It turns out that repeated use is much more dangerous than none at all..

This is evidenced by a study conducted by experts from the United States, writes the Daily Mail.

Researchers analyzed the effectiveness of three-layer surgical masks using computer imaging. They found: masks in a new state can filter up to 65% of aerosol particles, with repeated use - only 25%.

PPE used cannot filter out particles smaller than 2.5 micrometers.

In addition, repeated wearing of a medical mask will significantly reduce the airflow rate in the face area.. With a combination of factors, the effectiveness of a mask to protect against COVID-19 is significantly reduced.

Experts emphasize: repeated use of a medical mask leads to its deformation, and, as a result, loss of protective function. As a result, a person develops a false sense of security..
