Fluoride water filters: every NSF/ANSI 53 and 58 listing that names fluoride
A fluoride water filter should carry a certifier listing that names fluoride. Our database has 13 filters with one: 12 reverse osmosis systems listed under NSF/ANSI 58 and 1 pitcher under NSF/ANSI 53. Prices run from $34.99 for the ZeroWater 10 Cup Pitcher by Culligan to $1,099 for the Coway All-In-One Under Sink RO (P-160AL) (checked Oct 15, 2026). None of the shower, whole-house or well filters we track holds a fluoride listing. EPA's enforceable limit for fluoride in public water is 4.0 mg/L, and where utilities add it, the U.S. Public Health Service recommends 0.7 mg/L. The contaminants or other substances removed or reduced by this water treatment device are not necessarily in your water.

Who certified each filter
NSF/ANSI 53 and 58 are the same test whichever accredited certifier runs it. Here IAPMO R&T certified 6 filters, NSF 2 and WQA 5. We link one record per filter, the one that names fluoride. Of the 13, 13 are also listed for lead and 9 for PFAS. Every listing in our database, by substance, is in NSF certified water filters.

A 53 or 58 listing is not a fluoride listing
Waterdrop X12 Reverse Osmosis System, Waterdrop K19-SFK Countertop RO and Waterdrop M6SL Mineral Countertop RO hold IAPMO R&T listings to NSF/ANSI 58 for dissolved solids only, and the Express Water RO5DX 5-Stage Reverse Osmosis System an NSF listing for the same. The Bluevua ROPOT-Lite and Bluevua ROPOT-Travel hold WQA listings to the same standard that don't name fluoride. Their brands say they reduce it. WQA lists the Coway Under Sink RO (P-09CL), Coway Prime Countertop RO (P-6320L) and Coway Modern Countertop RO (P-300L) under NSF/ANSI 58 for lead and arsenic, not fluoride, and Coway's product pages for them don't mention fluoride. IAPMO R&T lists the A. O. Smith AOS-DFRO800 Tankless Reverse Osmosis under NSF/ANSI 58 for dissolved solids only and the APEC Water ROTL-A1000 Tankless Reverse Osmosis for dissolved solids, PFOA and PFOS; neither brand claims fluoride for them. In all, 28 filters in our database claim fluoride with no listing that names it: Clearly Filtered 3-Stage Under the Sink System, Waterdrop X12 Reverse Osmosis System, Clearly Filtered Water Pitcher, Epic Water Filters Pure XP Water Filter Pitcher, Waterdrop K19-SFK Countertop RO, Epic Water Filters Pure XP Dispenser, Bluevua ROPOT-Lite, Bluevua ROPOT-Travel, Waterdrop M6SL Mineral Countertop RO, SimPure Y7P-BW Countertop RO, iSpring RCD100 Countertop RO with Hot Water, APEC Water RO-CTOP-C Portable Countertop RO, Waterdrop King Tank 2.25-Gallon, Alexapure Pro, Waterdrop RV Inline Water Filter (WD-RVS), Clearly Filtered Stainless Steel Filtered Water Bottle, 20 oz, Express Water RO5DX 5-Stage Reverse Osmosis System, Express Water Model 6 ROT600MBN Tankless Reverse Osmosis, SimPure T1-400ALK Tankless RO with Remineralization, ProOne Big+ 3-Gallon, Santevia Gravity Water System, Santevia MINA Pitcher, Santevia Glass Water System, Frizzlife PD600-TAM3 Tankless Reverse Osmosis, Frizzlife MD40 Electric Countertop Filter Dispenser, Brio G10-U ROSL500 Tankless Reverse Osmosis System, Brio G20-U ROSL700 Tankless Reverse Osmosis System and Clearly Filtered Universal Inline Fridge Filter. Add-on fluoride cartridges aren't listed either: BOROUX's own report tested its fluoride filter at 0.7 ppm, and says NSF/ANSI 53 tests at 8 ppm.
Questions people ask
Can a water filter reduce fluoride?
Some can, and a certifier listing is how you check. Our database has 13 filters listed for fluoride, 12 of them reverse osmosis systems. Outside reverse osmosis, one pitcher holds a listing. CDC notes that some filters reduce fluoride, which it says prevents cavities, so check whether your utility adds it before you filter it. The contaminants or other substances removed or reduced by this water treatment device are not necessarily in your water.
Does reverse osmosis reduce fluoride?
It can, and the listing tells you which systems were tested for it. AquaTru Classic Countertop RO, AquaTru Carafe Countertop RO, AquaTru Under Sink Reverse Osmosis, Waterdrop G3P800 Reverse Osmosis System, Aquasana SmartFlow Reverse Osmosis, Pentair FreshPoint GRO-575 5-Stage Reverse Osmosis, Pentair OMNIFilter RO2050 4-Stage Reverse Osmosis, Coway All-In-One Under Sink RO (P-160AL), Kohler Aquifer RO (K-22155), Brondell Circle RC100 Reverse Osmosis, Brondell Capella RC250 Reverse Osmosis and APEC Water RO-90 Ultimate 5-Stage Reverse Osmosis are listed for fluoride under NSF/ANSI 58. Aquasana's data sheet for the SmartFlow RO shows a 90% average fluoride reduction, 85% at minimum. Not every 58 listing names fluoride: Waterdrop X12 Reverse Osmosis System, Waterdrop K19-SFK Countertop RO, Bluevua ROPOT-Lite, Bluevua ROPOT-Travel, Waterdrop M6SL Mineral Countertop RO, APEC Water ROTL-A1000 Tankless Reverse Osmosis, Coway Under Sink RO (P-09CL), Coway Prime Countertop RO (P-6320L), Coway Modern Countertop RO (P-300L), Express Water RO5DX 5-Stage Reverse Osmosis System and A. O. Smith AOS-DFRO800 Tankless Reverse Osmosis are listed for other contaminants.
Is there a water filter pitcher that reduces fluoride?
One in our database: the ZeroWater 10 Cup Pitcher by Culligan ($34.99), listed by IAPMO R&T to NSF/ANSI 53 for fluoride, lead and PFAS. The ZeroWater 10 Cup Pitcher looks the same but its listing doesn't name fluoride. Clearly Filtered Water Pitcher, Epic Water Filters Pure XP Water Filter Pitcher and Santevia MINA Pitcher claim fluoride reduction with no listing that names it. Prices checked Oct 15, 2026.
Does Brita filter fluoride?
None of the 5 Brita pitchers, bottles and faucet filters we track has a listing that names fluoride. NSF does list two Brita-branded reverse osmosis systems for fluoride under NSF/ANSI 58, the Brita Total360 BRDROS and the Brita PRO BPLRO-35. Other companies hold those listings, and we don't track the systems.
Do shower filters reduce fluoride?
None of the 15 shower filters we track holds a fluoride listing, though brands sell "fluoride shower filters." Shower filters are certified to NSF/ANSI 177, which covers free available chlorine reduction only. EPA's fluoride limits apply to drinking water. For chlorine in the shower, see our shower filter picks.
Do gravity water filters reduce fluoride?
None of the 18 gravity filters we track holds a fluoride listing. The Alexapure Pro claims fluoride for its main filter on the strength of the brand's own lab report, covered in my Alexapure Pro review, and the Waterdrop King Tank 2.25-Gallon ships with fluoride filters rated only by Waterdrop. The Santevia Gravity Water System also claims fluoride with no listing. Without plumbing, the listed options are the ZeroWater 10 Cup Pitcher by Culligan pitcher and countertop reverse osmosis from $375.
Is there a whole-house fluoride filter?
Not with a listing in our database. None of the 16 whole-house and well systems we track holds a fluoride listing. The 13 listed filters treat the water at one tap, the water you drink and cook with. For what whole-house systems are listed for, see whole-house water filters.
What are the federal limits for fluoride in drinking water?
EPA's enforceable limit is 4.0 mg/L. Above it, EPA lists bone disease, and children may get mottled teeth. Its secondary standard is 2.0 mg/L, for tooth discoloration, and utilities above it must notify customers. Where fluoride is added, the U.S. Public Health Service recommends 0.7 mg/L, which CDC says maximizes the benefits for teeth. In 2024 the National Toxicology Program concluded, with moderate confidence, that fluoride above 1.5 mg/L is associated with lower IQ in children, and found too little data to say whether 0.7 mg/L has that effect. EPA is reviewing fluoride on an expedited schedule and released its assessment protocol on August 3, 2026. The 4.0 mg/L limit hasn't changed (checked October 15, 2026).
