Can an anti-fog mask block cigarettes?

Due to the emission of industrial waste gas, the increase of cars and the increase of tail gas emissions, air pollution is very serious now, especially in some developed areas, so smog weather often occurs, and many people wear anti-fog masks when they go out. Can an anti-fog mask block cigarettes? Can an anti-fog mask stop smoke?

1. What is an anti-fog mask?

The so-called PM2.5 refers to fine particles with a diameter less than or equal to 2.5um (micron) in the air. PM2.5 mask (here refers to a name) is an anti-fog mask. The anti-fog masks appearing on the market now are mainly made for the fine particles of PM2.5, which can effectively filter the fine particles of PM2.5, and the tightness of the anti-fog masks also determines its ability to separate suspended particles.

2. What can be prevented?

Anti-fog mask is mainly used to prevent the breathing protection of some oily particles, such as dust, pollen, various productive dusts and non-volatile fog and other air pollution (fine particles of PM2.5um (micron)), which can effectively prevent such fine particles from entering human alveoli in the air and reduce the induction rate of asthma, bronchitis and cardiovascular diseases. In this case, can an anti-fog mask block cigarettes?

3. Can you quit smoking?

It is precisely because the smoke of cigarettes also belongs to the category of PM2.5 that the concentration of indoor cigarettes is so high, so the anti-fog mask can only prevent the inhalation of cigarettes to a certain extent, and the tightness of this anti-fog mask also determines the degree of preventing the inhalation of cigarettes. Therefore, choosing a good anti-fog mask can prevent cigarette inhalation and reduce the occurrence of respiratory diseases.

4. Why can a range hood block smoke?

All the smoke produced by cigarette burning is some tiny particulate matter. In terms of particle size, it belongs to the category of PM2.5 and is one of the main sources of harm to the respiratory system. The tiny particles of this smoke are very small in diameter and can stay in the air for a long time, especially in a closed and unventilated room. Secondhand smoke has become the main source of indoor PM2.5.

5. the concentration of PM2.5 in indoor smoke.

We know that anti-fog masks can block cigarettes, so let's take a look at the PM2.5 concentration of indoor cigarette smoke. When a person smokes in a room of 35 square meters and smokes a cigarette, the concentration of PM2.5 in the air can reach 300 μ g/m3. According to the China government's standard for PM2.5, it is safe for PM2.5 to be lower than 75 micrograms per cubic meter, and the experimental result is four times the safe value. If windows are opened for ventilation, it usually takes more than 15 minutes to effectively remove the hazards of indoor smoke.

6, warm tips

For the health of yourself and others, please don't smoke. Smoking is also one of the sources of PM2.5 dust.
