I was under the impression that the event mentioned was voluntary attendance. Be that as it may, what kind of mask do you suggest??. The much talked about "N95" mask is to prevent the inhalation of airborne particles (IE dust) and do NOT filter out viruses from being breathed in or anything anything breathed OUT, surgical masks are made to filter exhaled air but not inhaled and cloth filters little smaller than a mosquito. So, if you are trying to prevent the spread of a virus, either from you to others or from others to you, which one would you choose??.
