Multi use charcoal filter material anti-odor. The colorful history of using carbon filtration. It is likely the earliest use was to remove impurities in smelted metal for the manufacture of bronze. The Egyptians appear to have been the first to use it in a medical way, to remove odors associated with infections. We know that sailors in the 16th through 18th centuries often stored their drinking water in barrels that had either been charred or smeared with charcoal on the inside to keep the water fresh on long voyages. In world war i, gas masks utilized charcoal to filter out some of the deadly gases used against the troops, but it was only effective against some of the toxins. The production and use of activated carbon grew dramatically only after world war ii, eventually leading to the development of modern activated carbon air and water filters.
