Is activated carbon harmful to the human body?

Now, not only is the air pollution index gradually increasing, but even the indoor spaces we live in are not necessarily safe. Especially in newly renovated houses, the formaldehyde and benzene content of various decoration materials are very high. If some measures are not taken, these harmful substances will be absorbed by our human body. Therefore, activated carbon has become the first choice for the general public. So is activated carbon harmful to the human body?

Activated carbon is a physical adsorption, very safe, non-toxic and harmless to the human body!

Activated carbon is a type of microcrystalline carbon material made of carbon-containing materials, which has a black appearance, a developed internal pore structure, a large specific surface area, and strong adsorption capacity. Because activated carbon contains a large number of micropores that are invisible to the naked eye - the internal surface area of ​​the micropores in an activated carbon particle the size of a rice grain is equivalent to the size of a large living room wall, and the large number of surface molecules of activated carbon can generate strong gravitational force to adsorb impurities and heavier molecules in the medium, such as chlorine, benzene, ammonia, etc. Therefore, placing a certain amount of activated carbon at home can effectively "capture" various harmful and toxic gases and impurities. First look at the density. The more pores in the activated carbon, the higher its adsorption performance. It is recommended to purchase activated carbon products with low density, light feel, and large weight and volume.

However, just like the chessboard of pinball checkers, the adsorption effect of activated carbon on harmful gases is equivalent to embedding individual chess pieces into the spaces on the chessboard. The adsorption capacity of activated carbon will gradually weaken as the micropores are filled, and eventually reach adsorption saturation. Therefore, if you use activated carbon to purify the air in a place where there are constantly new pollution sources, you need to replace the activated carbon after a period of time.

Through the above introduction, friends have already known that activated carbon itself is not harmful to our human body. The principle of using activated carbon to purify indoor air quality is adsorption. Various harmful substances will be adsorbed by activated carbon. Therefore, the greater the density of activated carbon, the higher its adsorption capacity. Friends can refer to this when purchasing.
