How to Remove Fluoride from Drinking Water Ways to Remove Fluoride from Water * Reverse Osmosis Filtration This is used to purify several types of bottled water (not all), so some bottled waters are unfluoridated. Reverse osmosis systems are generally unaffordable for personal use. * Activated Alumina Defluoridation Filter These filters are used in locales where fluorosis is prevalent. They are relatively expensive (lowest price I saw was $30/filter) and require frequent replacement, but do offer an option for home water filtration. * Distillation Filtration There are commercially available distillation filters that can be purchased to remove fluoride from water. On a related note: When looking at bottled water, keep in mind that 'distilled water' does not imply that a product is suitable for drinking water and other undesirable impurities may be present. These Do NOT Remove Fluoride * Brita, Pur, and most other filters. Some websites about fluoride removal state otherwise, but I checked the product descriptions on the companies' websites to confirm that fluoride is left in the water. * Boiling Water This will concentrate the fluoride rather than reduce it. * Freezing Water From: http://www.healthcarealternatives.net/removingfluoride.htm There are three types of filtration media that will remove fluoride from water: bone char (a form of carbon), alumina (aluminum oxide) and a fluoride ion exchange resin. - Steve N -----Original Message----- From: sol [mailto:[email protected]] Sent: Saturday, February 14, 2009 9:55 AM To: [email protected] Subject: Re: CS>fluoride removed by distilling? Don't know about acid rain, but the weather patterns here have definitely changed. We no longer get the "polar express" arctic winds in the winter, so the last few winters have been very warm. The last 2 in particular. Not getting as much snow as we used ot either, so don't get high river in the springs either. We see more birds that used to stay far, far south, and some species that used to leave in winter now winter over here. And there is now a big water plant west of town that also reduces river flow, because water from here is sold east to the next town, and west to California. And the city built a "white water kayak park" and dredged the river, then dumped a bunch of large boulders held together with concrete into the river to create rapids. Geez Ken, as always you make me think. All of the above has been in place at least 5 years but with the warm winters maybe we are just now seeing full effects of so much disruption of the river. Before all this, there used to be hundreds of several species of warblers along the river in spring and summer, American Dippers in the natural rapids, Orioles nesting in the old, mostly dead cottonwoods (now all cut down, because they looked ugly and can't have that in the new kayak park), and there were muskrats in many of the natural sand bar islands in the river. Not all the birds and wildlife are gone of course, but all those are mostly gone or greatly reduced in numbers. I guess I'm an old grump but I preferred it all as it was, trashy vegetation, stagnant water and all. What we need is a hell of a good water year or a small earthquake to break the dam upstream (in rickety shape) and wash all this progress away. sol -- The Silver List is a moderated forum for discussing Colloidal Silver.
