Classroom Clean Air Alliance Launches to Improve School Air

The Center for Green Schools at the U.S. Green Building Council and Inspired Air Fund have launched the Classroom Clean Air Alliance. The alliance released a Classroom Air Purifier Target Product Profile for in-room mechanical filtration devices.

Why it matters

Children spend roughly 1,000 hours per year in school buildings, and an estimated 36,000 schools nationwide need major HVAC upgrades. The alliance says current in-room air cleaners are often too loud, bulky, costly to maintain, and easy to switch off, limiting sustained use.

The alliance's findings draw on listening sessions with 26 participants serving more than 1.2 million students, while an estimated 36,000 schools nationwide need major HVAC upgrades. The stub does not state how many devices will meet the profile or what their costs will be.

The players

Center for Green Schools at the U.S. Green Building Council

The Center for Green Schools is the education-focused arm of the U.S. Green Building Council, which promotes sustainable building design and certification.

Inspired Air Fund

Inspired Air Fund is a program of Renaissance Philanthropy that supports efforts to improve indoor air quality.

The details

The alliance convened listening sessions with district facilities and operations leaders, educators, and indoor air quality researchers and practitioners. Its Target Product Profile combines school-based experience with published research, existing standards, and guidance, and it invites schools and districts to join the Classroom Clean Air Call-to-Action.

Health Landscape

The alliance builds on the pandemic-era deployment of in-room air cleaners in U.S. schools, which were rushed into classrooms in 2020. Its effort targets the practical barriers, such as noise, bulk, and maintenance costs, that limited how long those devices stayed in use.

For students and staff with asthma or other respiratory conditions, cleaner classroom air could reduce exposure to particles that trigger symptoms. The alliance's target profile emphasizes devices that are quiet, affordable, and easy to run daily, which may make consistent use more realistic.

The takeaway

Schools considering in-room air cleaners may weigh noise, maintenance cost, and daily ease of use alongside filtration performance. Joining the Classroom Clean Air Call-to-Action is one way districts can engage with the alliance's work.
