Air Cleaning and Evacuation Devices

Air cleaning and evacuation devices have been employed to reduce aerosols and splatter distribution during dental procedures. Studies have shown that the use of HEPA-filtered extraoral suction units and other portable air-cleaning technologies can reduce dental aerosols.^113-115 Further, this reduction is enhanced when such extraoral suction devices are utilized in conjunction with traditional high-volume intraoral evacuation.¹¹⁶ It has also been demonstrated that HVAC features, including relative humidity, may also impact viral particle survivability.¹¹⁷
