How activated carbon
Most active carbon, as used
for gas or vapor trapping, is made from coconut shell. The shells are heated to over
2,000Ã‚Â°C under high pressure, which causes fissures on the surface of the carbon, creating
a high quality, small pore activated carbon. The fissure system is extensive, creating a
very large surface area in a small package, and it is in these fissures that other gases
and particles are trapped. A single activated carbon filter has a flattened surface area
of a football field.
