I live in the UK (North Wales)the drinking water smells like it came from a swimming pool so much chlorine, so I fitted two small filters under the sink, about 2 inches dia and 9 inches long, the first one is a micro porus ceramic filter removes particles and all the lepto type spores and cysts, the second one is a carbon block filter.  Carbon block offeres a greater surface area than particles. the complete set up including a small tap was around £50 the water is a good as any bottled water and therre is no chlorine, chlorine has been linked to colon cancer so best avoided.
