Posted By TheNewsCommenter: From Theblaze.com: “Horowitz: Why masks don’t work in the real world”. Below is an excerpt from the article.

There is not a single place on earth where masks appear even to have slowed the spread of the virus, which appears hell-bent on cutting through every population until the herd immunity threshold is met. None of this should have surprised us.

How many people do you know who always wear their masks fully clamped to their faces like a respirator? Well, there are very few people who can afford to pass out after hours of oxygen deprivation. That, in a nutshell, is why mask mandates are useless against a virus, even before we examine the fact that the pores in the mask fibers are much larger than the virus itself.

Stephen Petty, one of the most experienced certified industrial hygienists and exposure experts in the country, sent me the following chart based on new research on mask filtration (Drewnick, et al.). It demonstrates that if just 3.2% of the mask space is open, the efficacy of the mask goes down to zero!

As you can see, with just 2% of the mask area open, 80% of the particles under 2.5 microns will escape. Based on that study, Petty extrapolates that masks will be 100% ineffective in blocking any particles that small when the open area reaches 3.2%.

What people forget is that aside from the size of the pores in the fabric, very few people actually wear masks the way they test them in labs or on mannequins. As Petty points out, based on a new study of filtration leakage in masks from 44 different materials, most of the seepage comes out through the sides because the molecules always travel the path of least resistance.
