Hello everyone; I think this is an ideal alternative to disposable masks. Such devices protect much better from germs, and no one except you has used them, unlike the masks we buy in stores or pharmacies. I don't want to sound unscientific, but it seems to me that this is a slightly safer option for those who don't want to get down and use their stuff. I have several of these pieces from boundbyhonor.net, and I used them constantly during the pandemic. Even now, I sometimes wear them on public transport to protect myself and my loved ones, as there are many other diseases in the world besides Covid 19
