@augieray @japierce Clean well-fitting respirators worn in clinical setting by people with training in their proper fitting and use and under regular supervision work to prevent infection. Wearing a surgical mask or loose fitting respirator that are removed and replaced regularly to eat, drink, and communicate has been shown to be entirely without merit. If the mask is not leaving marks on your face when you remove it, it is not working. If you took your mask off and put it back on it is not working. If you have facial hair your mask is not working. if you have makeup on your mask is not working. This is exactly what the Cochrane study found even among trained groups of study participants less than half managed to actually use a mask in a way that would be effective.

@antares @japierce Masks work. Taking to social media to convince people otherwise while a pandemic continues is, IMO, pretty damn unethical. https://insights.som.yale.edu/insights/no-that-new-study-doesnt-show-that-masks-are-useless

@antares Mask effectiveness is not binary. According to you, masks are either 100% effective or 0% effective and that's just not the case. Do tight, well fitting masks worn correctly offer better protection? Of course. But does having facial hair mean the mask is providing zero protection? Of course not.

Now, if you are wearing it all day below your nose, I'm with you. You are wasting your time.
