When you buy masks recently, you will find that KN95 masks/N95 masks are divided into two types: with or without breathing valve and without breathing valve. Why do masks have breathing valves? If mask wearers, people with chronic respiratory diseases, heart disease or other diseases accompanied by breathing difficulties, use KN95 masks/N95 masks, it may make it more difficult for the wearers to breathe. Why? We know that KN95 or N95 masks have a relatively high level of protection. It can be understood that this type of mask with good protection effect is thicker, so the breathing force needs to be stronger than ordinary masks. Therefore, the use of KN95 or N95 masks equipped with breathing valves can make them breathe easier and help reduce heat accumulation. The following is an online picture, this picture clearly shows the difference between the two. 1. The difference of breathing valve. We often see some more expensive masks like KN95 and N95. As for the difference between KN95 and N95, we will not discuss here. For the difference between KN95 and N95 and medical masks, you can check the 'Detailed Introduction' What is the difference between KN95 masks, N95 masks, medical masks, and medical surgical masks'. This article mainly introduces the breathing valve, such as anti-smog masks have a breathing valve switch like a button. The design of the breathing valve is one-way air out, and there are several layers of flaps on it. When inhaling, the flap will close tightly. At this time, the air inhaled by the wearer enters through the mask, that is, the air is filtered by the mask before entering the human body. At this time, the flap is closed to ensure that no particles enter. When exhaling, the mouth cover will open. At this time, the air exhaled by the wearer passes through the exhaust port to let the hot and humid air radiate. At this time, the exhausted air is not filtered through multiple parts of the copper mask
. In the figure below, the function of the breathing valve can also be clearly seen. Some people may think that the effect of breathing valve is better and the protection effect is better. The fact is, the same, whether a mask has a breathing valve or not can protect the wearer. The difference is that the N95 with an exhalation valve can protect the wearer, but because the breathing valve mentioned above is a one-way design, the gas exhaled by the wearer is not filtered, and the droplets or germs and viruses exhaled by the wearer will be transmitted through the breathing valve. To the surroundings, so the mask with breathing valve only protects the wearer but not the people around. Mainly used in industrial dust masks and anti-smog (PM2.5) masks, not suitable for medical institutions. If you are a virus carrier, please use N95 without an exhalation valve and do not spread the virus. At the same time, readers are reminded that if you see a confirmed patient wearing a mask with a breathing valve, readers should be careful! You can watch the news program, you will find that the front-line doctors and nurses wear masks without breathing valves, so In the case of medical use, there is no breathing valve, and the breathing valve is only available for civilian use. 2. Summary 1. Whether the mask has a breathing valve or not has the same protective effect on the wearer, but if there is a breathing valve, it only protects the wearer and does not protect the surrounding people; 2. If you have been diagnosed with pneumonia, please use it without it. Breathing valve mask; attached: KN95 mask wearing precautions 1. Wash your hands before wearing the mask, or avoid touching the inner side of the mask while wearing the mask to reduce the possibility of contamination of the mask. 2. When wearing a mask, it is necessary to distinguish the inside, outside, top and bottom of the mask; the KN95 mask has the printed side as the outside; one end of the metal strip/sponge strip is above the mask. 3. Do not use your hands to squeeze masks, including N95 masks, which can only isolate the virus on the surface of the mask. If you squeeze the mask with your hands, the virus will soak through the mask with droplets, and there is still a chance of infection. 4. Be sure to make the mask fit well with the face as much as possible. The simple test method is: After putting on the mask, exhale forcefully so that the air cannot leak from the edge of the mask. 5. No matter what, it’s better if you have already bought a mask than nothing. You must wear a mask when there are many people! 362
