Remove fluoride from your water unobtrusively with our four stage undersink filters.

No need to clutter your counter, these filters are designed to be installed underneath your sink.

Our three stage system includes two bone char and one carbon block filter.  The four stage system includes three bone char and one carbon block.  Because fluoride needs extended contact time with the filter, we have found that the three stage unit removes approximately 80% to 90% of the fluoride and the four stage unit removes approximately 99% of the fluoride.

On the four stage unit, you will receive two 2-stage units that connect together. Dimensions for each two-stage unit is:  Length: 10in, Depth: 5 in, Height: 13 in. The distance between each two stage unit can be any length you wish as this unit comes with an approx 18" piece of tubing that will connect each unit together with quick connect fittings. If you ever need to convert this to a countertop, flip the bracket, add the feet and you're good to go with a small conversion kit.  No need to buy a new system.

Bone Char is currently the most effective method to remove fluoride from drinking water. Bone char also removes heavy metals, pesticides and chlorine.  Our bone char is NSF61 Approved.

For more information on fluoride and Bone Char, visit our Fluoride Filters page.  You may also be interested in our What, Why and How of Fluoride Removal article.

If  you have a high amount of sediment turbidity in your water (usually from old pipes or frequent water line breakage) we highly encourage you to install a sediment pre filter on your system to avoid your new filter system from clogging and being ineffective.  We offer sediment pre filters as an option to eliminate any sediment or dirt debris that may clog your bone char filters. We strongly encourage you to purchase the pre filter if you have the above situation. Debris can clog the pores of these filters and may reduce the water pressure of your whole house Fluoride removal system. This may result in reduced effectiveness to remove fluoride. Promolife is not responsible if your filters clog soon after you install your fluoride removal water purifier.

Fluoride Filter Return Policy:  We are so confident in our fluoride systems that we are offering a money back guarantee.  If our filters don't remove or reduce your fluoride we will give you a full refund minus shipping.  Four stage point of use and four stage whole house systems are eligible for our money back guarantee.  

Terms of return policy:  Purchaser is responsible for sending the filters back before a refund will be given.  Customer must prove that fluoride is not being removed.  To do this, contact your local water company for a water report, which will let you know how much fluoride is originally in the water.  Then you must have your post-filtered water tested and submit the findings to Promolife along with your local water report.  If you do not see an 85% reduction in your fluoride levels you are eligible for our money back offer.

Please note:  Some people may have unusually high levels of fluoride that no filter system can adequately clear.  If levels exceed 2ppm we  can't guarantee the reduction promised.  For high levels we can offer assistance and recommendations but can not offer our money back guarantee.  Promolife reserves the right to refuse any fluoride test we believe was falsely performed. Some people experience a different taste after the initial install. This taste will go away. It is advised to run your water for 5 to 10 minutes once your unit is installed.
