Carbon is not to be used on water of unknown microbiological content.
Bacteria love to 'breed' in carbon unless it is silver impregnated,
which there is very little of. His concern should be disinfection
(chlorine/chloramines) byproduct caused THMs (trihalomethanes).

Gary - and others... Thanks for all the great commentary so far.

Someone said that Mercury is not in "pipes".

Is that really true? I mean from my house to the acquifer - isn't it
very possible that some pipes or solder/welds could have mercury
content?

It is a moot point perhaps - because eventhough my water report does
not list Mercury (or Aresenic) contamination at my water supply, it
still could be there at very low levels.

I could spend ~$500 for a very thorough test of my water for all
detectable contaminants... To determine if there really is anything
detectable at my tap... But to me - even if I spend $150 for a
simpler test, it just makes sense to me to put that money into the
best carbon based filter I can buy. (E.g, it buys me insurance to
cover me on almost any serious non-radiological contaminant that is
there now and undetectable - or might show up in my water in the
future.)

Again - why Carbon? RO and distillation would remove Calcium,
Magnesium, and Fluoride. The relevance of magnesium intake to
cardivascular health cannot be ignored.

So that still makes me come back to my basic question... I agree that
MLM products are usually crap. In this instance, I have yet to see
any data that suggests Multi-Pure, which makes carbon filters that
will remove Mercury and pentavalent Arsenic, are "overpriced crap".
They are overpriced - but if they are worthy in terms of quality and
performance, I would consider them.
