COVID-19: Improve ventilation by opening windows

With described video



A vertical line divides the video screen in two.

On both sides of the screen a breathing manikin is seen in a black room wearing a shirt with the word “Canada” printed on it. A window is visible in both scenarios. Both manikins exhale respiratory particles that appear as white smoke at the same intervals.

Narration: Good ventilation can reduce the spread of COVID-19 by reducing infectious particles, which can linger in the air.

On the left side of the screen, the window is closed and smoke accumulates in the room. The text on screen says: “Window CLOSED”

On the right side of the screen, the window is open and the smoke disappears through the window. The text on screen says: “Window OPEN”

Narration: Improve ventilation in your home by opening windows and doors regularly. Even a few minutes at a time will help. Learn more about ventilation at
