A new study examines the efficacy of particle filtration by woven fabric, which consists of fibers twisted together into yarns. There are, therefore, two lengthscales: the diameters of the fiber and ...

New research shows that while many cloth and medical masks fall short against tiny airborne particles, simple hacks like overmasking or using braces can dramatically improve your protection, yet only ...

Every day, N95, KN95, KF94, and surgical face masks protect millions of people from smoke, dust, and other particulates, as well as germs that can cause serious illness. These masks act like a bouncer ...

In a recent article published in the journal Physics of Fluids, researchers explored the influence of perimeter leakage on the effectiveness of face masks. Study: Perimeter leakage of face masks and ...

As multiple wildfires burn across Canada and the western U.S., millions are being exposed to the dangers of smoke inhalation.

After consulting with medical doctors, we rounded up the best N95 masks for travel, wildfire smoke, poor air quality, and ...

In a new study, researchers used principal component analysis along with fluid dynamics simulation models to show the crucial importance of proper fit for all types of masks and how face shape ...

New research from the University of Surrey and the University of Bristol has shown that FFP2 (filtering facepiece) respirator masks are five times more efficient at filtering particles that carry the ...

WASHINGTON, March 1, 2022 -- Like many other viruses, COVID-19 is transmitted primarily via particles carried in the air. An infected person breathes out particles containing the virus into the air, ...

WASHINGTON, May 3 2022 – In its updated guidance at the start of 2022, the U.S. Centers for Disease Control and Prevention said loosely woven cloth masks offer the least protection against COVID-19, ...
