Brita filters seem expensive and wasteful. Instead, where can I buy my own cation exchange resin (preferably in the UK)? [more inside]

Does Brita filtered water work for making wine? My experiment got no yeast fermentation in four batches of wine using Brita filtered water and great yeast fermentation in three batches of unfiltered tap made similarly as a control.

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?

I have a brita filter pitcher and I bought a 6 pack of filters almost a year ago(to save $$). The past 2 or 3 filters I put in there have had water run through them really fast compared to all the other filters I've used. Could there be a problem with the filters? Have they re engineered them to filter water faster? Are they even working?

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]

How do they work? There is much information about the fact that you need to keep the filter (partially comprised of activated charcoal, from what I can gather) in contact with water at all times. How does activated charcoal actually filter impurities? [More Inside] [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.
