I love these – do they block viruses?
"Hi – I’m gonna order more of these. But, I just realized that I don’t know if they block viruses. I assumed they were KN 95 level of protection against viruses. Regarding how long they last for me, I am lucky in that I can brush my teeth right before I put it on and I don’t have to wear them for very long at a time. I’ve gotten at least 15 uses out of every mask. They look way better than the other kind of masks I have seen. Thank you so much for any input on this and thank you for making such a comfortable mask. I will give it five stars if it is proven to black viruses. Maria L Fort Collins, Colorado"
