Filtering fluoride from tap water

Researchers examined how well water filter pitchers may be capable of removing certain minerals such as fluoride from tap water.

In a study published in the Journal of Public Health Dentistry, the researchers obtained nine water filter pitchers and examined the mineral concentrations of fluoride, calcium, magnesium and sodium in tap water prior to and following filtration.

The researchers found that two of the filters decreased fluoride concentrations, seven of them decreased calcium concentrations, three filters decreased magnesium concentrations and one filter decreased sodium concentrations. Further, two of the filters increased potassium concentrations and one of the filters increased sodium concentrations. One of the filters capable of reducing fluoride concentrations was found to be the most effective at removing all minerals compared with the other filters; however, none of them were able to completely remove fluoride from tap water.

The study authors concluded that water filter pitcher products vary in their ability to filter certain minerals, including fluoride, and that consumers should research the capabilities and limitations of the water filter pitchers that they purchase.
