Can I use a respirator with an exhalation valve?
Usually, yes. An exhalation valve reduces excessive dampness and warmth in the mask from exhaled breath.
The valve opens to release exhaled breath and closes during inhalation so that inhaled air comes through the filter. Health care workers may wear respirators with exhalation valves unless the patient has a medical condition (such as an open wound) for which a health care worker would normally wear a surgical mask to protect the patient. Similarly, respirators with exhalation valves should not be placed on a patient to contain droplets and prevent spread of infectious particles; surgical masks are adequate for this purpose.
