HEPA Filters and More
Before today, I didn’t know a whole lot about HEPA filters. I received a good education from Bob and Gail Brandys from Occupational and Environmental Health Consulting Services. “Dr. Bob” has over 30 years of experience in the safety and environmental field, and Gail, for over 25 years, has been involved in safety and health consulting for industries and institutions.
The interview discussed particle sizes, different types of HEPA machines, HEPA performance, and some procedures on taking air particle counts with a laser particle counter.
We also discussed Bob and Gail’s involvement with Indoor Environmental Standards Organization (IESO). They’re working on 10 standards that focus on indoor air quality, which include mold counts, electromagnetic fields, and other harmful particulate for homes, schools, and other institutions.
You can find more information on the IESO website, www.indoorstandards.org.
