Indoor Air Quality Standards and Practices

The video discusses the importance of indoor air quality, especially in the context of COVID-19. It highlights the role of ventilation, filtration, and air disinfection in reducing airborne pathogens. The video also covers the standards set by ASHRAE and the need for better regulation and investment in indoor air quality. Practical solutions like source control and the use of HEPA filters are explained, along with the importance of ensuring equitable access to clean air.
