Can anti-smog masks block cigarettes?

Due to the emission of industrial waste gas and the increase in the number of cars, the amount of exhaust gas emissions has also increased, so air pollution is now very serious, especially in some more developed areas, so smog often occurs During the weather, many people wear anti-smog masks when going out. Can anti-smog masks block cigarettes? Can anti-smog masks block smoke?

1. What is an anti-smog mask?

The so-called PM2.5 refers to small particles in the air with a diameter less than or equal to 2.5um (microns). What people call PM2.5 masks (the PM2.5 masks referred to here is a name) are anti-haze masks. The anti-haze masks currently on the market are mainly made for the fine particles of PM2.5. Yes, this anti-haze mask can effectively filter PM2.5 fine particles, and the airtightness of the anti-haze mask also determines its ability to filter and separate suspended particles.

2. What can it prevent

Anti-smog masks are mainly respiratory protection against certain oily particles, such as dust, pollen, various production dusts and non-volatile fog. Such as air pollution (PM2.5um (micron) fine particles), it can effectively prevent such fine particles in the air from entering the human alveoli, reducing the risk of asthma, bronchitis, and cardiovascular diseases. In this case, can anti-smog masks block cigarettes?

3. Can it block cigarettes?

Because cigarette smoke also belongs to the category of PM2.5, and the concentration of indoor cigarettes is so high, anti-smog masks can only be used under certain conditions. The extent to which it prevents the inhalation of cigarettes, and the sealing performance of this anti-smog mask also determines the extent to which it prevents the inhalation of cigarettes. Therefore, choosing a good anti-smog mask can prevent the inhalation of cigarettes and reduce the occurrence of respiratory diseases.

4. Why can the hood block cigarettes

All the smoke from burning cigarettes is some tiny particulate matter. In terms of the size of the particles, it belongs to the category of PM2.5, which is One of the main sources of harm to the respiratory system when entering the human body. The tiny particles of this smoke have a very small diameter and can stay in the air for a long time, especially in a closed and unventilated room. Second-hand smoke has become the main source of indoor PM2.5.

5. The concentration of PM2.5 in indoor smoke

We know that anti-smog masks can block cigarettes, so let us take a look at the concentration of PM2.5 in indoor cigarette smoke. When a person smokes in a room of 35 square meters, the concentration of PM2.5 in the air can reach 300 micrograms/cubic meter after smoking one cigarette. According to the Chinese government's standards for PM2.5, PM2.5 of less than 75 micrograms per cubic meter is considered a safe value. This experimental result is four times the safe value. If you open windows for ventilation, it usually takes more than 15 minutes to effectively remove the hazards of indoor smoke.

6. Warm reminder

For the health of yourself and others, please do not smoke. Smoking is also one of the sources of PM2.5 dust.
