Well, @lioness, I'm with Humana, too, but no masks yet in the mail. I know each plan is different and I'm glad your plan has sent you some "freebies"! I finally ordered two masks and pkg of filters from Etsy. I still have some hospital masks from an earlier purchase and wear a scarf on walks and in the front yard...just in case. Looking forward to trying on the new ones and hope they will be comfortable and easy to breathe through.
