Which Water Filter Brands Offer Fluoride-Removal Products?

A short list of brands sell products built to actually remove fluoride, and nearly all of them rely on one of three methods: reverse osmosis, distillation, or activated alumina and specialty ion-exchange media. A standard carbon filter, the kind used in most pitchers and refrigerator dispensers, is not built for this job and typically lets most fluoride pass straight through.

Brands selling reverse osmosis systems that address fluoride include Viomi, APEC, iSpring, Waterdrop, and AquaTru. Epic Water Filters and Clearly Filtered build pitchers specifically around fluoride reduction using nanofiber, carbon fiber block, or other specialty adsorptive media instead of plain carbon. Berkey removes fluoride only when its gravity systems are paired with the separate PF-2 filter set, sold on top of the base system. Whole-house fluoride reduction is a narrower category, with SoftPro among the few brands offering a dedicated system.

Below is what actually separates these brands from the ones that don’t touch fluoride at all, how to verify a specific product’s claim before you buy, and where Viomi’s reverse osmosis systems fit if fluoride is one of several things on your list.

Why Most Water Filters Don’t Remove Fluoride

Standard activated carbon works by adsorption: contaminant molecules stick to the surface of the carbon as water passes through. It’s effective against chlorine, many taste and odor compounds, and some organic chemicals.

Fluoride doesn’t behave the same way. It exists in water as a small, highly soluble negative ion that doesn’t bind well to a carbon surface. A 2008 peer-reviewed study testing both carbon-block and hollow-fiber membrane filters on fluoridated tap water found neither method removed a meaningful amount of fluoride, and independent lab testing of popular carbon pitchers has repeatedly shown the same pattern: most of the fluoride that goes in comes back out.

That’s the gap this article is about. “Water filter” and “fluoride filter” are not the same claim, and a lot of well-known, genuinely useful filters (Brita and PUR pitchers among them) fall into the first category without making any promise about the second. Checking a product’s actual spec sheet, not just the words “water filter” on the box, is the only reliable way to know which one you’re buying.

What Actually Removes Fluoride

Three technologies have a real track record for fluoride reduction. Each works differently, and each comes with tradeoffs worth knowing before you pick one.

Reverse Osmosis (RO)

An RO system forces water through a semi-permeable membrane with pores small enough to block dissolved ions, including fluoride, along with lead, arsenic, PFAS, and most of what raises a water’s total dissolved solids (TDS) reading. Because the membrane isn’t selectively targeting fluoride, fluoride reduction comes as part of the same process that lowers overall TDS. Published fluoride reduction figures for specific RO systems commonly fall somewhere in a 90 to 98 percent range, but that range depends heavily on the specific membrane, water pressure, and how much fluoride was in the source water to begin with; it isn’t a guaranteed figure for any given RO system.

A system’s overall TDS reduction percentage and its fluoride reduction percentage are related but not interchangeable. Fluoride is only one of many ions that contribute to a TDS reading, and a membrane doesn’t necessarily reject every one of those ions at the same rate, so a published TDS number on its own isn’t a reliable way to estimate a product’s fluoride performance. The tradeoff with RO in general is water waste (most residential RO systems reject some water down the drain, though modern tankless designs have cut that ratio significantly) and the need for either an under-sink connection or a countertop unit with a tank to refill.

Distillation

A distiller boils water into steam, then condenses it back into liquid, leaving fluoride and most other dissolved minerals and contaminants behind in the boiling chamber. It’s one of the most complete removal methods available for home use, and it doesn’t rely on a membrane that can degrade over time.

The catch is speed and scale: distillers process water slowly, batch by batch, which makes them a reasonable fit for drinking and cooking water but impractical as a whole-kitchen or whole-house solution. If you’re shopping for a countertop distiller specifically, look for a spec sheet that lists a fluoride reduction figure rather than assuming the general technology description covers it.

Activated Alumina and Specialty Ion-Exchange Media

Activated alumina is a porous aluminum oxide material that adsorbs fluoride ions directly, unlike standard carbon. It’s the basis for most pitcher and cartridge filters that are marketed specifically for fluoride removal, and it’s also used in the add-on elements some gravity systems sell separately.

Performance depends heavily on contact time (fluoride needs longer exposure to the media than chlorine does, which is why pitcher-style filters that hold water for a while tend to outperform quick-pass formats like straw filters or faucet attachments) and on your water’s pH, since most activated alumina media works best in a slightly acidic to neutral range.

Water Filter Brands That Offer Fluoride-Removal Products

Under-Sink and Countertop RO Systems

This is the category with the widest brand selection and the deepest contaminant coverage, since an RO membrane addresses fluoride as part of a broader reduction in dissolved solids rather than as a single-purpose add-on.

Viomi sells three RO systems on water.viomi.com that list fluoride among the contaminants their membranes reduce: the Viomi M1, and the Viomi V6 PRO and Viomi V8 PRO. More on these below.

APEC’s Ultimate series (including the RO-90) is WQA-certified and lists fluoride alongside arsenic, barium, cadmium, chromium, copper, and lead as contaminants the system reduces.

iSpring’s RCC7AK, an NSF/ANSI 58-certified under-sink RO system, publishes a fluoride reduction figure on its own spec sheet, rather than folding it into a general contaminant list.

Waterdrop’s G3P800, a tankless 800-GPD under-sink system certified to NSF/ANSI 42, 53, 58, and 372, lists fluoride reduction alongside PFAS and heavy metals in its published specs.

AquaTru takes a countertop approach with no plumbing connection required. Its Classic and newer under-sink models are IAPMO-certified to NSF standards, with fluoride included among the roughly 84 contaminants the company states its systems are tested to reduce.

Where Viomi’s RO Systems Fit

Viomi’s M1 ($799.99) is a tankless, under-sink alkaline RO system with 9-stage filtration and a 0.0001-micron membrane, built around a touchscreen faucet that shows live TDS and filter-life readings. For a household with kids or pets, that screen answers two questions that usually rely on guesswork: whether the filter still has useful life left, instead of tracking a change date on a calendar, and whether the water coming out right now is actually meeting a low-TDS target, instead of just assuming the system is doing its job. It’s NSF/ANSI 58 certified for TDS reduction and NSF/ANSI 42 certified for chlorine, taste, and odor. The product page states the system “can effectively reduce TDS, hexavalent chromium, fluoride, lead, iron, cadmium” and other dissolved contaminants.

The Viomi V6 PRO and Viomi V8 PRO (600 and 800 GPD, priced as of this writing at $379.99 and $479.99 respectively, using Viomi’s regular prices as the comparison standard) are Viomi’s tankless under-sink RO line, both certified to NSF/ANSI 42, 53, and 58 performance standards plus NSF/ANSI 372 for lead-free materials. Their product pages list the same language: the RO membrane is built to reduce fluoride alongside PFAS (PFOA/PFOS), lead, copper, arsenic, and nitrate. SGS challenge testing per NSF/ANSI 58-2023 backs that claim with a specific number: fluoride reduction measured above 99.9% with a new filter, holding at 99.40% (Viomi V6 PRO) and 97.91% (Viomi V8 PRO) after 7,300 liters, the point SGS used to represent the end of the filter’s rated service life. Since promotional pricing changes, check water.viomi.com directly for the current price before buying.

Viomi lists fluoride among the contaminants these systems are designed to reduce, as part of their broader reduction in dissolved solids alongside PFAS, lead, and TDS. For the Viomi V6 PRO and Viomi V8 PRO, that claim carries a specific, independently tested number: SGS lab testing puts fluoride reduction above 99% with a new filter. The Viomi M1 carries the same kind of independently verified numbers for PFOS, PFOA, and lead, a level of third-party-verified specificity that most single-purpose fluoride pitchers don’t match outside of fluoride itself.

The Viomi M1 combines reverse osmosis with remineralization and a touchscreen faucet that displays live water-quality information.

The Viomi V8 PRO combines 9-stage RO filtration with a smart faucet and app-connected filter monitoring.

If you’re also dealing with PFAS or lead alongside fluoride concerns, an RO system addresses all three with one install instead of stacking a separate fluoride cartridge onto an existing filter. That’s the practical case for Viomi’s under-sink line over a pitcher-based fix: one 9-stage system instead of managing multiple single-purpose filters. Where it doesn’t fit as well is a rental or a tight cabinet with no room for a tankless unit and its drain connection, in which case a countertop RO or a specialty pitcher (below) is the more realistic starting point.

Specialty Pitchers Built Around Fluoride

Epic Water Filters currently sells the Pure XP pitcher, built around its CoreXchange nanofiber and carbon fiber block filtration technology rather than a plain carbon cartridge, marketed specifically for fluoride reduction rather than as a general-purpose upgrade. (Epic previously sold a separate Pure model built on an activated alumina blend; that’s historical information only, since Epic no longer sells it as a standalone product and its old product page now redirects to Pure XP.) The Pure XP has been recognized in third-party testing roundups specifically for fluoride and PFAS performance.

Clearly Filtered uses a proprietary adsorptive media it calls Affinity Filtration, certified to NSF/ANSI 42 and 372; its broader contaminant claims, including fluoride, are based on independent lab testing rather than a 53 lead certification. Clearly Filtered’s own published performance data shows fluoride reduced from 2.18 mg/L to less than 0.01 mg/L, a greater than 99.54 percent reduction, under QFT/IAPMO testing conducted in New Jersey.

Gravity Systems: Berkey’s Add-On Approach

Standard Black Berkey elements are not designed to remove fluoride on their own. Berkey sells a separate PF-2 element specifically for fluoride and arsenic reduction, installed underneath the primary elements in the lower chamber, one PF-2 per Black Berkey element already in use. Under optimal source-water pH (the manufacturer recommends 5 to 7), Berkey states the PF-2 add-on can reduce fluoride by more than 99.75 percent. It’s a system you add to an existing Berkey, not something that comes standard.

Whole-House Fluoride Reduction

Point-of-entry (whole-house) fluoride removal is uncommon, since most fluoride-reduction media works best with the longer contact time a point-of-use system allows. SoftPro is one of the few brands selling a dedicated whole-house fluoride filter, built around a specialized media tank rather than the carbon or sediment media used in typical whole-house filtration.

Popular Brands That Don’t Remove Much Fluoride

Brita and PUR pitchers are certified for chlorine, taste, and odor reduction, and select higher-tier models from both Brita (e.g., Elite/Longlast+) and PUR add NSF/ANSI 53 lead-reduction certification. Neither brand markets its standard carbon cartridges as a fluoride solution, and independent testing consistently shows minimal fluoride reduction from this filter type. If fluoride is a specific concern, a standard carbon pitcher from either brand is not the product to reach for, regardless of how effective it is at what it’s actually built for.

Fluoride-Removal Options at a Glance

The “Fluoride Handling” column mixes different strengths of evidence: some numbers come from independent certification testing (NSF/WQA/IAPMO), some are brand-published lab results, and some are simply “fluoride” named on a contaminant list with no tested figure attached. Certified and independently tested numbers carry more weight than a brand’s own claim, and a bare contaminant listing carries the least.

How to Confirm a Specific Product Actually Removes Fluoride

A general certification badge on its own doesn’t answer the question. NSF/ANSI 58 covers reverse osmosis systems and their TDS reduction performance, and a system can carry that certification without a separately tested and listed fluoride claim. Before buying, check the product’s own spec sheet, or its listing in the NSF or WQA product database, for the word “fluoride” specifically, not just a general certification number.

It’s also worth testing your own water first. Fluoride levels vary by municipality and are naturally higher in some well water, and community water fluoridation policy differs city to city; the EPA opened an expedited federal health review of fluoride in drinking water in 2025, still ongoing as of this writing, which is part of why more households are checking their own tap levels rather than assuming a national default. A simple at-home test kit or a lab test through your water utility tells you what you’re actually starting from, which matters more than any brand’s marketing copy.

Which Option Fits Your Situation

• Renting, or not ready to commit to plumbing: a specialty pitcher from Epic Water Filters or Clearly Filtered gets you fluoride reduction with zero installation.
• Want fluoride handled alongside PFAS, lead, and general TDS in one system: an under-sink RO system, such as Viomi’s V6 PRO or Viomi V8 PRO, or a comparable model from APEC, iSpring, or Waterdrop, addresses all of it through one installed RO system instead of stacking separate filters.
• Want RO-level filtration plus mineral remineralization and a touchscreen display: Viomi’s M1 adds remineralization and a live TDS/filter-life display on top of the same RO filtration described above.
• Already own a Berkey: the PF-2 add-on set is the more practical upgrade over replacing the whole system.
• Need fluoride reduction at every tap in the house, not just the kitchen: a whole-house system like SoftPro’s is one of the few options built for that scale.

FAQ

Does Brita remove fluoride? No. Brita’s standard activated carbon filters are certified for chlorine, taste, and odor, not fluoride, and independent testing shows most fluoride passes through unchanged.

Does reverse osmosis remove all fluoride? Not literally all of it, but a well-functioning RO system typically reduces fluoride by roughly 90 to 98 percent, depending on the membrane, water pressure, and how much fluoride was in the source water.

Does boiling water remove fluoride? No, and it can make the concentration slightly higher. Boiling evaporates pure water molecules while fluoride stays behind, so a boiled glass can end up with a higher fluoride reading than before boiling, not a lower one.

Is my city’s water still fluoridated in 2026? It depends on where you live. Some municipalities have ended community water fluoridation in recent years, while others continue it, and the EPA is currently running a federal health review of fluoride that had not changed the existing legal drinking water limit as of this writing. Your local water utility’s annual water quality report is the most reliable source for your specific address.

Do I need to worry about losing beneficial minerals along with fluoride? RO and distillation remove most dissolved minerals along with fluoride, which is why several RO systems, including Viomi’s M1, add a remineralization stage afterward. If you’re using a specialty fluoride pitcher, check whether it does the same, since not all of them do.

How do I know a filter’s fluoride claim is real and not just marketing? Look for a specific fluoride reduction number tied to an NSF, WQA, or IAPMO certification, or an independent third-party lab test the brand cites by name, such as SGS, one of the world’s leading testing, inspection, and certification bodies. A general phrase like “removes contaminants” without fluoride named specifically is not the same as a tested claim.

The Bottom Line

If fluoride is the contaminant you’re trying to solve for, the filter type matters more than the brand name on the box. Reverse osmosis, distillation, and activated alumina or specialty ion-exchange media are the methods with a real track record; standard carbon, the kind in most pitchers and fridge filters, is not. Viomi’s M1 and Viomi V6 PRO / Viomi V8 PRO fall into the RO category, with fluoride listed on their official spec sheets among the contaminants their membranes are built to reduce, alongside PFAS, lead, and general TDS, and with the Viomi M1’s SGS-verified reduction rates above 99% for PFOS, PFOA, and lead, plus the Viomi V6 PRO / Viomi V8 PRO’s own SGS-verified fluoride reduction above 99% fresh (97.9 to 99.4% through the filter’s rated service life), backing up the rest of that claim. For anyone weighing fluoride against a broader list of concerns rather than fluoride alone, that combination of coverage in one continuous system is the practical case for RO over a single-purpose pitcher. Whichever brand you land on, the one habit worth keeping is checking the product’s actual certification listing for the word “fluoride,” rather than assuming any filter labeled “water purifier” is already handling it.
