We are not alone in our support of the use of airflow management tools for engineering controls, as well as airflow visualization products to verify airflow patterns and identify turbulence in indoor environments such as restaurants, classrooms, and manufacturing facilities. FDA guidance discusses the importance of clean areas for drug product quality and includes recommendations for measuring air velocity, as well as in situ air pattern analysis at critical product areas.
ASHRAE statements regarding transmission of SARS-CoV-2 convey that ventilation and filtration provided by HVAC (heating, ventilating, and air-conditioning) systems can reduce the airborne concentration of Covid-19 and thus lower the risk of transmissio
Recent guidance from ASHRAE is to consider increasing ventilation rates to help protect against the transmission of COVID-19, and as a result, many are working to become familiar with an unfamiliar topic.
