Hi Mastodon & @violetblue!
I'm looking for an N95 mask with no metal but with an exhale valve for my spouse to wear at his warehouse job. He's been wearing 3M 8210V religiously since 2020 to keep from bringing Covid home to me, but his employer is reinstating the use of metal detectors and if the metal staples used to attach the straps set it off, I'm pretty sure he's going to punch out anyone trying to remove his mask.
Suggestions? Boosts appreciated!
