Abstract:
1. A filter for removing contaminants from water, said filter comprising: a first porous filter part comprising an active carbon in a high-molecular low-melt index polymeric binder; an inlet for directing water to be filtered to the first porous filter part; and an outlet for directing water filtered by passage through the first porous filter part to a point of use, wherein the polymeric binder comprises a porous polymer with a melt index of from 1.1–2.3 g/10 min (ASTM D1238, 190° C., 15 kg Load), wherein the active carbon comprises two different particulate active carbons consisting of a) a first particulate active carbon having a larger particle diameter capable of passing through a mesh of 60–100 and b) a second particulate active carbon having a smaller particle diameter capable of passing through a mesh of larger than 100, with the first and second particulate active carbon being mixed in a ratio of 1:4–4:1, wherein the first porous filter part comprises polymeric binder in an amount of 10–25% by weight to active carbon and the first porous filter part has a density of 0.5–0.65 g/cm
