- denimnerd42 6y agoN95 without a charge is still going to be better than any other mask typically used. I have an N95 I've worn for the week. I can fill it up with water in the sink and it won't drip any water out. What the hell is going on there..
- pas 6y agoYeah, no questions about that. Just by having it properly fit you are probably beating 99% of mask wearers unfortunately. Though even that is magnitudes better than nothing.
