He explains that while the valves make it easier to “breathe out and get rid of heat and moisture”, they also pollute the surrounding air with unfiltered aerosols.

However, according to the CDC, yes one exception to the rule: “An N95 respirator with an exhalation valve provides the same level of protection for a wearer as a valve-free respirator,” notes the organization’s website. This is only Valve respirators are considered safe enough to maintain a sterile field and prevent virus transmission.
