And the masks are probably made in China.
But how are N95 masks different from KN95 masks? The main difference lies in how the masks are certified. ?In general,? says Sean Kelly, founder of New Jersey-based PPE of America, ?N95 is the U.S. standard, and the KN95 is the China standard.? Because of this, only N95 masks are approved for health-care use in the United States, even though KN95 masks have many of the same protective properties.
Scientists Find Putting Pantyhose on Your Head Makes Your Mask SaferAfter testing seven ways to make masks seal better around the face, researchers found that a pair of hosiery does the trick best.by Samantha ColeFebruary 3, 2022, 11:24amI recently came across a selfie from April 2020 where I wore a ?mask? that was just a bandana folded up and secured with hair ties to make a sad, limp origami face covering. It?s hard to believe this was the viral (lol) personal protective gear trick at the time, wrapping a linty old piece of cotton around my face to go buy and then wipe down my groceries. But back then, not even nurses could get their hands on a mask; these were just the ad hoc hacks we made up to stumble through a terrifying, confusing time. In 2020, researchers from the University of Cambridge started testing out some of the ways people might adjust face masks to make them fit better on their faces. Their findings were finally released as a peer-reviewed study this week in the journal PLoS ONE. A better seal around the edges of the masks means more protection from COVID-19, but most consumer-level surgical masks and KN95s leave gaps around the sides. The researchers tested seven different hacks that attempt to close the gaps, on surgical and KN95 masks: Taping the edges of a mask to one?s face Filling the sides of a mask with gauze Binding the mask to the face with gauze (the ?mummy? method) Putting a knot in the ear loops Rubber bands around the front to create a ?brace? against the mouth A slice of pantyhose wrapped around the faceCONTINUEDYOU MUST FINISH ARTICLE AT LINK ABOVE You will be displeased if you miss it, trust me.
