Abstract
The invention provides a low-resistance gas adsorption filter provided with an activated carbon bed of bulk density less than 0.6 gram/cubic centimeter, the activated carbon bed being free of chromium 6+ salt, the filter being characterized by a gas holding capacity exceeding 300,000 milligram Dimethyl-methyl Phosphonate (DMMP)×minute/cubic meter and an airflow resistance such that the numerical value of air flow resistance in Pascal per millimeter of bed thickness does not exceed by more than 50% the numerical value of air velocity in centimeters per second.
