Over on Your Local Epidemiologist, Katelyn Jetelina has a post about improving indoor air: “The power of ventilation and filtration.” I recommend reading the entire post, but, because it should be of importance to the special education community, I especially want to underscore this segment:

Individuals should advocate that their schools and workplaces improve ventilation. And, most importantly, that it’s done right. Unfortunately an investigation found that more than 2,000 schools across 44 states installed unproven devices during the pandemic that even had the potential of being a pollution source themselves. Here is a great 5 step guide to checking ventilation rates in classrooms.

There is a shipload of sensible analyses and recommendations in Jetelina’s posts.
