This is some recent info I found about better masks. I'm back using a mask in public indoor spaces for the winter. I had covid in November, then flu in December. This brand is highly rated, I've seen it in articles including the NY Times Wirecutter. They are USA made, easy breathable masks with very comfortable earloops. At least the holiday weeks, with travel and parties, are behind us now.

They make the high quality N95 masks (NIOSH approved). But they also make this "same" mask with ear loops, cushion over the nose clip and a foldable mask, so they call it their D95 mask. It comes in many colors. Order: Order Demetech D95 mask with ear loops
