The 102-160 is particularly well suited for chloramine removal. The cartridge removes contaminants from water by absorption, adsorption, ion exchange, sequestration, or other mechanism, or any combination of these. With the use of a two-stage design, water is to be purified by first passing through filtration media, and a second stage containing a porous filtration block. Moreover, by careful selection of the particle size of the purifying media in the first stage, a system can be obtained that is 99% dust free. This allows water to flow through the purification system with much lower pressure drops than are achievable with existing systems.
