Why am I hearing more about bioaerosols now?
Because researchers have begun to recognize them in the last five years, including the World Health Organization. The first researcher we worked with and who made the world popular is Dr. Harriet Burge with the Harvard School of Public Health. Our first encounter with her took place at an IAQ seminar in Maine in 1986 wherein we were both on the speaker list. Her contention was and is the bioaerosols account for a larger portion of our IAQ problems than commonly thought. The fact that she was right then and now is why we are in business today. • Why are bioaerosols such a problem now? There are two dominant reasons why we find more microbial activity today then in years gone by. First is time clock operation wherein A/C systems are shut down to conserve energy. This can be from 8 to 12 hours per day and usually the entire weekend. During these periods the coil and drain pans are wet or at least damp and the ambient temperatures near perfect for accelerated microbial growth. Second is VA
