Interventions
Box Fan
Classrooms assigned to this arm will be equipped with 2 - 8 box fans each with a single minimum efficiency reporting value-14 (MERV-14) filter sufficient to increase effective air changes per hour to 12 based on the clean air delivery rate measured in cubic feet per minute of the box fan + filter \* 60 divided by the room volume.
UV Germicidal Irradiation Lamp Unit
Classrooms assigned to this arm will be equipped with one or two 222nm wavelength light ultraviolet germicidal irradiation lamp units (number of units per classroom based on room volume).
Combined: Box Fan and UV Germicidal Irradiation Lamp Units
Classrooms assigned to this arm will be equipped with both box fans and UV germicidal irradiation lamp units.
