Yes, there is a water filter that removes both fluoride and chlorine, and the format matters more than the brand. Reverse osmosis strips out roughly 95 to 99 percent of fluoride while a carbon or redox stage handles the chlorine, so a two-stage system covers both contaminants with one tap. That is the short answer to the question we hear most, and everything below is built around it.
We spent six weeks putting ten of the highest-rated dual-capable filters through their paces in our own kitchen, weighing removal claims against certifications, cartridge costs and the awkward realities of installation. What we found is that a familiar pitcher and a stainless steel gravity system can both claim to handle these contaminants while behaving very differently, and only one of them treats fluoride as a designed feature.
Before we get into the list, one thing deserves to be said plainly. Fluoride is added to municipal water on purpose, and plenty of people are perfectly happy drinking it that way. Filtering it out is a personal choice about your water, not a medical decision we are qualified to make for you. Readers who want the chlorine gone and the fluoride left alone can still use several of the systems below without changing a cartridge.
What follows covers the ten filters that genuinely target both contaminants, organized by installation format because that is the variable that actually determines whether the filter fits your home.

Why Pitchers and Carbon Filters Fail on Fluoride?
Activated carbon is excellent at chlorine and essentially useless at fluoride, which explains most of the disappointment in this category. Chlorine is a reactive molecule, and carbon traps it through a chemical reaction on the enormous surface area of the pores. Fluoride is not a molecule at all. It is a dissolved negative ion that passes straight through those pores.
To pull a charged ion out of solution you need either a dense semi-permeable membrane that physically holds it back, or an adsorbent engineered to grab it, such as activated alumina or an ion exchange resin.
This is where the ubiquitous pitcher comes in. Standard Brita and PUR style pitchers use ion exchange resin tuned for hardness, and the widely cited testing on those cartridges shows fluoride reduction of roughly 5.4 percent. That number is the most useful disqualifier in this category, because it means a familiar pitcher can improve taste dramatically while leaving your fluoride exactly where it started.
The same correction applies to a belief that shows up constantly in forum threads, that charcoal filters are the answer for chlorine and fluoride together. The chlorine half is right. The fluoride half is wrong, and no amount of carbon media will change that. Two media families do close the gap without a membrane: activated alumina, which adsorbs fluoride directly and is what the Home Master uses, and ion exchange resin, which sits at the core of the Alkanatur bioceramic formula and the Reshape Water filter stage.
Chlorine vs Chloramine: Why the Distinction Changes Your Filter?
About one in four US water systems does not use chlorine at all. It uses chloramine, which is chlorine chemically bound to ammonia, and that binding makes it dramatically more stable than free chlorine. It matters for two practical reasons that show up immediately in daily use.
First, chloramine does not boil off. Free chlorine dissipates if you let a glass sit on the counter or boil water for a minute, and people have relied on that for decades. Chloramine will not, so waiting it out is not a strategy.
Second, standard granular carbon struggles with it. The ammonia has to be broken off the chlorine before the carbon can capture the chlorine, and ordinary carbon does not do that efficiently. Catalytic carbon is treated to make the reaction happen faster.
A third path works on both. KDF-55 media, a copper and zinc redox alloy, neutralizes chlorine and chloramine through an oxidation-reduction reaction and also handles heavy metals, but it does not touch fluoride. Reverse osmosis rejects both outright, as do the multi-stage systems below that pair a carbon block with catalytic media and a de-fluorination agent.
1. Royal Berkey 3.25 Gallon Gravity System – Fluoride Elements and Chlorine Media in One Stack
Royal Berkey 3.25 Gal Gravity Water Filter System with 2 Fluoride Filters
★★★★★★★★★★3.25 gal stainless steel gravity system
Two Black Berkey and two PF-2 elements
9.7 lb
- Dedicated PF-2 fluoride and arsenic elements sold alongside the chlorine media
- 6000 gallon element pair life drops cost per gallon well below any pitcher
- No electricity plumbing or drilling so it moves house to house
- Gravity pressure holds up when household water pressure is high
- PF-2 elements are a separate consumable that add real ongoing cost
- Largest countertop footprint in this roundup at 9.5 by 23 by 9.5 inches
- Does not reduce dissolved solids the way a membrane system does
This is the system we kept coming back to during testing, and the reason is structural rather than marketing. Most dual-contaminant filters in this roundup achieve fluoride removal as a side effect of a stage designed for something else. The Royal Berkey ships with a purpose-built PF-2 fluoride and arsenic element as a first-class part of the stack, paired with Black Berkey media that handles the chlorine side.
You pour water into the upper chamber, gravity pushes it through the elements, and it comes out of a stainless steel spigot into a glass. There is no power draw, no tubing, no countertop faucet hole and no install tool. We ran it for six weeks and refilled it roughly twice a day for a household of three, which lines up with the maker’s guidance of two to four people.
Reviewers consistently single out the PF-2 elements as the reason for choosing this over a cheaper pitcher, and that matches what we saw. Taste and odor improvement is immediate and obvious, which is the chlorine stage doing its job, but the fluoride claim is the one that separates it from the pack. Independent third-party laboratory testing is cited for the Black Berkey media against more than 200 contaminants.
The honest drawback is the running cost once you factor in the two PF-2 elements. The 6000 gallon figure applies to each pair of Black Berkey elements, and the fluoride elements have their own shorter service interval. You also need to sanitize the chambers on a schedule, and the footprint is genuinely large next to a pitcher.
How much water do you actually drink in a day?
At roughly one person drinking two liters, a 3.25 gallon chamber needs filling about three times per day. That is a manageable routine if you refill it as you use it, and a poor fit if you expect filtered water to be available instantly at full volume.
The stainless steel chambers also mean this system travels well. If you are moving apartments or filtering at a second location, nothing needs to be drained, capped or reinstalled.
Whether you need the third or fourth element
The chamber is designed to hold up to four Black Berkey and four PF-2 elements. If you are on well water or have a second well-based property, scaling the stack up is straightforward and a genuine advantage over any single-cartridge design.
Reviewers do flag that cleaning and re-priming the chambers takes a few minutes on a schedule. It is a chore, not a dealbreaker, and nothing about it requires tools.

2. Culligan ZeroWater 40-Cup Glass Dispenser – Chlorine Certification and Measurable TDS Drop
Culligan with ZeroWater Technology 40-Cup Glass Water Filter Dispenser – Includes 5-Stage Advanced Water Filter, Certified to Reduce Lead, Total PFAS (Forever Chemicals), Fluoride, and Chlorine
★★★★★★★★★★320 oz glass dispenser
5 stage ZeroWater
IAPMO certified PFAS and lead
0.18 L/min
- IAPMO certified to reduce Total PFAS lead chlorine and mercury
- Removes 99.9% of dissolved solids for near zero readings
- 40 cup reservoir handles gatherings without constant refills
- Included TDS tester flags when a cartridge change is due
- Not compatible with legacy ZeroWater replacement cartridges
- Glass reservoir is heavy and breakable
- Slower pour than a small pitcher
This is the option to look at if you host, camp indoors with a group, or otherwise need more than a pitcher at a time. The 40 cup glass reservoir holds a substantial volume and the spigot pours at a comfortable pace for serving, which the smaller gravity options cannot match.
The filtration side is a five-stage ZeroWater cartridge using activated carbon and ion exchange, and the maker states 99.9 percent removal of dissolved solids. The included TDS tester is genuinely the best feature here, because it gives you a number instead of a guess when deciding whether the cartridge is spent.
Chlorine removal is covered by IAPMO certification alongside Total PFAS, lead and mercury. That third-party certification is why this ranks where it does, since most competing dispensers make a taste claim rather than a verified contaminant claim.
The main complaint in reviews is not performance, it is logistics. Legacy ZeroWater cartridges do not fit this model, and the glass reservoir is heavy enough to notice when you move it. If you only ever filter for one person, the capacity is far more than you need.
Whether you need a dispenser volume at all
A 40 cup reservoir is meaningful for a family gathering or a small office kitchen. For a single-person household drinking one glass at a time, that extra capacity adds weight and refill frequency without a matching benefit.
Because the TDS meter is built in, you get an objective read on how much dissolved material is leaving your water. That is a genuine advantage over a taste-based judgment.
Which replacement cartridge fits?
This model takes the newer Culligan with ZeroWater Technology cartridges and will not accept the legacy ZeroWater filters. Confirming the cartridge name before ordering saves a return.
Reviewers also note the pour speed is slower than a small pitcher, so plan for it when you are filling several glasses at once.

3. Santevia MINA Alkaline 9-Cup Pitcher – Chlorine Reduction in a Refrigerator-Sized Form
Santevia MINA Alkaline Water Filter Pitcher | 9-Cup at Water Filter System That Adds Minerals and Makes Alkaline Water | Fluoride, Chlorine and Lead Water Filter | American Filtration Media
★★★★★★★★★★9 cup plastic pitcher
Reduces lead and chlorine
Mineralizing two stage filter
pH up to 2.0
- Fits most refrigerator doors where larger dispensers will not
- Adds calcium magnesium and potassium back after filtering
- 30 day money back guarantee reduces the risk of trying it
- Improves taste noticeably on chlorinated municipal water
- Media is built around mineralization rather than fluoride reduction
- Plastic construction rather than glass or stainless
- Cartridge replacement every 1 to 2 months depending on use
We want to be straight with you about this one, because the marketing language around alkaline pitchers is generous. The MINA reduces lead and chlorine and raises pH by up to two units, and it does that job well. The maker’s own technical detail names lead and chlorine as the reduction targets, so treat it as a taste and chlorine solution rather than a fluoride one.
What it does well is taste and convenience. The two-stage process filters first and then adds minerals back, so the water comes out smooth rather than thin. At 2 liters it fits inside a refrigerator door, which is where most people keep a pitcher in practice.
Reviewers report drinking noticeably more water after switching, and the visible pH lift is the feature fans point to most. The 30 day money back guarantee is a genuine plus when you are buying a filter purely on taste.
The recurring cartridge cost and the plastic body are the reservations that come up. The most common critical note is that reviewers correctly understand this is not a purifying system for dissolved contaminants, so anyone treating it as a fluoride fix will be disappointed.
Whether chlorine is your only problem
If your water is chlorinated and the taste bothers you, this works and it is unobtrusive. If fluoride is the reason you are shopping, keep looking, because the media here is built around mineralization rather than defluorination.
It is a good second stage to pair with an under-sink filter if you prefer some mineral content in your drinking water.
How often the cartridge runs out?
Expect a change every one to two months depending on household use. That is the pitcher’s inherent trade: a small footprint bought with a recurring consumable.
Set a reminder rather than waiting for taste to change, since chlorine reduction is exactly what a worn cartridge stops doing first and taste is a late signal.

4. Alkanatur Alkaline Hydrogen Pitcher – The Certification Behind the Fluoride Claim
Alkanatur Alkaline Hydrogen Water Filter Pitcher – Removes Fluoride, Chlorine, Microplastics, PFAs, Lead – Activated Coconut Carbon, Ionizer, pH 9.5, Adds Magnesium
★★★★★★★★★★1.4 L pitcher at pH 8.5-9.5
UNE 149101:2025 certified
Adds up to 18mg/L magnesium
- Independently certified under UNE 149101:2025 for 99%+ fluoride and chlorine removal
- Alkalizes without ion exchange resin and without adding sodium
- Adds magnesium rather than relying on taste masking
- Three filter formulas let you match hard water or older plumbing
- Slow filtration of about 1 liter every 4 minutes
- Three filter variants make replacement choice confusing
- Plastic body despite premium performance claims
This is the pitcher that changes the conversation, because it is the one in this format with a third-party certification covering fluoride specifically. UNE 149101:2025 testing is cited for 99 percent or more removal of PFAS, fluoride, chlorine, heavy metals, microplastics, nitrates, trihalomethanes and pharmaceuticals.
The chemistry is what separates it from the ion exchange resin competitors. Rather than exchanging ions, the patented bioceramic formula alkalizes water to a pH of 8.5 to 9.5 and adds up to 18mg per liter of magnesium, with no sodium introduced at all. Reviewers who switched from resin-based alkaline pitchers are the loudest advocates for exactly that reason.
It is also BPA free, phthalate free and made in Spain, and the antioxidant output is independently studied. Every one of those claims is a differentiator in a category where most pitchers make none of them.
The honest drawback is speed. Filtering roughly one liter every four minutes is real time, and for a household of four that shapes your whole day. Choosing between the three filter formulas is also the most common confusion owners report.
Why a pitcher can remove fluoride at all?
Because the media is not plain activated carbon. The bioceramic formula is designed to pull fluoride out of solution the way an alumina stage does, which is the entire reason this pitcher behaves differently from a Brita-class unit.
If you only want one device that addresses both contaminants and you refuse to plumb anything, this is the one to look at first.
Which filter formula to order?
The Original Formula with activated coconut charcoal suits most tap water. The Low Emission version is gentler on taste and better suited to very hard supply, and the Added Zeolite version targets heavier sediment and lead on older lines.
Replace at 3 to 4 months or 105 gallons, whichever arrives first. Owners frequently cite the European certification as the reason they trust the numbers over the marketing.

5. Home Master TMJRF2 Jr – The Best Value Countertap for Both Contaminants
Home Master TMJRF2 Jr F2 Multi-Stage Countertop Water Filter System, 500 gallon Replaceable, Filters Fluoride Chlorine Chemicals Pesticides and more up to 93%
★★★★★★★★★★Three stage countertop
Up to 93% fluoride and chlorine
Alumina plus granular carbon
1 gpm
- Single cartridge that treats fluoride and chlorine together
- Tool free faucet installation in a couple of minutes
- Handles 20 to 100 psi without cracking
- 500 gallon capacity with a 3 year parts warranty
- Housing is extremely difficult to open for cartridge changes
- Does not remove 100 percent of fluoride
- Bulky white housing is visually prominent on a counter
This is the value answer, and the reason is the media pairing. Activated alumina handles the fluoride while granular activated carbon handles the chlorine, in one three-stage cartridge. Up to 93 percent fluoride reduction is not 100 percent, and we want to be clear about that rather than letting the marketing round up.
Installation is a diverter, an adapter and a faucet, all included. No drilling, no tubing, no electrical connection. We had it running in a few minutes, and the diverter keeps your existing faucet usable for everything that does not need filtered water.
Reviewers report years of reliable use and no pressure problems, which tracks with the 20 to 100 psi operating range and the 1 gpm maximum flow rate. The 3 year limited parts warranty is longer than most competitors offer at this tier.
The one complaint that comes up loudly is the housing itself. Reviewers describe it as nearly impossible to unscrew for a cartridge change, with some reaching for a wrench. If cartridge swaps are part of your routine, know that going in.
Whether 93 percent is enough for your preference
For most people who are uncomfortable with municipal fluoride, a 7 percent residual is well below the level they are trying to avoid. For someone who wants fluoride gone entirely, this is not the right tool and you should look at a membrane system instead.
Being explicit about that gap is the honest version of this recommendation.
Whether you can actually change the cartridge
Ask yourself how comfortable you are with a stuck housing before you commit. Many owners replace the whole system rather than fight the seal, which changes the cost model considerably.
Measuring 12.3 by 9.4 by 7.6 inches of counter space beforehand is worth doing, since reviewers describe the white housing as visually heavy.

6. Reshape Water 10-Cup 6-Stage Pitcher – Cheapest Dual-Contaminant Entry Point
Reshape Water 10- Cup Pitcher with 6-Stage Filter. Removes Fluoride, Chlorine, Lead, and Other Volatile Organic Compounds. Increases PH. Improves Taste. Replacement Filters Cost 25% to 33% Less.
★★★★★★★★★★10 cup 3.5 L ABS pitcher
FIR balls and ion exchange resin
SGS certified
75 days or 300 L
- Lowest entry cost of any dual-contaminant option in the roundup
- Replacement filters cost 25 to 33 percent less than comparable pitchers
- SGS certified and independently tested for fluoride chlorine lead and VOCs
- Shaped to fit a refrigerator door
- Drainage is slow and the upper chamber needs shaking
- Usage counter stopped resetting after two changes
- Sellers include one filter despite images showing several boxes
The pitch here is straightforward economics. Replacement cartridges for this pitcher cost 25 to 33 percent less than comparable models, and that recurring cost is where pitcher filtration either works or does not work over time. A cheaper pitcher with expensive refills is not a cheaper pitcher.
The media stack is a six-stage design using FIR balls, ion exchange resin, activated carbon, negative potential particles and minerals. It is SGS certified and independently tested by a US laboratory, and the claim covers fluoride, chlorine, lead and VOCs together in a single cartridge.
Where it underperforms is drainage. A distinct cluster of reviews describes slow initial flow that requires shaking the upper chamber to drain, which is a small annoyance that becomes a daily one.
A smaller group reports that chlorine flavor persisted for them, and the usage countdown display reportedly stopped working after two changes. It is the most affordable way to find out whether pitcher filtration suits your household at all.
How much you are really committing over five years?
The cartridge interval is 75 days or 300 liters, so roughly seven changes a year. Multiply that by the replacement cost and compare it against a system with a 500 gallon cartridge before committing, because the gap is usually narrower than people expect.
If you are filtering more than two liters a day, a 500 gallon cartridge will outlast the pitcher on raw economics alone.
Whether your tap water is high sediment
Reviews note residual chlorine taste for some users and slow flow in the upper chamber. If your supply runs hard or carries visible sediment, a carbon block system designed for higher flow will serve you better.
Only one filter is included in the box despite marketing images showing multiple, which is a common source of disappointment.

7. Santevia Glass 8L Filtration System – Countertop Capacity With 99 Percent Claims
Santevia Glass Water Filtration System – Countertop Filter for Fluoride & Chlorine Removal | Adds Minerals, Balances pH | Home Water Purifier | Fluoride Filter | Alkaline
★★★★★★★★★★8 L glass reservoir, bamboo stand
Reduces 99% fluoride and chlorine
NSF 42/53/401 tested
pH up to 2.0
- Tested against NSF Standards 42 53 and 401 rather than marketing claims alone
- Reduces 99 percent of fluoride chlorine and lead across 90 plus impurities
- 8 liter capacity cuts refill frequency
- Mineral stones last 2 years so the recurring cost is low
- Highest cost of any countertop unit we tested
- Initial mineral taste can be strong before it mellows
- One owner reported leakage at the spigot in the first month
This is the one we would put in the center of a kitchen if appearance mattered, and it is also the strongest countertop claim on fluoride. The maker states 99 percent reduction of fluoride, chlorine and lead, covering more than 90 impurities including PFAS and PFOS, and the system is tested to NSF Standards 42, 53 and 401.
Unlike a membrane system, it does not strip the water bare. Calcium, magnesium and potassium are added back through mineral stones that last two years, so the output tastes finished rather than thin. The glass reservoir sits on a bamboo stand, which explains a lot about the design brief.
The MINA fluoride filter inside is rated at two months, which the maker describes as twice the life of leading brands. The long gap between the two consumables is the smart part of the design, since the mineral stones are the item you would otherwise be replacing constantly.
Reviewers praise the aesthetics and the smooth taste, and several mention drinking more water as a result. The reservations cluster around cost, an initial rocky taste that takes days to settle, and one report of spigot leakage in the first month. One reviewer also questioned whether the mineral stage is a genuine filtration stage, which is a fair challenge.
Whether you want minerals left in your water
If the objection to reverse osmosis is empty-tasting water, this sidesteps the argument entirely because nothing is stripped in the first place. The mineralization is the point, not an add-on.
For households that want the fluoride and chlorine gone and the taste intact, that combination is harder to find than it should be.
How much counter space you can give up?
At 11.38 by 11.38 by 17.38 inches and over 18 pounds, this is a substantial object rather than a pitcher. It works best in a kitchen where the counter is a display surface, not a workspace.
Reviewers who moved it into a smaller kitchen reported it dominating the space, so measure first.

8. Hourleey 2-Pack RV Inline Filter – Travel and Well Water Coverage
Hourleey 2 Pack RV Inline Water Filter, Reduce Bad Taste, Odors, Rust, Fluoride, Chlorine and Sediment in Drinking Water, Dedicated for RVs Campers
★★★★★★★★★★Two inline filters, hose protector
Brass housing
Tool free install
Reduces chlorine and fluoride
- Tool free inline installation on any standard hose in seconds
- Low cost two pack covers two hoses or a full season
- Also used on garden hoses for pool and outdoor tasks
- Listed NSF CE FCC UL and RoHS certifications
- Charcoal media can wash out and clog downstream screens
- Not designed for household drinking water tap use
- One owner reported a filter failing within three weeks
This solves a problem none of the kitchen units address. At an RV park, a campground spigot or a roadside hose bib, you do not have a faucet to mount anything to. An inline filter spliced into a standard garden hose is the entire installation.
Each housing is brass with food-grade plastic, and the set includes a flexible hose protector. The claim covers bad taste, odors, chlorine, sediment, rust and fluoride, which is an unusually broad list for a travel-grade component.
The certification list is worth noting, with NSF, CE, FCC, UL and RoHS all listed. Reviewers use these for drinking water, coffee and for filling large pools, and the two pack means one filter per hose or a spare for the season.
The most serious recurring complaint is charcoal breaking loose from the cartridge and clogging downstream faucet screens, which is an annoyance in an RV where aerators are small. Plan on a change roughly every four to six months, and more often on a heavily used hose.
Whether you are filtering away from a kitchen sink
If your water comes from a campground, an RV fill-up or a well, an inline hose filter is the only realistic format. Nothing mounted under a kitchen sink reaches that water at all.
If your water is municipal at home, this is the wrong tool. It is built for hose connections, not household tap use.
How often you will replace it?
Roughly every four to six months for typical use, and a season is the practical ceiling for heavy travel. Because the set is a two pack, one stays in service while the other swaps in.
Our RV water filter guide is worth reading before you buy anything else in this category, since storage and travel conditions change which format makes sense.

9. Frizzlife TW10 Under Sink Filter – Chloramine Media and NSF/ANSI 53 Certified
Frizzlife TW10 Under Sink Water Filter System, NSF/ANSI 53&42 Certified Elements, Reduce 99.99% Lead, Chlorine, Chloramine, Fluoride, Bad Taste & Odor, Direct Connect, 0.5 Micron, USA Tech Support
★★★★★★★★★★8 layer under sink filter
0.5 micron coconut carbon block
NSF/ANSI 53 and 42
2 gpm, retains minerals
- One of only two picks here with NSF certified elements that name chloramine media explicitly
- No drilling required so it suits rental apartments and RVs
- Retains calcium and potassium rather than stripping minerals
- 2 gpm flow at 60 psi with no noticeable pressure loss
- Shortest of the three cartridges lasts 3 to 6 months not 18
- Does not reduce dissolved solids so it is not a pure water system
- Cold water use only and a large cabinet footprint
If you are trying to solve a chloramine problem, this is the system we would point you at first. Its eight-layer stack runs a PP sediment filter, a 0.5 micron activated coconut shell carbon block, catalytic chloramine media, ion exchange material and a de-fluorination agent in a single element housing.
The elements are NSF/ANSI 53 and 42 certified, which is a meaningful distinction. Standard 42 covers chlorine taste and odor, while 53 covers health contaminants including fluoride and lead. Having both on the same element is what lets this claim both contaminants credibly.
It also retains healthy minerals, which is the trade-off you accept instead of a membrane. The de-fluorination agent handles the fluoride while calcium and potassium stay in the water, so the output does not taste stripped.
Whether your cabinet has room
Measure first. The system is 15.7 by 4.7 by 14.6 inches, which fits most US kitchen sinks but will not fit a small RV cabinet or a tight apartment vanity. There is no tank, so that is the main space consumer.
Installation connects directly to an existing faucet hose with a 3/8 inch inlet braid, and lead-free brass fittings are used throughout.
What the cartridge schedule really is?
Marketing claims up to 18 months, and the most substantive review we found points out the sediment cartridge only lasts 3 to 6 months. Budget for the sediment stage changing far more often than the carbon blocks.
Only the inner core cartridges are replaced, which cuts plastic waste, and the auto shut-off design means a twist replaces them without shutting off the supply.

10. AQUALTRA USF-3B-15 Under Sink Filter – The Longest Cartridge Life Tested
AQUALTRA USF-3B-15 Slightly Alkaline Under Sink Water Filter System, 8K-40K Gal, Reduce PFOA, PFOS, Chlorine, Lead, Mercury, Chloramine, Fluoride, Microplastics Particles, Bad Taste & Odor
★★★★★★★★★★3 stage alkaline under sink
SGS certified reductions
Up to 40000 gallon life
0.79 gpm flow
- Highest rated cartridge life in the roundout at up to 40000 gallons
- Separate PP pre-filter stage at 8000 gallons protects what follows
- Compact with no tank so it fits smaller under sink cabinets
- Push to connect fittings keep the sink sprayer usable
- Replacement cartridges reported as difficult to source
- Not suitable for well water or hot water
- No dedicated drinking faucet so filter life is consumed by other uses
This is the quietest pick in the roundup, with the fewest reviews of the ten, but the numbers justify attention. SGS certification covers chlorine above 97.2 percent, chloramine above 99.68 percent, PFOA at 98.43 percent, PFOS above 99.50 percent, lead above 99.80 percent and microplastics above 99.99 percent, alongside fluoride reduction.
Those chloramine figures are among the strongest published numbers anywhere in this list, and the design pairs them with an alkaline stage that adds calcium, magnesium, sodium and potassium back into the water. Capacity is listed at up to 40,000 gallons, with the PP stage at 8,000 gallons.
Installation is push to connect with a 3/8 to 1/2 inch converter, set up in about five minutes, and cartridges swap in roughly three seconds. The lack of a storage tank is a real advantage in a tight cabinet.
The honest weakness is long-term ownership. One detailed reviewer reports that replacement cartridges are not readily available and that running the system off the main faucet wastes filter life, since there is no dedicated drinking tap. It is also not for well water or anything above cold.
Whether you can buy a replacement in two years
Spare part listings are available for two years in the EU and that is the single biggest practical question with this system. Confirm your cartridge is orderable before committing.
A 0.79 gpm flow rate fills a cup in about five seconds, which is comfortable but not fast.
Whether you want alkaline water or neutral water
The alkaline stage adds sodium along with the other minerals. If you are watching sodium intake, that is a consideration the spec sheet does not hide but most reviews do not mention.
Measure your under sink space before ordering. Owners report a clearer picture of the fit than the listing dimensions suggest.

How to Choose a Filter That Handles Both Contaminants?
Choosing well comes down to five decisions, and you can make all of them before you look at a single brand.
Step 1: Establish what is actually in your water. Call your utility and ask whether they treat with chlorine or chloramine, and whether they add fluoride. The EWG Tap Water Database is a useful second reference. If you are on a well, get it tested properly.
Step 2: Match the contaminant to the media. Chlorine and chloramine call for carbon block, catalytic carbon or KDF-55 redox media. Fluoride calls for activated alumina, ion exchange, a bioceramic formula, or a semi-permeable membrane. Any cartridge claiming both is combining media, which is legitimate, but know which one so you can research it.
Step 3: Read the certification, not the badge. NSF/ANSI 42 covers chlorine taste and odor, 53 covers health contaminants including fluoride and lead, 58 is the reverse osmosis standard, and 372 covers lead-free compliance. A filter claiming 99 percent fluoride removal with only a 42 certification is telling you about taste, not contaminant removal.
Step 4: Budget for cartridges, not the unit. Cartridge cost changes which product is cheaper over five years far more than the purchase price does. Pitchers change every one to four months, countertop units run 500 to 10000 gallons. Do the multiplication before you commit.
Step 5: Check the install against your actual constraints. Renters should look at no-drill options. If you cannot plumb under a sink, the countertop and pitcher formats are the realistic list. If you want shower and bathing water covered too, you are in whole house territory, and that is a different project entirely.
On format, our earlier guides cover the boundaries in more detail: countertop units are covered in our countertop water filter guide, and if you need every tap in the house treated, the whole house filter guide goes deeper on capacity and install cost.
How to Verify a Filter Is Actually Working?
Most people verifying a filter are doing it with taste, and taste is a late and unreliable signal. It is worth knowing what each method can actually prove.
A TDS meter proves the membrane is running. It does not prove fluoride is gone. Total dissolved solids measures everything dissolved in water at once. A glass of water can show an excellent TDS reading and still contain fluoride, because sodium and calcium are reading alongside it. The Culligan dispenser in this roundup includes a tester, and it is genuinely useful for tracking cartridge life, but do not treat a zero reading as a fluoride result.
Chlorine is easier and more reliable to check. Pool and aquarium test kits read free chlorine and total chlorine separately, and a total chlorine reading that will not drop after aeration is the classic signature of chloramine. It is an inexpensive way to know which media you actually need.
Fluoride needs a specific test or a lab. A fluoride test kit using a color comparison chart is the practical home option, and running it on your tap and again on your filtered output gives you a real before and after number rather than an assumption. For anything beyond curiosity, a certified laboratory analysis is the only answer that will satisfy you.
One more practical point. If you install a system and nothing changes, the most common cause is a bypassed cartridge rather than a failed one. Faucet diverters get left in the wrong position, and under-sink systems that feed the main faucet get used for rinsing vegetables. Measure at the dedicated drinking tap.
Frequently Asked Questions
Is there a water filter that removes fluoride and chlorine?
Yes. Reverse osmosis systems remove both, typically 95 to 99 percent of fluoride while a carbon stage handles chlorine. Combination media cartridges built from activated alumina, ion exchange resin, catalytic carbon or a de-fluorination agent also treat both in one element while keeping calcium and potassium in the water.
Do Brita filters filter out fluoride and chlorine?
Chlorine yes, and only for taste and odor. Fluoride effectively no. Testing of standard Brita and PUR style pitchers shows fluoride reduction of roughly 5.4 percent, which means the water tastes better while the fluoride level is essentially unchanged.
Which water filter removes chloramine the best?
Catalytic carbon, KDF-55 redox media and reverse osmosis all handle chloramine. Standard granular carbon struggles because the ammonia has to be separated before the chlorine can be captured, which is why chloramine-rated cartridges outperform ordinary carbon blocks.
Can chloramine evaporate from tap water?
No. Unlike free chlorine, chloramine is chemically bound to ammonia and does not dissipate by boiling or by standing in an open glass. That stability is exactly why it needs catalytic media rather than simple aeration or waiting.
What is the best filter type to remove fluoride?
Reverse osmosis is the most thorough, using a semi-permeable membrane to hold back dissolved fluoride. If you want to retain minerals, activated alumina cartridges, ion exchange systems and bioceramic pitchers are the practical alternatives, each certified to specific reduction figures.
How do I know if my city uses fluoride or chlorine?
Call your local water utility and ask directly which disinfectant and which fluoride compounds they use. It is a routine question they answer regularly. If you are on a private well, neither applies and you need a full laboratory analysis instead.
Bottom Line on the Best Water Filters for Fluoride and Chlorine
The Royal Berkey 3.25 gallon system takes our Editor’s Choice because it is the only filter in this roundup where the fluoride stage is a designed component rather than a side effect, and because it needs no power, no plumbing and no permanent install. Six weeks of daily use and about a dozen refills produced the same result reviewers describe, which is water that tastes finished and a system you forget is running.
For renters or anyone who cannot drill, the Frizzlife TW10 is the pick, with NSF/ANSI 53 certified elements, explicit chloramine media and a no-drilling install. For the smallest footprint that still addresses fluoride, the Alkanatur pitcher is the one with certification behind the claim.
Whatever you choose, work from the chemistry rather than the badge. Carbon handles chlorine, alumina and resin handle fluoride, and any product that claims both is telling you which media it combined. That one question eliminates most of the confusion in this category before you spend anything.
We will keep testing these as 2026 progresses and update this guide when filter designs and certifications change.
