What Is The Difference Between Medical Masks And Civilian Masks
1. Different sizes of protective particles
Ordinary civilian masks are mainly used to prevent haze or ordinary particles, and medical masks are mainly used to prevent small particles and particles, such as bacteria or viruses.
2. Different production standards
Medical masks need to strictly implement the corresponding industry standards, while most common masks such as those used for heat preservation and covering the face are not regulated by corresponding standards, and there is no effective guarantee for the filtering effect. Therefore, if you buy masks to block the spread of viruses through droplets, please buy medical masks that are implemented in accordance with national standards. Among them, medical surgical masks and N95 masks are preferred.
3. Different functions and classifications
Civil masks are used to filter the air entering the mouth and nose to prevent harmful gases, odors, and droplets from entering and exiting the wearer's nose and mouth. It is mainly divided into cotton masks, non-woven masks, polymer masks, activated carbon powder filter masks, and activated carbon fiber felt masks.
Medical masks can block most pathogens such as bacteria and viruses. The WHO recommends that medical workers use protective masks against particulates to prevent virus infection in the hospital air. It is mainly divided into medical protective masks, medical surgical masks, and ordinary medical masks.
Medical masks belong to a general term, which includes medical protective masks, medical surgical masks, and disposable medical masks (or medical care masks), as shown in the following table. In the context of blocking the spread of viruses through droplets, the protective effects of the three types of medical masks from high to low are: medical protective masks, medical surgical masks, and medical protective masks.
Among them, the level of medical protective masks is between KN95 and KN100 masks, and the protection level is higher, but its breathability is relatively lower than the latter two types of masks, and it is not recommended to wear it for a long time. If you wear this type of mask, you need to take off the mask and rest regularly in a safe environment and an environment with few people to avoid lung damage.
Ordinary civilian masks include cotton gauze masks, sponge masks, paper masks, etc., and their production standards are not uniform, and they are more effective in keeping warm, covering the face or preventing droplets from splashing. It does not have a very good effect in blocking the spread of virus droplets. If it is intended for protection, it is not recommended.
In summary, medical masks are more effective than ordinary masks in preventing the spread of virus droplets. It is recommended that medical surgical masks, medical protective masks and N95 masks be preferred.
