Here's another question about Brita Water Filters. Presumably the efficiciency of the cartridges is affected by the amount of water they filter as well as the length of time they are in place? In which case, how many litres would one cartridge safely cope with? And is there really a maximum time required before changing it?

Calculate the overall lifetime dollar value of using a Brita (or similar filter) versus the costs and savings, including general impact on healthcare costs, etc, associated with using tap water. [more inside]

What's the deal with waterfilters? They're either sold like razors, with overpriced cartridges, (Pur
) or offered through cheesy networks of multi-level-marketing that look like something from the Davinci Code
After doing some googling I got interested in aquasana
then discovered they were spamming usenet as recently as 1999. That sets my spider sense a-tingling.
I have yet to find an unsponsored site with reviews of filters, but Dr. Weil
suggests a combination of charcoal and KDF for most filtering needs. Is there any reliable information out there, or do any of you have positive or negative experiences?
We're looking for something that will fit under our sink and make our highly mineralized well water taste good. Filtering out toxic crud is an added bonus. Thanks in advance!
addendum: This site
(the NSF) has some good data, but no price-per-gallon.
