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

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

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.

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.
A couple of years ago I saw a post from
@mosssphagnum.bsky.social about the post-1918 flu pandemic ventilation system in the Orpheum Theatre in Vancouver. I took a visit + made a whole episode about it for Public Health is Dead! There's glitz! There's glam! There's...mushrooms and ghosts?

Fantastic!
"You can now borrow a...CO2 monitor from our Vancouver office free of charge for a maximum of seven days. By measuring CO2 levels in indoor environments, you can gain information about ventilation in a space and find opportunities to improve it. "

You can borrow one for free at many Canadian libraries. 😊
Anyone who saw my Aranet post, I worked with the company and it's on sale for 166 down from 249.
I'm kidding.
I mean it is on sale but it has nothing to do with me
