When should I change my disposable face mask?
Detmold Medical has not conducted studies about how long you should wear a Detmold Face Mask before it loses effectiveness.
In the context of COVID-19, the Australian Government Infection Control Expert Group recommends, “A surgical mask can be used continuously for up to four hours, as long as it does not become moist, soiled, or damaged. Surgical masks must not be stored or reused after removal.”
