What types of masks are better? .. Here is the answer

With the great spread of the new Corona virus, with its new types, it has become necessary to be more cautious and cautious than in recent months, and to use masks useful for this purpose, especially after that scientists agreed that transmission of the disease through the air after the patient’s spray is most likely.

With the many types, confusion hangs over the atmosphere as to which type is more useful, however, Linsy Mar, a professor at Virginia Tech specializing in communicable diseases, revealed to the French News Agency that the effectiveness The mask depends on two basic things, namely, its ability to filter and its ability to control and tighten it.

They are the best

The specialist pointed out that good filtration prevents the passage of as many particles as possible, and that a tight fit of the muzzle means there is no leakage around its edges where air can pass, and therefore the virus.

She pointed out that even a small opening can reduce the effectiveness of the mask by 50%.

Surgical muzzle

The best material that prevents the entry of fine particles is non-woven polypropylene used in many surgical masks or masks equipped with a filter such as “KN 95”. The best type of fabric is well-wrapped cotton.

Multiple layers

She added, “You should feel your mask pulling inward during the inhale, and if you put your hands on its sides, you shouldn’t feel the air coming out during the exhale.

It is also known that masks with a metal shank fit better at the nose and are more effective in this regard when the rubber bands are wrapped around the head and not just around the ears. Marr explained that if you are wearing a rag mask, then choose one that contains multiple layers, with a small pocket allowing the insertion of the filter. Or, you can place a surgical mask under this cloth.

The muzzle N 95

Surgical masks are made of a material that has a great ability to filter, but it tends to be loose, so adding a fabric mask can help keep its edges attached to the face, reducing the possibility particle leakage.

In addition, adding a layer improves the filtration process. If one coat can retain 50% of the particles, then with two coats this percentage increases to 75%.

Pay attention!

However, the specialist recommended special attention, as she does not recommend wearing more than two masks, as this can affect the ability to breathe well, confirming that there is another option, which is the “KN 95” muzzle or “FFP2”. Depending on the country, it is often reserved for medical personnel. These masks are the most capable of filtering the air.

It should be noted that recent studies still indicate the possibility that masks will accompany us even after the end of the Corona virus crisis, but only partially.
