Very Good Fitting Facemask
This is one of the better facemarks that I own.  The fit is excellent with the sewn in nose wire.  The fit doesn't feel restricting.  I use a PM2.5 filter inserted into the provided pouch.  The only recommendation I would make to the producer of this mask would be to provide two openings in which to insert an additional filter.  With only the one opening on the left side of the face mask (ref. picture), it can be challenging at times to insert a PM2.5 filter to insure you have the proper coverage.  That all being said I would still recommend this mask to a friend.
