The goal of this page is to continually document best practices for running pandemic-safe community fit testing clinics.

Indoor fit testing

Some methods of fit testing, e.g. TSI Portacount quantitative testing, must be done indoors. This is because enough ambient aerosols must be present in the indoor environment. This constraint also may limit the usage of e.g. HEPA filtration indoors while fit testing is in progress (?)

Outdoor fit testing

Qualitative fit testing can be done outdoors or indoor.
