There Are Four Proven Methods for Removing Fluoride:

Reverse Osmosis:

  • Removes up to 99% of the fluoride and 65 other contaminants, including lead, fluoride, chlorine, dissolved salts, and more.
  • Forces water through a series of semi-permeable membranes
  • Fluoride is a very small Ion (atomic #9), so it is very difficult to remove
  • Semi-permeable pores utilized are much smaller than fluoride ions, which prevent passage
  • During this process, larger fluoride & other contaminants are filtered out and flushed away
  • It is critical to use high-grade US-made membranes, to ensure the most effective removal of fluoride


  • Removes 95% of fluoride
  • Uses resin for Ion exchange to remove fluoride and other contaminants
    • Replaces positive & negative-charged contaminant molecules with positive hydrogen & negative-charged hydroxyl molecules.
  • Processes water at a high rate
  • It is critical to use high-grade US-made resin, to ensure the most effective removal of fluoride

Activated Alumina:

  • Absorbs 85% of fluoride and contaminants
    • Attracts fluoride molecules (and other toxin)
  • Becomes saturated with fluoride and toxins rather quickly and can no longer filter water effectively
    • Filter change required more frequently than other solutions
  • Very slow process of producing clean water
    • Produces water at a rate of less than 1⁄4 gallon per minute, which is only 2 ounces
    • If the alumina filters water more quickly than this, fluoride and toxins will not be absorbed
  • Due to the extremely slow process, this is not an ideal solution for most households or business
  • It is critical to use high-grade US-made Activated Alumina to ensure effective absorption of fluoride

Bone Char (non-Vegan):

  • Absorbs 85% of fluoride
  • aka Brimac, absorbs fluoride
  • Created by using thoroughly cleaned bovine (cow) bones
    • Bones are dried in the sun for at least 90 days
    • The bones are then heated 1472° F in the absence of oxygen
  • The result is a char made of 80% phosphate of calcium, 10% carbon and 10% calcium carbonate.
  • It has a very porous ionic surface, which loves adsorbing things like fluoride.
  • Brimac works best at a slightly acidic pH and may not work as well with hard water
  • Requires pre-filters to remove heavy metals & other contaminants to effectively absorb fluoride
  • Due to the lengthy process to produce, it can be rather costly, difficult to guarantee quality & acquire
  • It is critical to use high-grade US-made Bone Char to ensure effective absorption of fluoride

Here at the Water Market, we not only use Reverse Osmosis, which is the most effective way for removing Fluoride, other harmful chemicals & pharmaceuticals, as an extra precautionary measure, we also use Deionizing to remove Fluoride and harmful chemicals.
