Research Water Filters

We want to research water filters for the Little Green Expo. Which is the greenest & most socially responsible company, providing the best water filter for the price? If one of the top-runners is interested, we'll sell their filter. (I'm especially revved-up to do this because my house just bought a Pur filter that, on reading the box, only claims to reduce the cholorine taste and pretty much nothing else.

Volunteer needed: check consumer reports, ask at a couple coops (food coops, cooperative houses) to see if anyone has already researched this, check on enviro blogs --> creating a map of how to find out this kind of info would be useful for the next project. Check multi-pure (which is different from Pur)

or, post a reply if you have a favorite water filter.
