quantifiable results. "Anecdotal evidence, reports from customers, etc., supported our conviction that what we were doing was effective, and we came to believe our process could withstand the scrutiny of a formal test," recall Allen and Betsill. (Betsill later left Abbey Road to become an attorney.)
They commissioned Robert Garrison and Larry Robertson of Mycotech Biological, Inc., to design a protocol for an independent, controlled study of their duct-cleaning process. Conducted in 1990 and 1991, the study underwent an extensive, two-and-a-half year peer review process before its publication in the Annals of Allergy Medicine in 1993.
<>Assigned by editorial advisors to an anonymous panel of Ph.D.s and M.D.s, all questions and criticisms had to be answered and addressed to the satisfaction of all members of the panel. "We had invented a whole new sampling method, so it was the method itself, as well as the results, that were under review," said Robertson. This study was later endorsed as "recommended reading" by American College of Allergy, Asthma, and Immunology during its literature review course in Charleston, SC in 1995.
