Do N95 and KN95 masks with breathing valves have any effect on anti-virus? _ Protection | Quote Reply | | Original title: Are N95 and KN95 masks with breathing valves effective in preventing viruses? N95/KN95 respirator is divided into respirator with breathing valve and respirator without breathing valve. As long as it is a qualified product, the protective effect of a mask with the same level of protection is the same whether it is equipped with a breathing valve or not. The difference between them lies in the resistance of breathing and the comfort of wearing. People who suffer from chronic respiratory diseases, heart diseases or other diseases accompanied by dyspnea symptoms, the elderly, pregnant women and other groups should be cautious in using N95 mask. If you must use it, choose a N95 mask with an exhalation valve, which can greatly reduce the respiratory resistance, reduce the respiratory pressure of the user and make it more comfortable to wear. If you wear a mask without a breather valve, there may be water droplets in the mask for a long time,free shipping disposable coverall, which will accumulate heat when breathing, increase breathing resistance and cause discomfort. In this case, you can try to buy a N95 mask with a breather valve, because as long as it is a qualified product,CE Certificate KN95 Mask, it will not affect the respiratory protection of the wearer. It's just a N95 mask with a breather valve, and it doesn't protect the people around it. Of course, whether to buy a mask with a breathing valve or not depends on two situations: If you are a healthy person, whether you buy a N95 mask with or without a breathing valve, the only difference is that when you wear it, you feel comfortable and wear a N95 mask with a breathing valve, which can also keep the virus out of the mask. If you are a virus carrier, KN95 Mask for Epidemic Prevention and Control ,Full Body Disposable Coverall, for the sake of the health of the people around you, you should choose a N95 mask without a breathing valve, because the N95 mask with a breathing valve, when the virus carrier breathes, the exhaled gas will not be filtered by the mask, but directly discharged into the air, which may exhale bacteria or viruses into the surrounding air and infect the people around you. In addition, not all masks labeled N95 can protect against germs. There are two kinds of N95 mask, one is anti-biological mask, that is, N95 medical protective mask, and the other is dust mask. They have the same protection level and have passed the N95 level test, but the implementation standards are different and the objects of protection are also different. The standard for biological masks is GB19083-2010 Technical Requirements for Medical Protective Masks, which is used in the medical and health industry, such as epidemic prevention stations, hospitals, CDC, etc. The standard of dust mask is GB2626-2006 Respiratory Protective Equipment Self-priming Filter Particulate Respirator, which is used in industries such as coal mining, petroleum processing, mining and other industrial and mining enterprises. For the novel coronavirus, N95 medical protective masks should be selected for biological protection. To sum up, the masks that can effectively prevent respiratory infectious diseases are medical protective masks and surgical mask. These two kinds of masks belong to medical equipment. If conditions permit, it is best to buy these two types of masks. How to distinguish these two kinds of masks? The following process can be followed: Look at the registration number of medical devices-confirm that it is a medical device,KN95 Mask with Fast Shipping, look at the implementation standard-implement GB19083-2010 "Technical Requirements for Medical Protective Masks" is N95 medical protective masks-implement YY 0469-2011 "Technical Requirements for surgical mask" is surgical mask.
