Just wondering if anyone has delved much into purification and/or filtration of their tap water and how they go about it. I've used a Brita filter system but it seems they're a bit rubbish really. Have got a Berkey system on the way, which claims to remove everything nasty, yet retain the mineral content, which seems a little implausible, but who knows. Not me.
Are there are any simple home water-testing kits beyond the TDS/EC meters that address mineral content rather than just non-specific dissolved solids? Also, if mineral replacement is required, can anyone recommend a good product/method?
