The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for forming a filter medium, comprising:
providing activated carbon and nitrogen enriched plastic binder;
mixing the activated carbon and the nitrogen enriched plastic binder; and
heating the activated carbon and the nitrogen enriched plastic binder, the activated carbon bound to the nitrogen enriched plastic binder after said step of heating such that the activated carbon and the nitrogen enriched plastic binder form a filter medium block.
2. The method of claim 1, wherein the nitrogen enriched plastic binder comprises at least one of polyurethane and urea formaldehyde.
3. The method of claim 2, wherein the nitrogen enriched plastic binder further comprises polyethylene.
4. The method of claim 1, wherein the filter medium block comprises at least sixty percent activated carbon by weight and no more than ninety percent activated carbon by weight after said step of heating.
5. The method of claim 4, wherein the filter medium block comprises at least ten percent nitrogen enriched plastic binder by weight and no more than forty percent nitrogen enriched plastic binder by weight after said step of heating.
6. The method of claim 1, wherein the activated carbon comprises catalytic activated carbon.
7. The method of claim 1, further comprising positioning the filter medium block within a filter cartridge after said step of heating.
8. The method of claim 7, further comprising directing water through the filter medium block within the filter cartridge, the filter medium block removing chloramine from the water flowing through the filter medium block at said step of directing, nitrogen from the nitrogen enriched plastic binder reacting with chloramine from the water flowing through the filter medium block at said step of directing.
9. A filter cartridge, comprising:
a casing defining an interior volume;
a filter medium positioned within the interior volume of the casing, the filter medium comprising activated carbon dispersed within a plastic binder, the plastic binder comprising at least one of polyurethane and urea formaldehyde.
10. The filter cartridge of claim 9, wherein the plastic binder further comprises polyethylene.
