Fluoride Water Filters
How to Remove Fluoride from Drinking Water
Fluoride is added to most US municipal water systems in the form of sodium fluoride, fluorosilicic acid, or sodium fluorosilicate in levels up to 1 ppm to prevent tooth decay. Over 4 ppm is considered unsafe and can damage teeth, wearing away the enamal. In recent years, some health professionals and scientists have questioned the safety of any amount of fluoride added to drinking water, however the majority find it safe and effective. Sodium fluoride is a bi-product of the aluminum industry. Fluoride is also naturally occuring and found in well water, and low levels in many foods (fish, meat, fruits and vegetables). Most municipal water systems add fluorosilicic acid (or hydrofluorosilicic acid) to the water, up to 1.4 ppm. In some states, like California, fluoride is naturally occuring and they add hydrofluorosilicic acid to reach the required level. In Los Angeles, they have 0.6 ppm naturally occuring fluoride and add 0.3 ppm to for a total of 0.9 ppm. Our fluoride water filter cartridge using aluminum oxide will remove up to 90 percent fluoride from your drinking water.
Methods to Remove Fluoride from Drinking Water
Activated alumina cartridges, reverse osmosis membrane filtration and bone char carbon filters are the three effective methods for removing fluoride from drinking water. Reverse osmosis and activated alumina can remove 80 to 90 percent of the fluoride, while bone char carbon, a special carbon made from animal bones, can remove from 50 to 60 percent of the fluoride. We are now offering bone char carbon GAC cartridges as an alternative to activated alumina (aluminum oxide).
If you search on the terms "fluoride removal" at the US Environmental Protection Agency site, .epa.gov, you will find several articles on removing fluoride. The accepted and most effective method is using aluminum oxide. Also, the process to remove fluoride from water was patented in 1936 by Harry. V. Churchill a chemist from Alcoa in New Kensington, PA: "Removal of fluorine from water", US Patent 2,059,553; filed October 2, 1933; granted November. 3, 1936 (using activated alumina). Referenced from fluoride-history.de/p-defluorid.htm#Churchill-2. For the history of fluoride see fluoride-history.de/.
Activated alumina, or aluminum oxide, is a naturally occuring inorganic compound that is chemically inert and non-toxic. It's also known as corundum, a form of aluminum oxide in crystalline form. Rubies and sapphires are prescious gem forms of corundum. Aluminum oxide (alumina) is a ceramic material that can be used as an insulator. It's also used a desiccant to absorb gases and odors, and it does a great job removing fluoride from water. For more information click to see the Aluminum Oxide article at Wikipedia.
Model CTD-F. Double Countertop Fluoride Water Filter with KDF/GAC (coconut shell) and Fluoride Pre-filter--sale $179.95 with free shipping. This countertop filter uses a fluoride removal cartridge with activated alumina (one of the best ways to remove fluoride) and our KDF/GAC cartridge for improved taste and contaminant removal. This system removes fluoride, chlorine, heavy metals (lead, arsenic), pesticides and more (see What's KDF). Requires a flow rate of 0.5 gpm or less to effectively remove the fluoride. A diverter valve replaces the aerator on your faucet (now a new more durable, long lasting, valve) - water is sent through the filter and out its own spout; a long reach lead free spout allowing for placement flexibility on your countertop. Includes chlorine test strips to verify when it's time to replace cartridge. 12" high, 5" diameter. 3 year prorated warranty on KDF/GAC cartridge, 5 year prorated on housings. Suggested Retail - $259, our sale $179.95 with our 3 year KDF/GAC cartridge plus free shipping (continental US only). ORDER NOW! VIEW CART/CHECKOUT. Click for Installation Instructions.
Note: The activated alumina cartridge can impart a slight metalic taste to the water for a week or two, but this will subside. You can avoid the metallic taste by going with the CTD-FB that uses bone char carbon cartridge.
New! Model CTD-FB using bone char carbon GAC to reduce fluoride from 40 to 60 percent. Same as above CTD-F. Suggested Retail - $259, our price $179.95 with our 3 year KDF/GAC cartridge plus free shipping (continental US only). ORDER NOW! VIEW CART/CHECKOUT.
Model UCD-F. This dual-cartridge under-counter filter uses a fluoride removal cartridge with activated alumina to effectively remove fluoride, for approximately one year. The second cartridge is our 12,000 gallon capacity KDF/GAC filter with coconut shell GAC (for improved taste and contaminant removal). It removes chlorine, heavy metals, pesticides and more (see What's KDF). The filter requires a flow rate of 0.5 gpm or less to effectively remove fluoride. Includes chlorine test strips to verify when it's time to replace the KDF/GAC cartridge. Includes standard faucet, tubing and water line hook up. 12" tall, 10" wide, 5" deep. 3 year prorated warranty on KDF/GAC cartridge, 5 year prorated on housings.
