#CHSIAQ2022. @kprather88: Proudly accepts the title of an aerosol activist.

1) Make indoor air as clean as outdoor air.
2) How do we get to off ramps? While keeping kids safe (including from Long COVID).

#CHSIAQ2022. @kprather88: When you walk into a building you see hand sanitizer everywhere. You don't see air improvements. (same as from the EPA website).

#CHSIAQ2022. @kprather88: What did they do with Delta in San Diego public schools? Masks, MERV13, Ventilation with checks by CO2, standalone HEPA filters, small cohorts. Lunch is riskiest time (no talking). Good plan, that worked quiet well.

#CHSIAQ2022. @kprather88: This year MERV13, ventilation check, stand alone filters. Will it work?

Grass roots efforts with @CorsIAQ and @JimRosenthal4 boxes outperform HEPA filters, are cheap and address environmental justice. Schools were given money, but spent it on..

#CHSIAQ2022. @kprather88: systems that didn't perform as well. #CRboxes perform better. Air moving is a good thing. Sound = air moving. CR boxes inhale the virus at 2000 times as a human.

#CHSIAQ2022. @kprather88: If we put 1 or 2 #CRboxees in every classroom it would cost $4 per kids per year. Helps with classes with doors and windows. Improve health of kids.

#CHSIAQ2022. @kprather88: Why is this so hard? IAQ sells better than things like vaccines and masks. Highlight cognitive benefits to parents. It takes more than money, need guidance. What is the answer? Don't know. 8/8
