What are the harmful eects of PM2.5? According to the EPA, PM2.5 poses the greatest risk to a person's health. ese particles can embed themselves deep into your lungs, and some may even get into your bloodstream. e HEPA lters installed in professional laser fume extractors have an eciency rat- ing of 99.999% at 0.3 microns. is means that it removes 99.999% of the most aero- dynamically penetrating particles, known to be 0.3 microns, while smaller and larger particles are even more eectively captured, resulting in extremely clean air free of respi- rable dust. Without this type of lter, your lungs will be completely exposed to these deep penetrating particles. VOCS Volatile organic compounds (VOCs) are compounds that have a high vapor pres- sure and low water solubility. VOCs are emitted as gas molecules from certain solids, liquids, or when a laser burns the target material. Some of these VOCs may have a wide range of short-term and long- term adverse health eects. Depending on the target material, a la- ser can generate relatively low VOCs and sometimes very high concentrations of it. In either case, the EPA's Total Exposure Assessment Methodology (TEAM) stud- ies have found that elevated concentra- tions can persist in the indoor air long after the activity is completed. It is un- derstood that these VOCs can accumu- late in a room without proper gas phase ltration. Proper laser fume extractors have gas lters that contain substantial amounts (15-80 lbs.) of activated carbon blends to adsorb and treat the VOCs in the air- stream.
