I have tried numerous masks and I prefer to wear the ones with pockets for changeable PM 2.5 five-layer carbon filters which can increase the layers of protection on the mask from 2 or 3 to 6 or 7 (depending on the mask and filter). Of the multiple ones I have tried, those in the link below have worked best for me as they are easy to adjust and feel the most comfortable to me. My face is pretty round and these work really well for me as they have a good fit and do not restrict breathing too much. They also seem to feel just as durable after numerous washes.
