Culligan Ultrafiltration Drinking Water System

Although this is better than not filtering your water at all it leaves a lot of other harmful things in your water. Heavy metals like lead and colbolt, chlorine, pharmaceuticals,floride,pesticides ect. A reverse osmosis system would be much better. There is also some gravity feed water filters out there that work were well. Some have filters that last up to 9,000 gllons.
