SCHOOLS: I'm presenting today for a State DPH on steps schools can take on ventilation. Re-sharing some things I hope people find helpful (all available since summer 2020)
Simple #HealthyBuilding strategies: more ventilation, better filtration, portable air cleaners, VERIFY

But, as I've been saying since March 2020, you can't just say 'more outdoor air' without giving a specific target. My recs is 4-6 ACH.
How can I determine if my classroom is meeting these targets? We have a simple 5-step guide for how to do this.
If you're using CO2 to determine ventilation, the 'how to' is covered in the 5-step guide. You can also use our cool little tool to help set a target CO2 level based on your ACH target. (works for offices and any other place, too! link to tool: forhealth.org/tools/co2-calc…
If you're using portable air cleaners, but not sure how to size them for the room, we have a tool for that, too. (rule of thumb: look for CADR of 300 for every 500 square feet)
The multiple benefits beyond covid and infectious disease are well-documented for every age group, and go well-beyond air quality (blow up the pic and read that table (!)
