Carbon only works on chlorine/chloramine at really slow flow rates,
so something like this would be wonderful if it really works.

Unfortunately, the ad reads a lot more like "snake-oil" than makes me 
comfortable.

Note how they carefully skirt around "chloramine." 90% of domestic 
supplies now use some or all chloramine, so removal of chlorine-only is 
only meaningful for a few rural systems any more (and many of those have 
natural chloramine from agriculture). Sounds like the chloramine might 
flow right through.

Whoever wrote the copy seems to be supplied with plenty of "brass." Can 
anyone explain exactly what is different about this product and the 
common Cu-Zn alloy (aka brass) used for plumbing fixtures for centuries? :-)
