Aerosol transmission drives the spread of many infectious diseases, including COVID-19, influenza, measles, and RSV. Improvements to indoor air quality (IAQ) through enhanced air filtration, system maintenance, and ventilation are crucial for preventing the spread of these and other emerging diseases, as well as reducing contaminants in indoor air. The benefits of good IAQ extend beyond infectious diseases to help reduce the incidence of chronic conditions like asthma and even lower the risk of certain cancers and complications of cardiovascular disease. Improvements to bolster IAQ are often neglected, even though most people spend an average of 90% of their time indoors.
In December 2022, the Center for Health Security began work with the Center for Public Health Law and Policy at Arizona State University to develop a model law for consideration by state legislatures to help improve IAQ in public buildings, thereby promoting individual and communal health. The Center's IAQ Project Team drafted a blueprint outline of the Model Clean Indoor Air Act (formerly called the “Model State Indoor Air Quality Act”). On March 6–7, 2023, the team convened a National Advisory Committee of subject matter experts to vet the blueprint and share ideas on potential provisions. Committee members engaged in robust discussion of the initial premises, objectives, and blueprint for the act, providing feedback on dozens of legislative provisions. The team shared an initial draft of the model law with committee members on April 1, 2023, and released a final version on August 17, 2023.
