https://lutema.com/blogs/news/what-is-an-m95-and-how-does-it-compare-to-n95-or-kn95 I happened upon this looking for USA made quality face masks with ear loops for a relative who had trouble with the N95 double bands after shoulder surgery. Company sells different sizes for different head sizes, even kids, and different colors. They also have sizing charts with each type mask they sell. So far, so good, with purchase. From San Diego, USPS standard shipping for them arrived here in No. VA in 5 days.
