complete garbage. designed labratory experiments and modeling can suggest anything you want them to and anecdotal reviews are not empirical studies. there have been three studies now of large populations and each of them reach the same conclusion, masks are ■■■■■■■ useless. it is proven beyond doubt and has been for quite some time that masks, except n95 masks are completely ■■■■■■■ useless. they never were anything but a way of the government telling you they were doing “something” to defeat, what we’ve known again for quite some time, the undefeatable.
