Note: Masks that have an exhalation valve are designed for the comfort of the wearer. Exhalation valves help reduce breathing resistance when the wearer exhales (breathes out). These are one-way valves that open only when the wearer exhales. Properly fitted face masks that have an exhalation valve protects the wearer from particles entering the wearer’s breathing zone, but does not protect people, other than the wearer, who are not wearing any type of face mask.
