“The Centers for Disease Control and Prevention suggests dentists consider using a portable air filter that meets the high-efficiency particulate air standard while performing aerosol-generating procedures and immediately afterwards. In its Interim Infection Prevention and Control Guidance for Dental Settings During the COVID-19 Response, updated May 19, the CDC states using a filter will reduce the particle count in the room, including droplets, as well as the air turnover time provided by the building HVAC system alone. . . while some practices may have portable filters dentists can place in different parts of the operatory, others may have filters that are part of their ventilation system. Comparing the two is hard to do because both come with their own specifications, Dr. Kumar said. While portable filters allow dentists to control their placement, their capacity may not be as large as the ones that are built into the ventilation system. “
