YRDSB is optimizing air quality in schools through improved ventilation and filtration. This is a key element in the protective strategies being employed to reduce the risk of COVID-19 transmission and support healthier and safe learning environments.
See below for information on ventilation in adult learning buildings, or use the links below to find your school:
| Ventilation System | Mechanical Ventilation |
| Ventilation assessed | Yes |
| Running ventilation systems longer | Yes |
| Higher grade filters installed (MERV13) | Yes |
| Increased frequency of filter changes | No |
| Increased fresh air intake (windows and/or mechanical ventilation systems) | Yes |
| Standalone HEPA** filter units deployed in portables, as needed | N/A |
| Standalone HEPA filter units in place | 1 |
*Some measures may not be feasible within the context of a school facility/site and related building systems.
