The introduction of breathing valve

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 the mask wearer, who suffers from chronic respiratory disease, heart disease or other diseases with symptoms of breathing difficulties, using KN95 mask/N95 mask may make it more difficult for the wearer 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 help them breathe more easily and help reduce heat accumulation.


This article mainly introduces 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 mouth cover will close tightly. At this time, the air inhaled by the wearer enters through the mask, that is, the air is filtered through the mask before entering the human body. At this time, the mouth cover 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, allowing the hot and humid air to escape. At this time, the exhausted air is not filtered by the mask.

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 pass through the breathing valve. 


To the surroundings, 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.
