Converted to a N95 mask protection.
This mask is designed for a 3-5 layer charcoal slip in filter, which i believe does little to protect you from the COVID 19 virus.  I understand that a N95 mask offers the best protection for you , but are hard to find.  I had a couple of unused  3M-N95 paper masks left over from a clean up job.  They did not have the built in valve.  I simply removed the two straps from the M95 and inserted the whole N95 (w/adjustable nose bridge wire) in this mask. I now have an attractive adjustable fit mask with an lanyard, and best of all the protection of a N95 mask filter, rather than the less effective thin charcoal filter that in effect protects other people rather than you.  BINGO..........
