1/ Risk reduction in a room that has at least 5 air changes per hour. @APSVirginia, another study shows how layered mitigations work. We need to add True HEPAS to rooms *now* to #CleanTheAir, and boost filtration, because #DeltaVariant is far more infectious.
2/ The blue line👆 is where most APS rooms are, if not WORSE for about 1/3 of our rooms. APS chose the most minimal goal it could (4 ACH). We haven’t prioritized providing the same BETTER 6ACH ventilation for all kids.
@APSVaSchoolBd, please ask for #6ACHforAll & #AirEquity!

3/ APS’ ionizers produce 20% less extra clean air, so they’ve underestimated ventilation.
They’ve doubled capacity, which means now 1/2 the clean air for each student returning to school in a week, against #DeltaVariant, which is 2x more infectious.
