The bill amends Chapter 16-21 of the General Laws, titled "Health and Safety of Pupils," by introducing a new section, 16-21-43, which focuses on school air quality. It mandates the Department of Health to establish recommended standards for indoor air quality in schools, including thresholds for temperature, humidity, carbon dioxide, and particulate matter (PM2.5 and PM10). The Department of Education is tasked with creating a program for uniform inspections and evaluations of indoor air quality within each school building, which must be conducted every five years in collaboration with local school boards. The inspections will assess various factors, including measurements of temperature, humidity, carbon dioxide, PM2.5, and PM10, as well as the efficiency of HVAC systems.

Furthermore, the bill requires that all schools with HVAC systems install filtration that achieves a minimum efficiency reporting value (MERV) of 13, where feasible, and mandates that all HVAC repairs, upgrades, or replacements be performed by a skilled and trained workforce, with adjustments made by qualified adjusting personnel. The results of the inspections and evaluations must be made easily available online and communicated directly to each school's principal, the Department of Elementary and Secondary Education, and the appropriate local school board. The Departments of Health and Education are authorized to promulgate rules and regulations necessary to implement these provisions. The act will take effect upon passage.
