Disappointed
I had high expectations for this mask: complete coverage, pocket for pm2.5 filter, neck strap, e.g..<br /><br />However:<br />* There is no "stiffener" over the nose (big open gaps around my nose)<br />* There is no "stretch" in the ear/neck strap (tightening one spot loosens another)<br />* It's just difficult to put on, adjust, etc.<br /><br />The included card says, "Not Medical Grade -- not a substitute for following the applicable CDC guidelines."  I suggest you look elsewhere, this is probably not your best choice.  I won't be wearing mine unless all my others are in the wash (not likely to happen).
