Does n95 mask prevent haze? The difference between children and adults

At this time, it is better for adults and children to wear masks when traveling. At present, the types of masks on the market are different. So is n95 mask anti-haze? What is the difference between children and adults?
Does n95 mask prevent haze
The N95 mask can be used to prevent haze.
The filtration efficiency of the N95 mask can reach more than 95%. The particulate matter in the air can be effectively filtered, so it can be used to prevent haze.
Due to the high efficiency of filtration, the N95 mask can also be used to prevent some diseases transmitted through the respiratory tract, and can effectively filter and purify the particles of some micro-organisms inhaled, but it can not eliminate some contact infections.
The difference between children and adults with n95 mask
The biggest difference between children's masks and adult masks is the different models.
1. The size of children's masks is slightly smaller than that of adults, so as to facilitate the close fitting of children's faces and achieve the role of protection.
2. The production indicators of children's masks and adults' masks are also different. In terms of ventilation resistance, because children's respiratory system is not fully developed, when making children's masks, the ventilation resistance of children's masks is less than that of adults. Generally, it is not recommended that children wear adult masks. In addition to the model, it will also be harmful to children's respiratory system.
How to solve the pain caused by wearing N95 mask
1. You can stretch the ear band of the mask several times before wearing the mask to loosen the ear band or replace the mask with a larger model and loose ear band to reduce the pressure on the ear.
2. The pain in the ears of the N95 mask may also be caused by wearing it for a long time, or the model of the mask is not suitable. You can take off the mask or relax the ear hook, massage the painful part, promote blood circulation and relieve pain.
3. Use other soft things to pad the ear to reduce the direct contact and friction of the ear hook to the skin.
Can the N95 mask be anti-virus after washing
The N95 respirator can no longer prevent virus after washing, and the protective effect will be significantly weakened. It is not recommended to continue to use.
In daily life, if there is a need for protection, it is recommended to replace the mask in time to avoid unnecessary infection. N95 mask consists of outer hydrophobic layer and middle filter layer. Its hydrophobic layer can effectively filter the droplets in the air after waterproof treatment, and can prevent bacteria from entering and leaving the inside of the mask to a certain extent. Due to the middle filter layer, the n95 mask is usually not washable. If washing with water, the structure of the mask will be damaged, and the effect of the filter hole of the filter layer to filter the virus will be significantly reduced, so it will not play a good role in filtering the virus.
