In the absence of medical quality personal protective equipment (EPPs), many of us have turned to homemade fabric masks to help stop the propagation of coronavirus. But more and more, research has shown that all masks are not created equal, and some are ineffective squares.A new video case study produced by Australian researchers show that for a homemade fabric mask toStop viral transmissionHe must have at least two layers of fabric. Indeed, if your mask comes froma Fabric layer, you can bet that it just does not work.

Using an LED lighting system and a high-speed camera, the research team filmed theDispersion of aerosols Produced by a topic speaking, coughing and sneezing. The subject reflected the behavior of a healthy person without respiratory disease, which means that coughing and sneezes used "normal", the daily forceAsymptomatic covidant patient could produce.

When revising the sequences, the team ranked the effectiveness of the three fabric masks (as well as a three-fold surgical mask, which was judged the most effective option). Overall, the correlation between the number of fabric layers and the efficiency was STARK: the more the fabric mask had a fabric mask, the more effective it was inProtect against the propagation of droplets. The sequence revealed that the masks to a monolayer layer barely prevent the spread of the droplets: in this demonstration, the aerosols scattered through the air with a visible ease.

The team noted that the style of sewing has also had an effect on the result. Masks sewn according to standardsprovided by disease control centers (CDC) were much more effective than single fold masksMade with cotton t-shirts and hair links.

So, the next time you head outside, make sure your DIY mask is up to the task. Opt for a design comprising a minimum of two layers of fabric (ideally three!) Costué on the standards of the CDC. And for knowing if your mask keeps you safe,Watch Bill Nye Test Which masks work the best.
