Berkey Water Filter Lawsuit Explained, Claims, Timeline, and Status

New Millennium Concepts, Ltd. (NMCL), the brand owner of Berkey water filters, is involved in multiple lawsuits — one filed by consumers against NMCL and two filed by Berkey entities against the U.S. Environmental Protection Agency. The consumer class action, filed in late 2022, alleges Berkey’s Black filters do not perform as advertised. The EPA lawsuits, filed in 2023 and 2024, challenge the agency’s decision to classify Berkey filters as regulated pesticide devices. As of early 2026, one EPA case is closed and one remains active.

Three Separate Cases — Read This First

Many readers searching “Berkey water filter lawsuit” are confused about which legal action they are reading about. There are three distinct cases. This article covers all three, explains what each one alleges, and clarifies which are still active.

Case Overview: The Three Berkey Lawsuits

Who is involved in the Berkey company structure?

Understanding these cases requires knowing who the players are. New Millennium Concepts, Ltd. (NMCL) is the brand owner and sole global distributor of Berkey water filter systems. Berkey International, LLC is a Puerto Rico-based company that manufactures the filters and supplies them to NMCL. The James B. Shepherd Trust (JBS Trust) owns the intellectual property behind Berkey products. These three entities are related but legally separate — which is why different lawsuits were filed by different plaintiffs.

Case 1: Consumer Class Action Against NMCL (Filed Late 2022) — Status Unclear

What this case alleges: A consumer class action was filed against NMCL in late 2022 alleging that Black Berkey purification elements do not perform as advertised. Plaintiffs claimed the filters were, in the words of the complaint, “nothing more than an empty can or plastic bottle” — meaning they did not effectively remove the contaminants that Berkey’s marketing materials promised. The lawsuit did not allege that consumers suffered physical harm from using the filters. It focused on false advertising and product misrepresentation claims.

Key background — the NSF/ANSI certification issue. A central element of the advertising claims concerns Berkey’s lack of NSF/ANSI certification. NSF International and the American National Standards Institute set widely recognized third-party standards for water filtration products. Most major filter brands carry NSF/ANSI certification, meaning their performance has been independently verified against standardized tests. Berkey has not sought this certification, relying instead on its own independent laboratory testing. Critics, including Wirecutter (The New York Times), tested Berkey filters and found results inconsistent with Berkey’s own performance claims. The company disputes these findings and attributes the lack of certification to cost rather than performance concerns.

NMCL’s response. NMCL denied all allegations and requested dismissal of the lawsuit. The company stated the case contained multiple factual and legal problems. As of early 2026, no public settlement website, settlement amount, or final court ruling in this consumer class action has been confirmed through available court records or verified reporting. The current status of this case should be verified through PACER (the federal court docketing system) for the most current updates.

What this means for consumers. If this case produces a settlement or judgment in favor of the plaintiff class, consumers who purchased Black Berkey purification elements during the covered period may ultimately be eligible for some form of compensation. No claim period is currently open, and no settlement administrator has been identified for this case.

Case 2: NMCL and JBS Trust v. EPA — Northern District of Texas (CLOSED)

Filed: August 9, 2023, in the U.S. District Court for the Northern District of Texas (Case No. 4:23-cv-00826-P)

What this case alleged. NMCL and the James B. Shepherd Trust filed this lawsuit challenging the EPA’s decision to issue Stop Sale, Use, or Removal Orders (SSUROs) against Berkey distributors and suppliers. The case asked the court to declare that the EPA had overstepped its authority under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) by classifying Berkey’s mechanical filtration elements as regulated pesticides.

Plain-language explanation of FIFRA and SSUROs. FIFRA is the federal law that regulates pesticides — substances intended to destroy, repel, or mitigate pests. An SSURO is a Stop Sale, Use, or Removal Order — essentially a government order preventing a company from selling or distributing a product until compliance is achieved. The EPA’s position was that Berkey’s Black filter elements, which contain silver as an antimicrobial component, qualified as pesticide devices under FIFRA because the silver is intended to destroy or repel microorganisms (pathogens in water). Berkey argued that the silver was used solely to protect the filter from degrading — not to make health claims about water purification — and that mechanical filtration products had never been regulated this way in Berkey’s 25+ year history.

What happened. U.S. District Judge Mark T. Pittman dismissed the case, ruling that NMCL and the JBS Trust lacked Article III standing — meaning the court found they were not directly harmed by SSUROs issued to dealers and suppliers rather than to NMCL itself. NMCL appealed to the Fifth Circuit Court of Appeals. The Fifth Circuit denied the request for an immediate temporary injunction in January 2024 and, after further briefing, ultimately did not reverse the standing ruling. NMCL petitioned the U.S. Supreme Court to take the case.

The Supreme Court declined. On December 16, 2024, the Supreme Court denied certiorari in this case — meaning it declined to hear the appeal. This denial ended Case 2 entirely. The dismissal for lack of standing stands. NMCL and the JBS Trust cannot revive this particular challenge.

Case 3: Berkey International v. EPA — District of Puerto Rico (ACTIVE)

Filed: March 6, 2024, in the U.S. District Court for the District of Puerto Rico (Case No. 3:24-cv-01106-CVR), before Judge Camille Velez-Rive

Why this case was filed separately. When Case 2 was dismissed because NMCL and the JBS Trust had not directly received SSUROs themselves, Berkey International — the Puerto Rico-based manufacturer that had directly received an SSURO — filed its own separate lawsuit. Unlike NMCL, Berkey International was the entity the EPA directly ordered to stop selling. This eliminated the standing problem that sank Case 2.

What this case alleges. Berkey International alleges the EPA violated FIFRA by classifying its mechanical water filters as pesticides without proper regulatory authority, without following the Administrative Procedure Act’s (APA) notice-and-comment rulemaking process, and without constitutional due process. The complaint argues that Black Berkey filter elements are mechanical filtration products — not pesticides — and that the EPA reversed 25 years of consistent regulatory treatment without legal justification.

Legal developments.

• April 2024: Judge Velez-Rive heard Berkey International’s request for a preliminary injunction. She did not rule immediately.
• 2024–2025: Both sides filed additional statements and arguments. Personnel changes at the EPA and Department of Justice — some named in court documents — occurred following the change in presidential administration in January 2025.
• August 5, 2025: NMCL representatives met with DOJ officials and the new Trump-appointed EPA director for Region 8. NMCL reported the meetings were “productive” and expressed hope for a favorable resolution in 2026.
• October 27, 2025: Oral argument in the related appeal (USCA Case Number 24-1917) was held before the First Circuit Court of Appeals in Puerto Rico. Audio of the 30-minute oral argument was made publicly available by Berkey’s dealer network.

Current status as of March 2026. Case 3 remains active. No final ruling has been issued by the District Court or the First Circuit on the active appeal. The court has not yet scheduled a trial date. Berkey International continues to be unable to manufacture Black Berkey filter elements under the existing SSURO while the litigation is pending. NMCL has stated publicly that it expects some form of resolution in 2026, though court proceedings do not operate on a guaranteed timeline.

The EPA’s Position

The EPA maintains that Berkey’s filter elements require registration as pesticide devices under FIFRA because they contain silver — a substance registered as a pesticide since 1954 — used for antimicrobial purposes. The agency’s position is that any product making claims about destroying or repelling microorganisms, or containing registered pesticide materials for that purpose, falls within its regulatory authority under FIFRA regardless of how the manufacturer characterizes the product. The EPA argues its enforcement actions protect consumers from products making unverified health and safety claims about pathogen removal.

What This Means for Current Berkey Owners

Black Berkey replacement filters are not currently being manufactured. Since May 2023, the SSURO has prevented Berkey International from producing Black Berkey purification elements. Pre-existing inventory sold out through 2024. The shortage is ongoing as of early 2026.

Counterfeit filters are a real risk. Both NMCL and authorized Berkey dealers have warned that Black Berkey replacement filters appearing on Amazon, Walmart, eBay, and third-party websites at this time are very likely counterfeit — produced by manufacturers using Berkey’s name without authorization. Counterfeit filters may not perform to any verified standard and could potentially introduce contaminants rather than remove them. NMCL recommends purchasing only from authorized dealers and verifying the source before buying any Berkey-branded filter elements.

Alternative authorized filters. While Black Berkey elements are unavailable, NMCL has introduced ceramic replacement filters (described as “ultra sterasyl ceramic filters”) as a compliant alternative for use in Berkey filter systems. Berkey systems themselves — the steel chambers — can still be purchased. Authorized dealers have also noted that Travel Berkey systems, which use different filter elements, remain more available.

Key Dates

Possible Outcomes (Educational Context)

In regulatory challenges like Case 3, a court could grant an injunction lifting the SSURO while the litigation continues, dismiss the case, or ultimately rule on the merits in favor of either party. If the court sides with Berkey International, the SSURO would be lifted and filter manufacturing could resume. If the court sides with the EPA, Berkey International would need to register its products as pesticide devices or cease manufacturing the elements in their current form. A negotiated resolution between Berkey and the Trump EPA — as the August 2025 meetings suggest is being explored — would not require a court ruling and could resolve the situation outside of litigation entirely.

In the consumer class action (Case 1), outcomes could include dismissal, a negotiated settlement, or a trial. If settled, consumers who purchased Black Berkey elements during the covered period might be eligible to submit claims. None of these outcomes can be predicted.

What This Means for the Water Filtration Industry

The Berkey EPA dispute has drawn attention from regulatory lawyers, water filtration manufacturers, and consumer advocates because its outcome could set a precedent for how FIFRA applies to other water filtration products that use silver or similar antimicrobial materials. Dozens of other water filter brands use similar materials. If EPA’s classification of Berkey’s products as pesticides is upheld, other manufacturers could face the same regulatory requirements — potentially disrupting a much wider market segment.

The consumer class action, if it proceeds, may also prompt other gravity-fed filter manufacturers to pursue NSF/ANSI certification proactively to reduce exposure to similar advertising claims. As of 2026, no comparable false advertising class actions against other major water filtration brands have been reported in public court records.

Frequently Asked Questions

Has the Berkey water filter lawsuit been decided? 

There are three separate cases. The consumer class action (filed 2022) has no confirmed final ruling publicly available. The NMCL/JBS Trust v. EPA case (filed 2023) is fully closed — the Supreme Court declined to hear the appeal in December 2024. The Berkey International v. EPA case (filed March 2024, Puerto Rico) is still active as of early 2026, with oral argument heard in October 2025.

What does the consumer class action allege? 

The 2022 consumer class action alleges that Black Berkey purification elements do not perform as Berkey’s marketing materials claim, amounting to false advertising. Plaintiffs did not allege physical harm — only that the product did not deliver the filtration performance advertised. NMCL denied all allegations and requested dismissal.

Why did the EPA classify Berkey filters as pesticides? 

The EPA determined that Berkey’s Black filter elements contain silver used as an antimicrobial agent — meaning they are designed to destroy or repel microorganisms — which falls within FIFRA’s definition of a pesticide device. Products in that category require EPA registration and labeling. Berkey disputes this classification, arguing the silver protects the filter from degrading rather than making health claims about water treatment.

What is Berkey’s response to the EPA’s actions? 

Berkey International and NMCL filed separate lawsuits arguing the EPA exceeded its legal authority, failed to follow proper rulemaking procedures under the Administrative Procedure Act, and treated Berkey differently from other water filtration manufacturers that use similar materials. They argue 25 years of consistent regulatory treatment supports their position that these products are not pesticides.

Are Black Berkey replacement filters available to buy?

 No authentic Black Berkey replacement filters are currently being manufactured due to the active SSURO. Pre-existing inventory sold out through 2024. Filters appearing for sale online at this time are very likely counterfeit. NMCL recommends purchasing only from authorized Berkey dealers and verifying authenticity before buying any Berkey-branded filter elements.

When might the Berkey filter shortage be resolved?

 NMCL reported in August 2025 that meetings with the Trump EPA administration were “productive” and expressed hope for a resolution in 2026. However, court proceedings and regulatory negotiations do not operate on guaranteed timelines. The active case in Puerto Rico (Case No. 3:24-cv-01106-CVR) has not yet produced a final ruling, and no trial date has been scheduled.

Is there a claim form for the Berkey water filter lawsuit?

 No active claim form or settlement website exists for any of the three Berkey lawsuits as of March 2026. The consumer class action has not publicly announced a settlement or claim period. The EPA cases are regulatory matters and do not produce consumer claim forms. If the consumer class action settles in the future, affected buyers of Black Berkey elements would likely be notified.

Where can I find official updates on the Berkey EPA case? 

Case 3 (Berkey International v. EPA) can be tracked through the federal court docket at PACER.gov under Case No. 3:24-cv-01106-CVR (D. Puerto Rico). The related First Circuit appeal is USCA Case Number 24-1917. NMCL publishes periodic updates at support.berkeywater.com. Authorized Berkey dealers also publish ongoing updates.
