However, we cannot forget the importance that the World Health Organization has played in this context. It initially made different recommendations for the groups including healthcare personnel, people in direct contact with the infected and people with symptoms (Holland et al., 2020, Jansson et al., 2020) on the one hand, and for the rest of the people on the other. Therefore, on 20 April 2020, face mask it still recommends that “If you are healthy, you only need to wear a mask if you are taking care of a person with COVID-19” .

While this type of mask tends to gap and leak at the sides, any mask is better than no mask at all.
Subsequently, FFP respirators were subjected to a fit test to verify that they fit properly and that the filter material continued to be a good barrier against particles. The fit test results for an untreated FFP respirator showed an average value of 162. Therefore, a reprocessed FFP respirator must have a minimum average value of 100 to pass the fit test. Based on these, it was preliminarily concluded that “double sterilization using a short process with hydrogen peroxide gives an acceptable result” . We must remember that either PPE (-FFP respirators) or medical face masks manufactured according to technical standards, require that they be discarded after use, since they are heat sensitive and are not designed to undergo a process as severe as sterilization . This is why manufacturers like 3M initially advised against the sterilization process .
Face masks combined with other preventive measures, such as getting vaccinated, frequent hand-washing and physical distancing, can help slow the spread of the virus that causes COVID-19. Three-ply filtration and nonwoven fabric prevent exposure to most harmful particles for comfort in dirty environments. These instructions may show how to make sure the product fits properly.

However, researchers are testing ways to disinfect and reuse them. Some masks and respirators offer higher levels of protection than others, and some may be harder to tolerate or wear consistently than others. It is most important to wear a well-fitting maskor respirator correctly that is comfortable for you and that provides good protection. MacIntyre C.R., Seale H., COVID 19 Test Kits Dung T.C., Hien N.T., Nga P.T., Chughtai A.A. A cluster randomised trial of cloth masks compared with medical masks in healthcare workers. Logically, other regulations also establish their particular level of effectiveness. Table 2below summarizes the FFP respirators that are recommended as PPE against COVID-19, according to the standards of different countries .
Parents and caregivers may have questions about NIOSH-approved respirators for children. Although respirators may be available in smaller sizes, they are typically designed to be used by adults in workplaces, and therefore have not been tested for broad use in children. They filter at least 95% of particles in the air when approved by NIOSH and when you have a proper Medical masks fit. Lists of masks that meet these standards and more information on their availability can be found on the NIOSH Personal Protective Equipment Information (PPE-Info) webpage. These masks have markings printed on the product to indicate they are authentic. CDC’s mask recommendationsprovide information that people can use to improve how well their masks protect them.
“This means the mask can filter out at least 95 percent of particles of all sizes, and at least 98 percent for Levels 2 and 3,” she said.
