I had heard that the filters will not get DP>everything out of the water and that the water should be treated with DP>pills or drops before drinking. Is there a filter that will tke ALL DP>harmeful things out of the water? It sure would DP>be nice to drink cold water from a stream thru a filter instead of DP>boiling and treating. Excuse me for jumping in. My suggestion would be to disinfect the water first and then filter it. I would only do this with water that looks clear to begin with. If the water is dirty the disinfection will require more CL2 (or whatever you use). Use a chlorine residual tester to check the demand, this way you can add only what is needed to insure proper disinfection. I am not aware of any filter that can safely disinfect the water, but I can think of many filters that will get the residual CL2 out. Try to give the disinfectant as much time to react with the water as possible, that way you wont need to add as much CL2. The water district I work for maintains a chlorine residual of about .6 ppm throughout the distribution system. And thats being on the safe side. At that level I cant even notice it. But I live in So Cal so that probably makes me less sensitive to tastes and oders. I have quite a few books regarding water treatment, if you would like me to look up something specific let me know.
