Methods to Remove Fluoride from Drinking Water
Activated alumina cartridges and reverse osmosis membrane filtration systems are the only two methods for removing fluoride from drinking water. Some companies claim that carbon filters will remove fluoride, but this is not correct. Also, all our fluoride systems use dual stage filters with activated alumina in the first stage and KDF/GAC in the second. We use the KDF/GAC cartridge to remove any activated alumina that may get into your water. Our Doulton ceramic cartridge will also reduce aluminum in your water and should be installed after the fluoride cartridge. This would call for using the triple filter system, UCT-C-F or CTT-C-F listed below. Beware of companies selling a single stage filter with just activated alumina. This setup doesn't protect against activated alumina in your water.
In a recent lab test dated 10-06-2008 at the Michigan Department of Environmental Services in Lansing, the results show no aluminum present in the sample water. The water sample was from our UCD-F filter, running at 0.5 gallons per minute. The cartridge had been broken in by running water through it for 20 minutes, and the sample was taken after one month of use. The water passes through the fluoriide removal cartridge made up of activated alumina (aluminum oxide) and then through the KDF/GAC media. We are happy to say that no aluminum was present.

Methods to Remove Fluoride from Drinking Water
Activated alumina cartridges and reverse osmosis water filters are two methods for removing up to 90 percent of the fluoride from drinking water. The aluminum oxide absorbs the fluoride ion, however water flow rate must be at 0.5 gallons per minute for this method to be effective. All our fluoride filters use dual stage systems with activated alumina in the first stage and KDF/GAC in the second. KDF/GAC will remove heavy metals, and is used to remove any aluminum that may get into your water. Fluoride is also naturally occuring and found in well water, and low levels in many foods (fish, meat, fruits and vegetables). It is also a waste product of the aluminum industry.
Fluoride is added in the form of sodium fluoride, fluorosilicic acid, or sodium fluorosilicate to most municipal water systems in the US (levels up to 1 ppm) to prevent tooth decay. Over 4 ppm is considered unsafe. In recent years, some health professionals and scientists have questioned its safety in drinking water, however the majority find it safe and effective. For those who are chemical sensitive, or want to remove fluoride, we offer several countertop & under-counter filtering systems for fluoride as well as other contaminants including lead, arsenic, THMs, VOCs, bacteria, nitrate, sodium, chloramines, sediment and cysts (cryptosporidium). Our Doulton ceramic cartridge will also reduce aluminum and can be installed after the fluoride cartridge.
