[VAL] Re: EverPure water filter, take 2

[Chris Koehn <timberguides@xxxxxxxxx>]

Here's a good link to a site that compares leading filter 
manufacturers, cost per gallon, and effectiveness on the most common 
contaminants:

<http://www.waterfiltercomparisons.net/WaterFilter_Comparison.cfm>

There is one EverPure model tested, which appears to be comparable to 
the QC2 that was standard equip on our A/S.
The bottom line is that some filter types are better at some 
contaminants, while others are better at other types. These can be 
generally grouped into  "chemical" contaminants" and "bacteriological 
contaminants." The primary difference being particulate size: chemicals 
can't be filtered out simply by passing water through a small enough 
filter media. So if you are getting water in rural areas where 
bacteriological contamination (such as giardia) is an issue, filtration 
requirements are different than they would be in places where 
industrial or chemical contamination (such as atrizine in farm areas, 
or MTBE, around fuel sources or refineries) are the problem.

For the record, there are very few in the scientific community that 
would recommend drinking distilled water on a regular basis. 
Distillation removes all trace minerals. Further, it changes the Ph, 
which can cause minerals such as calcium to be leached from the bones 
and teeth. Re verse Osmosis treated water has similar problems.
