in general would encourage wearing a mask that stops PM 5 and above in busy urban settings, It protects the wearer from urban pollution

A PM10 mask is sufficient against most viruses and microbes but your body gets less oxygen or you need to breath deeper/stronger not an ideal solution

Further masks must be changed every few hours or they inflict more damage due to accumulation of debris and microbial expanding population on the mask
