I've never heard of a neutralization filter.   How does it work.   The 
comment about acids and bases is unnecessarily patronizing (matronizing?).   To my 
poor uninformed mind, the only way I can see to neutralize something is to ADD 
another chemical, not filter anything out.   And why do we care, if we have 
micron level filtration, if the resulting water is acid?   Rainwater is 
"naturally" pH 5.5 after all, pretty acid.   Naturally, you don't want drinking water 
at, say, pH 3, but I don't see how a filter is going to address that problem.
