Sadiq Khan plans to install air filters in 200 London schools as part of a £2.7 million trial.
The aim is to assess whether these filters could be implemented in all schools across the capital.
Schools will be chosen based on pollution levels and deprivation levels for equitable distribution.
The investment covers the cost of filters, school engagement, monitoring, and maintenance.
The filters will trap particulate matter (PM2.5) using replaceable cartridges.
The initiative has garnered support from parents, teachers, and experts concerned about the health impacts of air pollution on children.
