Yes. Bottled water labeled purified (usually by reverse osmosis) or distilled typically contains little to no fluoride, so it is the easiest fluoride-free option to find. Spring and mineral waters carry natural fluoride that varies by source, and any bottled water with fluoride added must say so on the label. For an exact number, check the brand's published water quality report.
How Much Fluoride Is in Bottled Water?
Fluoride in bottled water comes from two places: the source and what the bottler adds. Groundwater picks up natural fluoride from rock, so spring, mineral and artesian waters can range from barely detectable to well above tap-water levels depending on where they come from. Purified waters start from a municipal or well source, then go through reverse osmosis or distillation, which strip out most dissolved minerals, fluoride included.
For context, here are the federal reference points:
- 0.7 mg/L is the U.S. Public Health Service recommended level for community water fluoridation, and FDA's limit for bottled water with fluoride added.
- 2.0 mg/L is EPA's secondary (non-enforceable) standard, set to limit dental fluorosis.
- 4.0 mg/L is EPA's enforceable maximum contaminant level for public water systems, set to protect against skeletal fluorosis.

Which Bottled Waters Are Fluoride-Free?
Rather than trusting a list that can go out of date, use the type of water as your guide, then confirm with the brand.
| Type of bottled water | Typical fluoride | What to check |
|---|---|---|
| Distilled | Essentially none | Look for "distilled" on the label |
| Purified (reverse osmosis or deionized) | Very low, often not detectable | Label says "purified"; check for added minerals or fluoride |
| Vapor-distilled with electrolytes | Very low | Electrolytes are added for taste, not fluoride |
| Spring water | Varies by source | Brand water quality report |
| Mineral or artesian water | Varies, can be higher | Brand water quality report |
| "Fluoride added" or nursery water | Added on purpose (up to 0.7 mg/L) | Stated on the label |
Widely sold purified brands such as Aquafina (reverse osmosis) and vapor-distilled waters such as Smartwater fall in the very-low group, as do store-brand distilled gallons. Bottlers can change sources and processes, so check the current report if fluoride matters to you.
How to Identify Fluoride-Free Options
- Read the front label. "Distilled," "purified," "reverse osmosis" or "deionized" are your best signs.
- Read the ingredient list. If fluoride was added, it has to be listed. Products marketed for babies are the most common ones with added fluoride.
- Check the water quality report. Most major brands publish an annual report on their website listing measured fluoride. Look for "ND" (not detected) or a value below 0.1 mg/L.
- Watch "from a municipal source." That is fine if the water was then purified. It only means the starting water was city tap water.
Fluoride and Health: What CDC and EPA Say
The CDC supports community water fluoridation at 0.7 mg/L because it reduces tooth decay. At the same time, too much fluoride while teeth are forming can cause dental fluorosis (white spots or streaks on teeth), which is why the CDC notes that parents can mix infant formula with low-fluoride bottled water labeled purified, distilled, deionized or demineralized.
At much higher long-term levels, fluoride can affect bones (skeletal fluorosis), which is what EPA's 4.0 mg/L limit protects against. In 2024 the National Toxicology Program reported, with moderate confidence, that fluoride exposures above 1.5 mg/L are associated with lower IQ in children; it did not reach that conclusion for the 0.7 mg/L used in fluoridated U.S. water. Some families still choose to limit fluoride, and that is a personal decision. Ask your dentist or pediatrician if you have questions about your family's total fluoride intake.
Fluoride-Free Water at Home (Cheaper Than Bottles)
If you drink a lot of bottled water to avoid fluoride, treating your own water usually costs less and cuts the plastic. Not every filter works, though:
- Reverse osmosis (under-sink): reduces most fluoride at the kitchen tap. It is the most common choice for drinking and cooking water. Know the tradeoffs first: see reverse osmosis drawbacks .
- Bone char or activated alumina media: both adsorb fluoride. Our whole-house catalytic bone char carbon filter treats every tap and shower, and our SoftPro Elite and ECO softeners can be ordered with the Gold+ whole-house fluoride filtration option. Learn how the media works in bone char water filters explained .
- Distillation: removes nearly all fluoride but is slow and uses electricity.
- What does not work well: standard activated carbon pitchers and refrigerator filters remove very little fluoride, and a water softener does not remove fluoride at all.
If you already have a softener, a fluoride filter can be added alongside it; see combining a softener with RO or other filters . For bathing and showers, read do I need to filter fluoride out of bath water? and our guide to shower filters that remove fluoride .

Frequently Asked Questions
Which bottled water has no fluoride?
Distilled water and purified water made by reverse osmosis or deionization have little to no fluoride. Aquafina, vapor-distilled waters like Smartwater and store-brand distilled water are common examples. Spring and mineral waters vary, so check the brand’s water quality report for the measured level.
Is Aquafina fluoride free?
Aquafina is purified with reverse osmosis, which removes most fluoride, so it is generally treated as a fluoride-free option. Fluoride is not added. For the current measured value, check the water quality report PepsiCo publishes for Aquafina.
Does spring water have fluoride?
Usually some, because spring water picks up natural fluoride from the ground. The amount depends on the source and can range from barely detectable to above tap-water levels. Look up the brand’s quality report rather than assuming spring water is fluoride-free.
How do I get fluoride-free water at home?
The most practical options are an under-sink reverse osmosis system for drinking water, or a whole-house bone char or activated alumina filter for every tap. Distillers also work but are slow. Regular carbon pitchers, fridge filters and water softeners do not remove much fluoride.
Do Brita or refrigerator filters remove fluoride?
Standard activated carbon filters are made for chlorine, taste and odor, and remove very little fluoride. Look for a filter specifically rated for fluoride reduction, or use reverse osmosis.
What water should I use for baby formula to limit fluoride?
The CDC says you can use low-fluoride bottled water labeled purified, distilled, deionized or demineralized to reduce the chance of dental fluorosis. Using fluoridated tap water is also considered safe. Talk with your pediatrician about what is right for your baby.
