Everyone’s lifestyle changed after COVID’s entry. Mask has become a must in people’s lives. A mask is now just as important as sandals for feet when stepping out of the house. If somebody ever goes out without a mask, locals look strange as if he has committed a crime. This has greatly increased the demand for masks. However, many types of masks have entered the market. Some are worn for a few hours while others last for a day or more.
Also, cloth masks are worn by those who wash them regularly. N95 masks are specialized for protection against corona. However, they are more expensive. Otherwise, they are discarded for a certain period of time due to a lack of opportunity to clean them. But, American scientists have checked this problem. N95 masks also have a new approach that allows them to be worn more often.
Scientists at Beth Israel Decones Medical Center in the United States have developed a vaporized hydrogen peroxide solution for the N95 mask. With this, a mask can be purified. With help of this, it is said that purified N95 masks can be used ten times. It is said that the strength and effectiveness of a mask do not diminish even if they are used over and over again.
