@windwalker @macjane The N95 mask with an exhalation valve in the front will protect the wearer, but it doesn't protect others. In fact, if the wearer is infected, the front valve will concentrate the infected air and shoot it toward any person in front of the wearer. To guard against unknowingly infecting others, a second, cloth or lobby-type disposable mask should be worn over the N95 one to cover the valve.

Windwalker. Terri. I am concerned about masks as I will be keeping an in office apt with the orthopedist next week for an evaluation and X-ray of my shoulder, which has been excruciatingly painful since the beginning of July. The office requires that I sign in before the appt which means that I will have to go thru’ the waiting room where there will be several patients waiting to be seen by various specialists. I am not able to breathe well in an n95 mask and almost passed out in the super market back in March before the pandemic became so widespread. My heart also begins to race. Would you recommend that I wear a cloth mask and a face shield and gloves. Do you think that would be protection enough?? I do need to get some relief as my sleep has been badly affected by the pain in my shoulder. Thanks for your input.
