Cluster-Randomized Trial of Air Filtration and Ventilation to Reduce Covid19 Spread in Homes

Investigators are using box fans with attached MERV16 filters, a design that has been tested and published in the scientific literature.

The pamphlet has information on how the filtration fans work through visual images; and images of ventilation improvements in the home through opening windows.

On day 3-4 of the study, the study coordinator assigned to the house will call and check in regarding the filtration fan usage and remind families about the importance of filtration and ventilation.
