Nano Silver Activated Carbon Filter

Nano Silver Activated Carbon

Through the hi-tech nano-technology, the activity of silver ion is enhanced. After the activated carbon combining with nano-silver ions, its absorption capability on organic polymers is increased several times and disinfection efficiency is enhanced more than 2000 times comparing to the result from the silver added and silver impregnated carbons and several ten-times better than the chlorine effect in the tap water.


Absorb the residues of agricultural and chemicals elements. Inhibit the growth of bacteria more than 650 kinds. It is more efficient and more reliable than Ultraviolet (UV) Technology.


a-king nano-silver activated carbon sterilization principle..

Nano silver particles can penetrate bacteria cell walls easily


After being nanosized, the silver ion will be activated and thus carries positive charge, It can adsorb the microorganism with negative charge. Then, the activated silver ion can effectively break through the cell wall and the cell membrane of the microorganism

Silver ion will penetrate and warp over bacteria 

The puncture causes deformation of the structure of protein enzyme in microorganism cells, which leads to the slowdown of its metabolism, and eventually suffocation to death.

When bacterium breaks and dies, the silver ion well float out the cell 

Most significantly, activated silver ion will be released from dead microorganism after the microorganism was killed by silver ion. The action will be repeated until all living microorganism is exterminated. That proves Nano Silver has a long-term anti-microbial effect.
