Abstract
An activated carbon block filter including a unique bonded carbon mixture. The carbon mixture preferably includes a mean particle diameter in the range of about 60 microns to about 80 microns and a particle size distribution having less than 10% by weight of particles larger than 140 mesh and less than 10% by weight of particles smaller than 500 mesh. More preferably, the carbon mixture includes a mean particle diameter in the range of about 65 microns to about 75 microns. Even more preferably, the carbon mixture includes a mean particle diameter of about 70 microns and a particle size distribution having less than 7% by weight of particles larger than 140 mesh and less than 7.5% by weight of particles smaller than 500 mesh.
