Abstract
A fluid purifier includes an enclosure provided with an inlet and an outlet, and a plurality of different carbon based purifying media disposed within the enclosure which are capable of removing different contaminants. In a non-limiting embodiment, the purifier includes three carbon-based materials ordered according to a specific sequence. In an aspect of the non-limiting embodiment, the material closer to the purifier inlet may include acid-impregnated carbons, the centrally-located material may include base-impregnated carbons, and the material closer to the outlet may include activated carbons. In a further non-limiting example, a method for purifying gas includes passing a gas through a carbon based purifying media including a first carbon based purifying media which is capable of removing a first species of contaminants, a second carbon based purifying media which is capable of removing a second species of contaminants, and a third carbon based purifying media which is capable of removing a third species of contaminants.
