Fluoride Removal

Fluoride Removal from Water in Fort Bend County

Why Utilities Add Fluoride

Community water fluoridation is the process of adjusting the amount of fluoride in drinking water to a level that prevents cavities, as the U.S. Centers for Disease Control and Prevention describes it. CDC calls fluoridation a cornerstone strategy for preventing tooth decay and says fluoridated water reduces cavities by about 25% in children and adults.

CDC does not mandate fluoridation. State and local governments decide whether to do it, so the answer can differ from one water system to the next.

The Federal Numbers

Three figures come up in every fluoride discussion, and they mean different things:

• 0.7 mg/L is the concentration recommended by the U.S. Public Health Service, which CDC says maximizes fluoride's oral health benefits while minimizing potential harms. It is a recommendation, not an enforceable standard.
• 4.0 mg/L is the U.S. Environmental Protection Agency's enforceable limit, the maximum contaminant level, set in 1986 and most recently reviewed in 2024.
• 2.0 mg/L is EPA's secondary standard, linked to tooth discoloration. It isn't federally enforceable, but EPA requires a special notice when a system exceeds it.

Where the Fluoride Debate Stands in 2026

Fluoridation policy is changing, and people disagree about it in good faith. Here is what official sources show as of November 2026:

• EPA is reviewing the science. In April 2025, EPA announced an expedited review of new scientific information on potential health risks of fluoride in drinking water, to inform its fluoride standard. It released a preliminary assessment plan for public comment in January 2026 and the protocol for its health assessment in August 2026, and it describes the work as coordinated with the U.S. Department of Health and Human Services.
• Health officials disagree. CDC still describes fluoridation as a cornerstone of preventing tooth decay. In November 2024, Florida's State Surgeon General recommended against community water fluoridation, citing neuropsychiatric risk associated with fluoride exposure, particularly in pregnant women and children, and the wide availability of other sources of fluoride.
• The federal recommendation still stands. In its January 2026 announcement, EPA stated that CDC's recommended level remains 0.7 mg/L and that the recommendation is advisory.
• Two states have ended fluoridation. Utah's H.B. 81, which took effect May 7, 2025, prohibits adding fluoride to public water systems. Florida's SB 700, which took effect July 1, 2025, bars additives that don't meet the state's definition of a water quality additive, and the Florida Department of Health describes Florida as the second state with a statewide ban on fluoridation.

We don't take a side. Whether your household drinks fluoridated water is your decision, and questions about your family's teeth belong with your dentist.

Does My Water Have Added Fluoride?

It depends on your water system. CDC points to the local water provider as the place to get information on fluoride levels in a community water system is the local water provider. Look for a fluoride row in your system's annual water quality report, or call the system and ask whether it adjusts fluoride and to what level. Our guide to reading your water quality report shows how to find your report and read its table.

Reducing Fluoride at the Kitchen Tap

If you decide you'd rather drink water with less fluoride, the usual tool is reverse osmosis at the tap. CDC's guide to choosing home water filters lists fluoride among the substances reverse osmosis filters may reduce, and NSF's listings include reverse osmosis systems certified to NSF/ANSI 58 for fluoride reduction.

Not every RO system carries that claim. Before you buy, check the system's performance data sheet and the certifier's listing for "fluoride reduction" on that exact model, and plan to replace its filters and membrane on the schedule its documents set.

Carbon Filters and Fluoride

CDC notes that pitcher filters and filters built into refrigerators often use activated carbon, mainly to improve the taste and smell of water. Carbon is the right media for chlorine and chloramine taste and odor, which is why our whole-home filtration uses it. But unless a filter's certification lists fluoride reduction, don't assume it reduces fluoride. That includes whole-home carbon systems, ours among them: we don't sell them for fluoride.

What an Under-Sink RO System Changes, and What It Doesn't

An under-sink reverse osmosis system treats the water at one faucet, usually at the kitchen sink, where you fill glasses and pots. Showers, laundry and the rest of the house still get your water system's water. That makes it a good fit for a decision about what your household drinks.

Reverse osmosis also removes most dissolved minerals, including calcium and magnesium, so the water tastes different from the tap; some systems add a remineralizing stage. On chloraminated water, the carbon pre-filters ahead of the membrane need to suit chloramine. If your water is hard, a water softener protects the rest of the house and helps the membrane last.
