Interactive School Ventilation Tool
This tool is designed for building managers or school administrators who are familiar with the school’s current ventilation systems.
Small particles that people breathe out can contain virus particles, including the viruses that causes COVID-19 and influenza (flu). Good ventilation, along with other preventive actions, can help prevent virus transmission in schools.
How can I decrease the level of particles during the school day?
Select the options below to see how particle levels change as you adjust ventilation settings.
The risk of getting COVID-19 varies according to individual susceptibility and the number of virus particles to which a person is exposed. The fewer virus particles in the air, the better.
This tool does not contain all scenarios. However, you can layer strategies for even better ventilation results.
