Filters certified for lead — the 615, and the category with none

By Andrew Bates, FounderPublished 2026-09-10Updated 2026-09-11

NSF's listing held 615 distinct models with a lead reduction claim under NSF/ANSI 53 on 2026-09-10, from 63 companies, plus 127 more under NSF/ANSI 58. Almost half are refrigerator filters. No whole-house system holds the claim at all, and only four pitchers do.

The widest certified population here, and the empty category

Lead has more certified products behind it than any other health claim on this site. NSF’s listing on 2026-09-10:

	Lead, NSF/ANSI 53
Rows NSF returned	1,003
Distinct model designations	615
Companies	63

And one category is missing entirely.

No whole-house system holds the claim

The point-of-entry category does not appear in the lead claim set. Not few — none.

For contrast, the same database held 58 distinct point-of-entry models with a chlorine reduction claim under NSF/ANSI 42. Whole-house products exist and get certified; none of them is certified for lead.

That matches how lead reaches you. EPA states that where a home has a lead service line, “these pipes are typically the most significant source of lead in the water” — and both the service line and household plumbing sit downstream of where a point-of-entry unit is installed. A whole-house filter treats water before it passes the pipe that contributes the lead.

If a supplier offers you a whole-house system for lead, the question is which accredited body certified it and for which claim.

→ How to read an NSF listing, footnotes included

What NSF/ANSI 58 adds, and what it does not change

Everything above is the NSF/ANSI 53 lead claim. Reverse osmosis systems carry a separate lead claim under NSF/ANSI 58, and that search returns 145 rows resolving to 127 more distinct models from 35 companies.

Every one of those 127 is listed as plumbed-in to a separate tap. So the point-of-entry finding holds across both standards: no whole-house product holds a lead reduction claim under NSF/ANSI 53 or NSF/ANSI 58.

Those same 127 models also hold an NSF/ANSI 58 fluoride claim — the two sets are identical.

Where the certified products actually are

Distinct models holding the NSF/ANSI 53 lead claim, by category:

Category	Models
Refrigerator filter, aftermarket	181
Plumbed-in	161
Plumbed-in to separate tap	113
Refrigerator filter, integrated	101
Faucet mount	29
Counter-top connected to sink faucet	24
Pour-through (pitcher)	4
Commercial modular	2
Point-of-entry (whole-house)	0

Two numbers deserve attention.

Refrigerator filters are 282 of 615 — 181 aftermarket plus 101 integrated, just under half the certified population. For many households the lead-certified filter in the kitchen is already installed.

Four pitchers. Pour-through is the format most households reach for after a lead scare, and four distinct models held the claim on the capture date, from three companies. That is not a reason to avoid pitchers; it is a reason to check the specific model rather than assuming the category.

The decision framework

1. Establish that you have lead to treat

Lead is picked up in your plumbing, so a compliant utility report is not a measurement of your tap. A first-draw test is.

If you have a lead service line, EPA states it is typically the most significant source, and the Lead and Copper Rule Improvements require the vast majority of systems to replace such lines within ten years.

→ Lead: the action level, and what your utility owes you

2. Treat the tap you drink from

The certified population says this as clearly as EPA’s exposure-route framing does: every lead-certified model in the listing is point-of-use.

3. Choose the format from where the claim actually sits

If you have a fridge dispenser, that category holds 282 of the 615 models and you may already be covered — look your existing cartridge up before buying anything.

If you want a fitted unit, plumbed-in and plumbed-in to separate tap hold 274 models between them.

If you want a faucet mount, 29 models hold the claim, all listed under a single company in this set.

If you want a pitcher, four models hold it. Check the model number against the listing rather than the shelf label.

4. Read the marking you are being shown

Two lead-related markings point in opposite directions. NSF/ANSI/CAN 372 certification concerns the lead content of the product itself, for “lead free” plumbing under several state laws. Lead reduction is a separate claim.

A listing can also carry the footnote “conforms to the material requirements only”, which places a product under a standard with no reduction claim at all.

Applying the framework: who holds the claim

The certified population by company. Not a ranking and no recommendation — the set any recommendation would have to come from.

Company	Models	Categories
Qingdao Ecopure Filter Co., Ltd.	175	Refrigerator filter, aftermarket 175
Solventum Purification Inc.	43	Plumbed-in 39, separate tap 2, fridge 2
Everpure LLC	33	Plumbed-in 29, commercial 2, separate tap 2
Pentair Residential Filtration	32	Separate tap 19, plumbed-in 13
Kaz USA (Helen of Troy)	29	Faucet mount 29
Whirlpool Corporation	27	Refrigerator filter, integrated 26, plumbed-in 1
Access Business Group (Amway)	26	Separate tap 13, counter-top 13
Water Channel Partners	21	Separate tap 14, plumbed-in 7
Brio Water Technology	14	Separate tap 8, plumbed-in 6
Doulton Water Filters	14	Plumbed-in to separate tap 14

The remaining 53 companies hold fewer than 14 models each.

Notes tied back to the criteria

Qingdao Ecopure’s 175 are all aftermarket refrigerator filters. Aftermarket fridge filters are listed as many part numbers covering different fridge fitments, so a high model count reflects fitment coverage rather than 175 different filtration products.
Kaz USA holds all 29 faucet mounts in this set. If a faucet mount is the format you want, the certified choice in NSF’s listing is narrow by company even though 29 models is not a small number.
The four pour-through models are listed under The Brita Products Company (two), 4Patriots (one) and Electrophor (one).
Doulton’s 14 are all plumbed-in to separate tap, a reminder that a brand known for one format may hold claims only in that format.

The decision path

Your situation	What decides it	Where that lands you
Lead service line, replacement pending	Ingestion route, interval to cover	Point-of-use; 615 models to choose from
Have a fridge dispenser	Largest certified category	Look up your existing cartridge first
Want a pitcher	Only four models hold the claim	Check the model, not the shelf
Offered a whole-house lead filter	No certified example here	Ask which body and which claim
Shown a “lead free” marking	It is about the product’s own lead	Ask for the reduction claim instead
No test result yet	Nothing can be sized	First-draw test of your own tap

Choose a refrigerator filter if

You already have a dispenser and the cartridge model lists the claim. That category holds 282 of the 615 models, and confirming costs nothing.

Choose a plumbed-in or under-sink system if

You want the widest fitted choice, at 161 plumbed-in and 113 to a separate tap.
You are willing to install, or to pay someone to.

Choose a faucet mount or pitcher if

You want a lower-cost route to a certified claim and can verify the exact model — 29 faucet mounts and four pitchers hold it.

Choose to test first if

You have no result. Every choice above assumes lead is present, and a compliant utility report does not measure your tap.

Mistakes that cost the most money

Buying whole-house for lead. No point-of-entry product holds the claim in NSF’s listing, and the lead is picked up downstream of where such a unit sits.

Assuming any pitcher covers it. Four pour-through models held the claim on the capture date. The category is not the claim.

Reading NSF/ANSI 372 as lead removal. It describes the lead content of the product. The word “lead” appears in both and they point in opposite directions.

Replacing a fridge cartridge without checking. The one already fitted may hold the claim, and the aftermarket equivalent may not.

Treating certification as a health guarantee. EPA sets the goal for lead at zero, stating there is no safe level of exposure. A claim is a tested reduction, not an elimination of risk.

Forgetting the replacement schedule. EPA states carbon filters have a specified shelf life and should be replaced on schedule. An exhausted cartridge is a bypass.

Three situations, and what changes

Your utility has told you there is a lead service line. EPA states that pipe is typically the most significant source, and replacement is required of most systems within ten years. Filtration covers the interval, at the drinking tap, and the certified population is wide enough that format is a convenience choice.

You already run a fridge filter and a lead scare has just happened locally. Look the cartridge up before buying anything. Refrigerator filters are the category holding 282 of the 615 certified models, so you may already be covered.

A contractor has quoted you for a whole-house lead system. No such product holds the claim in NSF’s listing. Ask which accredited body certified theirs and for which claim, and compare the quote against a point-of-use unit treating the water you actually drink.

The objections worth answering

“Whole-house must be better, it treats everything.” It treats more water, upstream of the pipe that contributes the lead. The certified population reflects that: 58 point-of-entry models hold a chlorine claim and none holds a lead claim.

“Only four pitchers? That cannot be right.” It is NSF’s listing on one date for one claim, counting distinct model designations. Other certifiers publish separately and this page does not cover them.

“My filter says it reduces lead by 99 percent.” That names a figure and no standard. The listing names the claim, per model, and is the document such marketing is summarising.

“These figures will move.” They will. NSF dates its listings and asks readers to confirm status at source, which is why the capture date sits beside every figure here.

Who this is for

Households with a lead result, a lead service line, or a lead notice from their utility, choosing where and what to fit.

It is not a recommendation and names no pick. It is the certified population and the shape of it.

What to settle first

Is my model in the listing, and is the claim lead reduction rather than lead content?

Two checks. Between them they separate a certified lead filter from a product that merely has the word on the box.

→ Lead: the action level, and what your utility owes you → How to read an NSF listing, footnotes included → Which claims exist at all, and how populated each is → What a whole-house filter is certified to do, since it is not lead → Get the number first: testing city water for lead → Filter maintenance, and why an unlisted cartridge breaks the chain → Where the 615 lead models sit by product form → “Filter First”: which claim actually carries the lead performance

The bottom line

Treat the tap you drink from, because that is where the certified products are: no whole-house system holds a lead claim in NSF's listing, against 58 holding a chlorine claim. The population is wide — 615 distinct models from 63 companies — but concentrated in formats people overlook, with 282 of them refrigerator filters and only four pour-through pitchers. Verify the claim on the exact model rather than the brand, and remember EPA sets the health goal for lead at zero, so a certified filter reduces exposure rather than removing a risk entirely.

Who this is not for

This is NSF's listing on 2026-09-10 and nothing else. WQA and IAPMO certify to the same NSF/ANSI standards and publish separate listings, so a category showing zero here may hold certified products elsewhere. It is not a ranking, names no recommendation, and says nothing about how well any model performs a claim it holds. It also cannot tell you whether you have lead — that needs a first-draw test of your own tap.

Questions

How many water filters are certified for lead?

NSF's listing search returned 1,003 rows for lead reduction under NSF/ANSI 53 on 2026-09-10, resolving to 615 distinct model designations from 63 companies. Those are NSF listings only; other accredited bodies publish their own.

Is there a whole-house filter certified for lead?

None appeared in NSF's listing on 2026-09-10. The point-of-entry category does not appear in the lead claim set at all, against 58 point-of-entry models holding a chlorine reduction claim. Ask any supplier offering one which body certified it and for which claim.

Do water pitchers remove lead?

Four distinct pour-through models held a lead reduction claim on 2026-09-10, from three companies. Pitchers are a common purchase after a lead scare and a small part of the certified population, so the specific model matters more here than in any other format.

Do refrigerator filters remove lead?

Many are certified for it. Refrigerator filters account for 282 of the 615 distinct models holding a lead claim — 181 aftermarket and 101 integrated. No other category in the listing holds as many.

Where should I install a lead filter?

At the tap you drink from. Lead is an ingestion concern usually picked up in the service line or household plumbing, downstream of where a whole-house unit sits, and no point-of-entry product holds a lead claim in NSF's listing.

Does a certified filter make lead safe?

EPA sets the Maximum Contaminant Level Goal for lead at zero, stating there is no safe level of exposure to lead. A certified filter reduces exposure against a tested protocol; it does not convert a health goal of zero into a guarantee.

Does a lead-free marking mean the product removes lead?

No, and they point in opposite directions. NSF's marking for NSF/ANSI/CAN 372 covers the lead content of the product itself for "lead free" plumbing. Lead reduction is a separate claim under NSF/ANSI 53 or 58.

Should I filter if my utility is replacing my lead service line?

EPA's Lead and Copper Rule Improvements require the vast majority of systems to replace lead service lines within ten years, and state that where a home has one it is typically the most significant source of lead in the water. Filtration covers the interval.

Limits: Two standards searched on one date in one certifier’s listing. It does not establish that whole-house lead treatment is impossible, and the two sets are not checked here for overlapping models.
NSF — NSF/ANSI 42, 53 and 401: Filtration Systems Standards (page dated 2025-12-16)
NSF/ANSI 53 offers over 50 contaminant reduction claims, including lead, Cryptosporidium, VOCs and chromium. (captured 2026-09-09)
NSF — NSF/ANSI 42, 53 and 401: Filtration Systems Standards (page dated 2025-12-16)
Under NSF/ANSI 42 and NSF/ANSI 53, certification claims vary by product; certification to the standard does not mean a product carries every claim available under it. (captured 2026-09-09)
Limits: NSF does not print 'claims vary by product' under NSF/ANSI 401. See certification-nsf-0008 for the 401 position, which rests on weaker source language.
NSF — NSF/ANSI 58: Reverse Osmosis Drinking Water Treatment Systems (page dated 2025-12-18)
Under NSF/ANSI 58, TDS reduction is the only required claim. Every other claim, including arsenic, nitrate/nitrite, lead and cyst reduction, is optional. (captured 2026-09-10)
Limits: This is the sharpest form of "claims vary by product": a system certified to NSF/ANSI 58 is verified for TDS reduction and nothing else unless the individual claim is listed for that model.
NSF Official Listings — Drinking Water Treatment Units (listings current as of Thursday, September 10, 2026, 12:15 a.m. Eastern Time)
NSF Official Listings mark some entries "Conforms to the material requirements only", meaning the product appears under a standard without any contaminant reduction performance claim having been certified. (captured 2026-09-10)
Limits: The footnote states what was evaluated, not what the product does. It does not say the product performs badly, only that performance was not the basis of this listing. A separate listing for the same model can carry performance claims.

Limits: A statement about how much lead the product contains, not about how much lead it removes from water. Lead reduction is a separate claim under NSF/ANSI 53 or 58.
EPA — Basic Information about Lead in Drinking Water
EPA has set the Maximum Contaminant Level Goal for lead in drinking water at zero, because the best available science shows there is no safe level of exposure to lead. (captured 2026-09-10)
Limits: The MCLG is a non-enforceable health goal, not a limit a utility must meet. The enforceable trigger is the action level, which is a separate and higher number.
EPA — Basic Information about Lead in Drinking Water
EPA states that where a home has a lead service line connecting it to the water main, that pipe is typically the most significant source of lead in the water, and lead pipes are more likely in older cities and homes built before 1986. (captured 2026-09-10)
Limits: Homes without a lead service line can still have lead from brass or chrome-plated brass faucets and from lead solder, which EPA names as the most common problem in those homes.
EPA — Fact Sheet: EPA’s Lead and Copper Rule Improvements (October 2024)
EPA’s Lead and Copper Rule Improvements lower the lead action level from 15 micrograms per litre to 10 micrograms per litre. (captured 2026-09-10)
Limits: The action level is a trigger for utility action, not a health-based safe level — EPA sets the health goal for lead at zero. Exceeding it obliges the system to act; it does not by itself mean an individual tap is above or below it.
EPA — Fact Sheet: EPA’s Lead and Copper Rule Improvements (October 2024)
The Lead and Copper Rule Improvements require the vast majority of water systems to replace lead service lines within 10 years, and EPA states up to 9 million homes and businesses are still connected through legacy lead pipes. (captured 2026-09-10)
Limits: EPA notes that a limited number of systems in limited circumstances receive additional time. The requirement is on the utility for the service line, and does not cover lead in a household’s own internal plumbing.
EPA Office of Water — Home Water Treatment Facts / Filtration Facts (published November 2005)
EPA states that for most contaminants a point-of-use device treats only the water consumed, but that contaminants such as radon, disinfection byproducts and some organic chemicals easily turn into gases and may pose a risk when inhaled, such as when showering, which a point-of-entry device can reduce. (captured 2026-09-10)
Limits: States when whole-house treatment is warranted by exposure route. It does not establish that any particular home has volatile contaminants, which requires a test.
EPA Office of Water — Home Water Treatment Facts / Filtration Facts (published November 2005)
EPA states that an activated carbon filter by itself is not designed to remove all disease-causing organisms, and that carbon filters have a specified shelf life and should be replaced regularly per the manufacturer instructions. (captured 2026-09-10)
Limits: Concerns activated carbon as a class. Some carbon blocks carry certified cyst reduction claims, which is a model-specific capability rather than a property of carbon.
