If your mask has not three, it does not really work
A new study finds that the use of this type of face covering 90% particles filters.
As the pandemic has progressed, one thing has become increasingly clear:Face masks help stop propagation coronavirus. Scientists have also been able to study theDifferent types of masks which are available to acquire a solid understanding of the best types to use to keep the public - and even the person carrying the face covering the face. Now a new study has added to proof of assembly thatYour mask does not protect you completely If it does not have at least three layers of fabric.Read on details and for more tips on masksnotuse, checkIf your face mask has one, stop it immediately.
Virginia Tech University ResearchersTested 11 different types of face masks, of which nine fabric masks made from materials such as coffee filters, a cotton t-shirt and other fabrics and a face shield and a surgical mask, Yahoo! The news. And there was a clear winner.
"We now recommend founding this study that people use a three-layer mask",Linsey Marr, PhD, a leading aerosol scientist at Virginia Tech and co-author of the study, said at a press conference on 23 November. More specifically, Marr recommends a mask in which "the two outdoor layers are a tight but flexible material that allows the mask to comply with your face" with a layer in vacuum bag or filtration material in the middle. If this is the case, your face coating could allow a filtration as high as 90%, the researchers found.
Conclusions safeguard a study published in the newspaperAdvanced ScienceIn September of Duke University. For this report, the researchers tested 14 differentCapacity of the masks to block the respiratory dropletsand they found that others only the N95, aThree-layer surgical mask Allowed the least droplets to obtain through his barrier. And come in third was a three-layer mask with polypropylene acting as a filter between two layers of cotton.

The two-layer masks consisting of some materials also make a solid job.
To determine results, scientistsused a mannequin face attached to a nebulizer simulate the expiry and the defined conversation of another face that inhaled to test different masks,including those made from bandanas, Vacuum bags, coffee filters and HVAC filters.
The researchers found that, while the three-layer materials were clearly superior, Marr added that a fabric with a "tight weaving" could also make some feasible two-layer masks.

The researchers focused on the best home options specifically.
Virginia technology scientists leading to experience quickly emphasized this, unlike Duke's researchers, they did not includeN95 masks of medical gradeThey are named such as their ability to trap at least 95% of the particles - because "for practical reasons, the fact that the general public is executed in N95, a challenge because of the shortage," said Marr a Explain.
But the most useful discovery of the experience is that even aHomemade DIY solution Can be greatly beneficial for those who choose to do their own mask. "This is not something I would ask a health care worker to wear in high-risk situations," said Marr. "They need the best protection we can get. But since it is impassable to have everyone in the general public strolling in the port of N95, I think the homemade masks are definitely useful.

They determined that the masks protect the publicand the wearer.
With the study, Marr and his team decided to determine if masks were beneficial beyond the stopping of the propagation of the virus. By testing the effectiveness of different types of masks, they also discovered which could provide another level of protection.
"Filtration works in both directions," said Marr. "If it works for source control, it will work pretty well for the reduction of exposure to protect the carrier as well", which means that any mask sufficiently effective to stop the particles to be expired in the air will be Also good enough to prevent them from being inhaled.

But the masks are not the only answer.
Nevertheless, researchers have been quick to add that masks are not the only thing that will result in the end of the pandemic. FollowingOther Public Health Guidelines can also play a huge role in everyone's safety.
"No nobody's study will tell you all the story," said Marr. "And intervention - intervention mask, social distancing, hand washing, inner ventilation - will stop the propagation of Covid-19 alone. The mask is one of the many interventions we need to combine together." And for more information on Coronavirus guidelines, checkThe CDC now warns you not to go to this place alone.
