International Study Buries Cloth Masks as ‘Effectively Useless’ Once-and-For-All

A new international study, published in a peer review journal Physics of Fluids points out that the cloth masks that were forcefully placed on each citizen of the world’s face, including youngest children, were totally non-effective and useless.

The journal article was produced by British physicists with affiliations at U.K., German, and French universities and laboratories.

The scientists examined a variety of fabric masks with scanning electron microscopes, thermal imaging equipment, and sophisticated imaging software in order to perform multi-variate analyses of cloth mask performance.

“A pair of trajectories with and without inertia that start at the same point,” the journal article states. “This is for a particle of diameter 20 μm. The fabric is shown in white, and trajectories with and without inertia are traced out by purple and by orange spheres, respectively. The sphere at the collision point is shown at the true particle size, others along the path are smaller, for clarity. Note that with inertia, the particle penetrates the fabric, while without it, the particle collides at the point shown by the large orange sphere. Here, inertia carries the particle a little farther out from the side of the inter-yarn pore, avoiding a collision. Image produced with ParaView.”

The authors’ findings were recently shared by the popular British website The Daily Mail.

“Cloth masks do little to prevent the spread of COVID-19, or other airborne diseases, a new study finds,” the Mail notes. “Researchers from the University of Bristol in the United Kingdom found that 90 percent of particles could get through cloth masks, making them effectively useless during the pandemic.”

“Cloth masks have been popular in the U.S., as they are easily reusable after washing and at some points were the most accessible due to shortages and high prices for surgical or N95 masks,” the article added.
