Should You Filter Fluoride from Your Drinking Water? A Balanced Guide
August 09, 20232 min read
Fluoride is added to most Australian town water supplies at approximately 0.6–1.0 mg/L for dental health benefits. Whether to filter it out is a personal choice — here’s a balanced guide to help you decide.
What Is Fluoride and Why Is It in Australian Water?
Fluoride is a naturally occurring mineral. Australian state and territory health authorities add fluoride to town water supplies at low concentrations to reduce tooth decay — a practice endorsed by the Australian Dental Association and the National Health and Medical Research Council (NHMRC). The target concentration (0.6–1.0 mg/L) is set well below levels associated with adverse health effects.
Why Some People Choose to Filter It Out
Filtering fluoride is a personal choice, not a safety necessity for most Australians on town water. Common reasons people choose to filter it include:
Personal preference for controlling what’s in their drinking water
Households with infants, where formula preparation with fluoridated water may contribute to fluoride intake above recommended levels for that age group
Individuals with specific health conditions where their doctor has recommended reducing fluoride intake
General preference for the taste of water without added fluoride
Which Filters Actually Remove Fluoride?
Not all filters remove fluoride. The methods that work are:
Reverse osmosis — most effective (90–99% removal). See our RO Guide.
Standard carbon, KDF, ceramic, and sediment filters do not remove fluoride.
