@merpreb, Morning Merry - Nope, I wear one mask but it has 4 layers and a pocket for a PM 2.5 carbon filter similar to this one but I can't remember if this is where I got mine - https://www.reusablefc.com/collections/all/products/reusable-face-cover.

My neighbor who worked in healthcare on cardiology equipment as a tech moved in the fall and he was still having supplies autoshipped to his old address. The new people gave me a package for him and I saw that it was from a medical supply company and texted him to send me his new address but he said it's just some N95 masks so you can keep it. I gave some to my son-in-law but kept the rest as back up but unfortunate for me, I hate the bands over the head worse than the ear loops...and these have the over the head bands.
