I know some of them do their job in an eco-friendly way with lilly pads, etc, but my local water treatment plant definitely doesn't. I do my best not to support things like this so I've taken my house off municipal water. I'm planning to dig a well and run the water through a whole-house water filter to purify it. I'm worried that the companies that make the filters don't use environmentally friendly practices though, does anybody know which of the companies listed here would be best? I'm trying to do the right thing here!
