How to Remove Fluoride from Drinking Water

Preventing Fluorosis

By Anne Marie Helmenstine, Ph.D.

Most people are aware that there is a controversy surrounding public fluoridation of drinking water. Here is a list of ways to obtain drinking water without fluoride. In addition, I've listed water purification methods which do not remove fluoride from 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
    Freezing water does not affect the concentration of fluoride.

Steps to Reduce Fluoride Exposure

  • Don't take fluoride supplements.

  • Read labels on bottled beverages.
    Unless they are made using distilled or reverse-osmosis water, they are probably made with fluoridated public water.

  • Consider using unfluoridated toothpaste.

  • Avoid drinking black or red tea.
    They come from two different types of plants, but both leaves naturally contain high amounts of fluorine.

  • Be wary of tinned fish and canned food items.
    Fluoride may be used as a preservative.

  • Avoid black or red rock salt or items containing black or red rock salt.

  • Avoid using chewing tobacco.

  • Avoid long term use of medication that contains fluorine.
    Certain antidepressants and medications for osteoporosis contain fluorine.
