Rebecca Watson recently released a video detailing the study behind the news reports claiming that neck gaiters are worse than not wearing a mask.  Basically, the study wasn’t about the effectiveness of various kinds of mask, but about a possible method to test the effectiveness of masks:

As this article from ScienceNews points out, the type of material, thickness, and the environment are the most important factors to the effectiveness of any face covering.  Droplets don’t tell the whole story, and hopefully, more studies will be conducted to determine which face coverings, aside from N95 masks, are the most effective.

I think I’ll stick with the cloth and coffee filter masks my wife makes for personal use.
