It's the only thing that makes your unnecessary mask, scientists say
Your mask works - but only if you avoid this common mistake.
Eight months in the pandemic, we all know thatmask Helps stop the propagation of coronavirus. "You protect yourself,You protect others[and] You prevent yourself from touching your face, "Joseph G. Allen, Director of the Healthy Buildings Program in Harvard, saidThe New York Times recently. However, we also know that all face coatings are not equal - and there are a number of mask errors that make them less effective to protect you from COVID-19.
With so many different styles - standard surgical masks to homemade variations at N95s - it is important to understand not only how exactly help masks helpStop the propagation of coronavirusBut also things that make your mask much less effective than it could be. So, what is the biggest problem of all?Do not pay attention to the filtration capabilities of your mask. Read more about why you need to avoid this common mask error at all costs. And for stopping coronavirus propagation, checkThis thing is better to protect you from COVID than your mask.

The purpose of your mask is to trap the airborne particles.
According to a group of scientists consulted byThe New York Times, the fibers of the material of your mask, such as cotton, "have a dense forest that particles must navigate as theyMove with the airflow. The laws of physics influence the way particles interact with the fibers and the way the mask can capture them. And for more information on the EPP protocol, checkThe CDC now says that you should wear your mask in these 7 places.
Some particles are more difficult to catch than others.
BigCovidian particles Are the easiest to trap, according to the same group of scientists, because they "slams directly in the fibers and get stuck when the airflow brings them remotely to touch". The smallest particles are captured in a slightly different way, but are also easy enough to contain. Because of their size, they are rebounded by air molecules in a random pattern, which increases "the time they spend in the forest fiber and their chances of being captured."
The average particles are however from afar the most difficult to avoid entering or getting out of the defensive barrier of your mask. The reason is that this is the case, it is because the particles of this size "follow the flow of air, twisting and turning around the fibers".

The N95 are the most effective.
The unanimous consensus among the experts is thatN95 masks Provide the most protection of all mask varieties. They are able to take 95% of the hard-to-trapping medium particles, hence their name. They also catch smaller particles and large particles than other masks.
The N95 are made of synthetic fibers that are randomly constructed and densely, which makes much more difficult for particles. In addition, these are the only masks that have an "electrostatic load that attracts and captures particles of all sizes"The New York Timesreports.

And some materials offer better filtration than others.
A study of April 2020 examined theEfficiency of filtration of different mask materials. The researchers found that, in general, the silk muslin and the flannel provide suitable filtration of small and large particles (at least 50% of the droplets were trapped by these tissues). Meanwhile, satin and synthetic silk were considered ineffective for filtration, trapping less than 30% of the particles.
The adjustment is just as important as the fibers are for efficient filtration.
While the N95 are the best, surgical masks and other fabric versions also help to brakeThe propagation of COVID. For this the case, however, the good adjustment is essential.
Your mask must meet three criteria: a large area, a tight fit around the edges and a space around your nostrils and mouth. The space around your nose and your mouth, which experts call the "breathing zone", is probably the most important factor. When you have the right breathing area, it increases the chances that the particles encounter and be trapped by a mask fiber.
