Wearing a mask has a certain effect. Generally, dust masks cannot completely block the chemical components in second-hand smoke, but they can still block those chemically harmful substances, which can minimize harm to the body. Therefore, wearing a mask to prevent second-hand smoke is a must. Effect. Wearing a mask can prevent secondhand smoke, just like sieve filters out impurities, as long as the pollutant particles in the air are larger than the sieve holes on the mask, impurities can be filtered out. It is best to choose n95 masks.

Medical protective masks have a certain role in preventing second-hand smoke, but ordinary masks cannot prevent second-hand smoke.

Ordinary disposable medical masks do not have the effect of preventing second-hand smoke. The filtering efficiency of ordinary disposable medical masks is not high enough, and the filtering effect of medical protective masks will be higher, so it can prevent second-hand smoke. The main blocking object of masks is particulate matter, and smoking cannot be completely blocked by wearing masks.

The original way of wearing a mask to protect against second-hand smoke is the same as that of a sieve to filter impurities. As long as the pollutant particles in the air are larger than the sieve holes of the mask, the pollutants can be filtered out. Therefore, it is very important to wear a mask to prevent second-hand smoke and what kind of mask to choose.

KENJOY FFP2 face masks protect against secondhand smoke.

FFP2 Face masks use high-efficiency electrostatic filter cotton technology, and the activated carbon in it can well filter the oily particles in second-hand smoke. In addition, the general series of protective masks such as n95 and n99 cannot filter second-hand smoke.

The appearance of FFP2 face masks is mainly dark gray, in which high-efficiency electrostatic filter cotton technology is used, which greatly improves the filtration rate. The activated carbon component in FFP2 face masks can absorb a lot of odors and keep the air inside the masks fresh, so it is very suitable to wear FFP2 face masks to prevent inhalation of second-hand smoke.

Wearing a mask has a certain effect. Generally, dust masks cannot completely block the chemical components in second-hand smoke, but they can still block some chemically harmful substances, which can reduce the harm to the body to a certain extent. Dust masks have only a certain effect. Masks of KN95 and KN90 standards and above have small gaps and can contain most of the particulate matter, which can prevent second-hand smoke to the greatest extent. In addition, common filter masks on the market in my country, such as ordinary medical masks, cotton masks, gauze masks, etc., are used in this way, but due to the large gap between the fabrics, they are not very effective in preventing second-hand smoke.
