This idea has potential. Especially if you can work in with the Asthma Foundation. They have done a documentary on clean air in homes, donated air purifiers to a school and have a National Respiratory Strategy https://www.asthmafoundation.org.nz/our-work/advocacy/national-respiratory-strategy

Maybe someone in your team can contact the Asthma and Respiratory Foundation NZ and work together to push for change in schools + building codes. They look to be pushing for the same outcomes.
