Hello, I'm searching for a water filter than can remove fluoride, chlorine, bacteria, heavy metals, and if possible, nonorganic toxic chemicals. I would prefer a stand-alone unit because I am living in an apartment and will be moving soon so I don't feel like dealing with installation, but if the best unit needs to be installed, I'll definitely consider it.
I have been looking at Berkey gravity filters and am thinking of buying the Big Berkey or Royal Berkey with two fluoride filters. If you have any experience with these filters or any others, please let me know.
Fluoride is one of the hardest things to remove from water. I've done a bit of research, and some sources say that only distillation or reverse osmosis will get it out, and other sources say that other methods will work, but then the first sources say that those methods only work for a short time or with acidic water.
There's a great company in Seattle called Custom Pure that sells multi-stage filters using ionizing resin and then carbon.
FWIW, Im planning on getting a berkey. Ive heard so many good things about it and to my knowledge its the only one that will get rid of all those things you stated. I have no personal experience with it yet.
