Their behaviour is therefore highly variable depending on volatile organic compounds and ambient conditions (temperature and humidity). In general, however, the pore size of activated carbons is not regular, so they are called "unstructured" porous materials. Activated carbons with different pore diameters will have different gas efficiencies. To purify the air of polluting gases, activated carbons with pores measuring 1 to 2 nanometres are the most suitable. Woods can have pores larger than 50 nanometres. Coconut shells thus give micro-pores ( < 2 nm). The pore diameter depends on the method of activation and the pores present in the raw material used. Therefore, the effectiveness of an activated carbon on gases can depend on the ambient humidity. The coal then retains the molecules of gases and liquids. Once activated (physically or chemically), the surface area of the activated carbon can reach 400 to 2,000 m².g-1. It can be produced from any carbon-rich plant organic matter: wood, bark, coconut shells, etc. Our purifier also includes a handy night light feature with adjustable brightness options, as well as a child lock function for baby nurseries and kids’ rooms.Activated carbon is a material consisting essentially of carbonaceous material with a porous structure.
