Here is some discussion of my analysis of face mask fit and design . I've compiled it here in a blog post so that it'll be (somewhat?) easier to follow compared to a bunch of disjointed tweets  and replies.* Please read the aforementioned post so that this discussion will make more sense.  DW Rowlands:  Thanks for sharing!  I am struck by how common "ear loops too loose" is as a problem for you, too.  I really don't get why ear loops seem to be an almost-universal standard when it seems like tie-on masks fit a lot better. It does make sense that more-deeply pleated masks would fit better.  And I really should buy more masks instead of wearing the same ones multiple days in a row (though I rarely go places near other people when I'm outside). I just continue to be stressed out about spending money on things that turn out to not fit.  Rachel Taylor:  Ear loop masks are definitely easier to put on or remove, but I think the fit benefits of ...

Since the last time I posted about face masks , I've had the opportunity to try some additional designs. None of the newer designs have turned out to be great -- I'm still happiest with the design and fit of two masks I already had. But I've done some analysis and made some new insights on face mask fit and design.  I assessed the masks on the following factors: Comfort : self-explanatory, although perhaps somewhat subjective. Is the fabric comfortable against the face? Are the ear loops or ties comfortable? Fit : How well does the mask fit my face? Does it provide enough coverage over my nose and chin? How does it work with my glasses?   Measurements/size : dimensions of the front of the mask and how long the ear loops are Stability : How well does the mask stay in place while breathing and talking? I tested this by talking a bit while wearing each mask, as well as moving/scrunching my face in various ways, and yawning. Features : adjustable or not, nose wire, filter po...
