The CAVI team is asking for your proposals and ideas to reach additional people through an expansion project across Canada. Our priorities remain the same, the sharing, learning and citizen science that has so inspired us so far. (4/5)

We have been cautious and frugal with funding from the Balvi foundation and we are in the position to expand our impact with additional CO2 monitors to distribute within Canada. As a team we wonder if our we could reach people who are unable or unlikely to access the public library programs. (3/5)

Students & their drivers deserve a safe & healthy ride to school, including clean air to breathe!

School buses have poor air filtration & ventilation systems (air quality = bad) πŸ˜”

Wearing a respirator mask (N95, KN95, etc) & opening windows (when the outdoor air is safe!) can make a difference!

Kids are breathing more toxic air in schools. We know how to fix it, but will Ontario act? With wildfires raging and measles on the rise, the air in our schools is becoming more harmful to students.

Kids should not face a "future of increased exposure to known threats such as wildfire smoke, COVID-19 and measles...their vulnerability would demand investment." - @flannerydean.bsky.social

This study made some waves on social media yesterday. It purports to show that CO2 concentration doesn’t correlate with covid transmission.

Let’s talk about this, I have some thoughts.

Great podcast episode on a theatre in Vancouver designed for great indoor air quality. CO2 monitors are discussed as well, a clear explainer for those just learning how devices can be helpful.
