Activated charcoal is very ineffective after repeated use, activated carbon purification principle is adsorption, but its capacity is limited, consumers should be based on the size of the space, the concentration of pollutants, such as a reasonable allocation of the number of activated charcoal, the need to be replaced in a timely manner within 7-15 days.

Activated carbon is a hydrophobic adsorbent made from carbonaceous materials, such as coal, wood, fruit shells, coconut shells, walnut shells, apricot shells, jujube shells, etc. The activated carbon contains a large number of micropores. Activated carbon contains a large number of micropores, can adsorb organic pollutants and some inorganic substances, its adsorption capacity depends on the distribution of its own pore size and the molecular size of the adsorbed material.

Precautions on the use of activated carbon:

1, there is no national standard for the environmental performance of activated carbon, and consumers should purchase brand-name products with a certain degree of visibility.

2, the larger the confined space, the worse the purification effect of activated carbon. Activated carbon should be placed in the source of pollution and people often active places, such as closets, cabinets, sofas and so on.

3, activated carbon can not rely on exposure to unlimited use, timely replacement of new activated carbon can achieve the best removal effect.
