Summary

This study will test if affordable air cleaning devices (box fans with a filter attached and/or ultraviolet light lamps) installed in classrooms can reduce the number of viral respiratory illnesses schoolchildren experience.

Conditions

  • SARS-CoV2 Infection
  • Influenza Viral Infections
  • Respiratory Viral Infection

Interventions

DEVICE

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.

DEVICE

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).

DEVICE

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.
