Using the same mask again and again? This is more dangerous than not wearing mask

Central, state governments and municipal corporations are taking action against those who do not wear masks due to the Corona epidemic. Because of this, many people are avoiding fines by wearing the mask they get when they go out.

The same mask is being used frequently. Studies have shown that doing this is more dangerous than walking around without a mask.

Researchers have suggested that reusing used masks may be safer than not wearing them.

A team of researchers from the University of Massachusetts in the United States and the Baptist University in California have conducted research on whether masks are effective.

The research examined a three-layer surgical mask. This time the mask succeeds in blocking three-quarters of the smaller particles when new.

So masks that are used more than once have succeeded in blocking a quarter of the particles. This means that the masks used prevent low corona viruses.

In the study, published in the journal Physics of Fluids, the researchers say that the more often the mask is used, the worse it gets.

The flow of air around a person's face also changes after applying the mask. After applying the mask, air flows not only to the nose and mouth but also to the entire surface of the mask.

Associate Professor Dr. who participated in the study. Xinjiang said that in general, an old or new mask is much safer than wearing one without a mask. However, during the study, when the mask was used for large particles in the air, it was less than 2.5 micrometers

Ordinary people around the world are advised to use three-layer masks. Some experts recommend wearing an N95 mask. However, N95 masks are expensive. They are also not readily available to the general public.
