The production requirements of medical protective masks are to prevent infection caused by airborne diameter ≤ 5μmg infectious agent or close distance (≤ 1m) contact with diseases spread by droplets. The particle filtering efficiency of the mask filter material should not be less than 95%, and the protection level is high.
Therefore, medical protective masks are also called N95 masks.
From the perspective of protection level, under normal circumstances, medical protective masks> medical surgical masks> disposable medical masks.
Can medical N95 protective masks be used repeatedly?
This is divided into two situations.
Situation 1: Users need to be in contact with patients suffering from infectious diseases for a long time. For medical staff or family members of patients who care for patients, due to close contact with patients or in the same closed space, the mask is easily contaminated. Therefore, it is required to replace every 2-4 disappears to ensure the safety of medical staff or care.
Case 2: The user is an ordinary person who does not directly touch the patient, or even if he accidentally contacts an unfamiliar patient in the external environment, he will not be in close contact and communication for a long time. , You can use the medical N95 protective mask repeatedly to avoid the loss of mask resources, but for the user’s health, even if the medical protective mask can be reused, it is recommended not to exceed 5 times.
When you need to reuse the mask, you must keep the mask removed to prevent the inside of the mask facing the nose and mouth from being contaminated. If the inside of the mask is accidentally contaminated, it must not be reused.
Of course, if the surgical protection of the medical protective mask also shows obvious damage and pollution, it cannot be reused. For your own health, please replace it immediately.
