Its specification differes from 1to10mm,can make different bamboo charcoal bags with different size, shape and weight. 1.It can be used for absorbing moisture, deodorizing, maintaining freshness, resisting bacteriostasis, preventing worm. 2.Its major character is its entire function, long effect ,conviniece. It can adsorp and decompose harmful chemical substance in the air such as ammonia, benzene, alkaline air,TVOC gas and other smoke,humidity and odor. It can improve the air quality, the anoin it releases achieves so high that enables the air in the room to achieve the forest level quality. 3.Its excellent electrical conductivity can be cut off electromagnetism .Its spontaneous function is strong, the lifetime may amount to for a year. After its adsorption function declines it can be used to improve the earth condition to cause the soil soft, moderate acid and alkali, rich ventilation, and rich in micro element which is necessary to plant growing.
