Q12. How does your crosswind air barrier reduce airborne COVID infections in our bathrooms?

Indeed bathroom operations are very susceptible to airborne infection.  Given that the CDC has officially declared SARS-CoV-2 an airborne pathogen on May 8, 2021, any interaction between a masked employee and an unmasked resident is considered high-risk to the resident. Outgassing of infectious contaminants from feces is not an issue with a crosswind unit running in a room. Nevertheless, the highest risk does occur in the bathroom, that is, spaces involving toileting and bathing, where the space is a small enclosed volume and where interaction time can be many minutes.  Therefore a resident's bathroom must have airflow directed into the bathroom from a crosswind unit during an interaction for continuous flushing of potentially contaminated air from an unknowing infected worker wearing a mask. If you have one portable unit in the room, you should temporarily position it so that its air stream points through the bathroom door covering the area of closest physical interaction with the resident, and set to the highest airflow [view here in Part 3]. If specialized bathing rooms are being used in a respiratory epidemic they also should employ the crosswind device pointed through the door if possible, set to highest airflow during use, and set back to lowest airflow when not in use.
