>you are statistically less likely to contract airbourne diseases with a mask on.
What are you basing this assessment on? Are all masks equal? Does training in mask application matter? For what duration are different types of masks effective?
- throwaway189262 6y agoGoogle is good for this. N95 and higher is effective. Mask application matters but they're effective without 100% seal. I don't think they get less effective with time, just harder to breathe through.
- ficklepickle 6y agoI find N95 easier to breathe through than surgical masks. They use static, not mechanical filtration, which doesn't seem to cause much restriction on air flow. They do get less effective with time, exposure to moisture. Using alcohol to clean an N95 will significantly reduce its effectiveness. Early on, Stanford did a study on various methods of sterilizing N95s and the change of effectiveness. Heat (70°C for 30 mins) was best. https://news.stanford.edu/2020/04/01/researchers-show-how-to-decontaminate-reuse-n95-masks/ https://news.stanford.edu/2020/04/01/researchers-show-how-to...
