Reaction to New CDC Ventilation Targets in Light of COVID

The Centers for Disease Control and Prevention just updated its ventilation guidance on helping prevent indoor transmission of the virus that causes COVID. It includes a recommendation to get at least five air changes per hour of clean air in occupied spaces.

Dr. Joseph G. Allen and other experts have been advocating for this guidance even before the pandemic. He’s the associate professor and director of the Healthy Buildings Program at the Harvard T.H. Chan School of Public Health.

Dr. Allen tells “Conversations on Health Care,” that “Making indoor air healthier came into the mainstream during the COVID-19 pandemic. New ventilation targets from the CDC are a key advancement of that work and are a historic public health achievement that can help normalize health-based indoor air quality standards. This new guidance can help mitigate indoor transmission of viruses like SARS-CoV-2 and influenza, and also help against other airborne hazards such as wildfire smoke and allergens.”

Hosts Mark Masselli and Margaret Flinter talked to Dr. Allen last year and we’re sharing the episode again to highlight these important issues.
