Berkey Water Filter Review: What Happened and Should You Still Use One?

Updated February 2026 · 10 min read

The Bottom Line

The Berkey was once the most popular gravity-fed water filter among health-conscious families. Then in December 2023, the EPA issued a stop-sale order. Here's what actually happened, what it means for you, and what to use instead.

What Happened to Berkey?

If you've been in any mom group, crunchy parenting community, or emergency preparedness forum over the past decade, you've heard of Berkey. It was the gold standard. The filter everyone swore by. The one your friend with the organic garden recommended.

Then, seemingly overnight, it disappeared from shelves. Here's the timeline:

Key Fact

Berkey never held NSF certification for any of their filtration claims. Not one. Their testing was self-funded and not independently verified by a third-party laboratory.

What This Means For Current Berkey Owners

If you're reading this while glancing at the Berkey on your counter, take a breath. The situation is nuanced.

Why Berkey Was So Popular

I want to be fair here because I understand the appeal. For years, the Berkey checked every box that mattered to families like ours:

The Berkey wasn't just a filter. It was a symbol of taking control of your family's health. I get it. That's what makes this whole situation so frustrating.

The Certification Problem

Here's where I have to put on my researcher hat, because this is the part that matters most.

NSF International is an independent organization that tests water filters to verify manufacturer claims. When a filter is "NSF certified," it means a lab that doesn't work for the filter company has confirmed: yes, this product actually removes what it says it removes.

NSF certification means an independent lab verifies the claims. Without it, you're trusting the company's word. And when that company fights the EPA instead of simply getting certified, that tells you something.

What I Recommend Instead

For families who loved their Berkey, here are NSF-certified alternatives that I've researched and trust:

My Top Pick

AquaTru Countertop Reverse Osmosis

$449
NSF 42, 53, 58, 401, P473 · 84 contaminants verified

This is what I switched to. Reverse osmosis beats gravity filtration in independent testing, and it sits on your counter with zero plumbing — just like a Berkey. The filters last 6 months to 2 years depending on the stage. It's more expensive upfront, but every claim on the box has been independently verified.

Best Value

Clearly Filtered Water Pitcher

$90
NSF 42, 53, 244, 401, 473 · 365+ contaminants tested

If you're not ready to spend $449, the Clearly Filtered pitcher is a fantastic entry point. It removes more contaminants than any other pitcher on the market, and it's backed by real NSF testing. Great for families who want clean water now without a major investment.

Best for Homeowners

Aquasana Under-Sink Filter

$160 - $200
NSF 42, 53, 401

If you own your home and want a permanent solution, an under-sink system is the way to go. Aquasana's models connect to your cold water line and filter everything that comes out of that tap. Out of sight, out of mind — in the best way.

What I Use Instead

AquaTru — $449

The closest experience to a Berkey (countertop, no plumbing) with actual NSF certifications backing every claim. This is what replaced the Berkey on my counter.

The Verdict

4/10
Cannot recommend without NSF certification

I can't recommend the Berkey in 2026. Not because it definitely doesn't work — but because there's no independent proof that it does, the company fought the EPA instead of getting certified, and the Supreme Court sided against them. When it comes to my kids' water, "probably works" isn't good enough. I need the receipts.

If you're a current Berkey owner looking for a switch: the AquaTru is the closest experience (countertop, no plumbing) with actual NSF certifications backing every claim.

What Was Good

  • Gravity-fed, no electricity
  • Large capacity (2.25 gal)
  • No plumbing required
  • Durable stainless steel build

The Problems

  • No NSF certification — ever
  • EPA stop-sale order (2023)
  • Supreme Court declined appeal
  • Unavailable in the US
  • Self-funded, unverified testing
  • Replacement filters hard to source

Comparison: Berkey vs. the Alternatives

Here's how the Berkey stacks up against the certified alternatives I recommend:

Feature Berkey (Big Berkey) AquaTru Clearly Filtered
Price $280 (was) $449 $90
NSF Certified No Yes (42, 53, 58, 401, P473) Yes (42, 53, 244, 401, 473)
Contaminants Removed 200+ (self-reported) 84 (independently verified) 365+ (independently tested)
Filtration Type Gravity / Carbon Reverse Osmosis Affinity Filtration
Available in US No (stop-sale) Yes Yes
Plumbing Required No No No
Electricity Required No Yes No

Frequently Asked Questions

The Berkey is not technically "banned," but the EPA issued a stop-sale order against New Millennium Concepts (Berkey's parent company) in October 2023. The EPA classified the Black Berkey filters as unregistered pesticide devices because Berkey claimed they killed bacteria and viruses without obtaining the required EPA registration. Berkey appealed to the Supreme Court, which declined to hear the case in 2024. As of 2026, Berkey filters remain unavailable for sale in the United States.

If you already own a Berkey, the physical filter media hasn't changed — it still filters water. However, there are two concerns: the specific contaminant removal claims were never independently verified by a third-party lab like NSF, and replacement filters are increasingly difficult to find in the US. The EPA's order was a stop-sale, not a recall, so there is no legal requirement to stop using your existing unit.

Berkey never pursued NSF certification for any of their filtration claims. NSF certification requires independent laboratory testing that verifies a filter actually removes the contaminants a company claims it removes. Berkey relied on self-funded tests rather than independent third-party verification. The company never explained publicly why they chose not to obtain NSF certification, which is standard practice among reputable water filter manufacturers.

The best Berkey replacement depends on your budget and needs. For the closest experience to a Berkey (countertop, no plumbing), the AquaTru Countertop Reverse Osmosis system ($449) is our top pick — it holds NSF 42, 53, 58, 401, and P473 certifications and removes 84 verified contaminants. For a budget-friendly option, the Clearly Filtered Pitcher ($90) is NSF tested for 365+ contaminants. For homeowners wanting a permanent solution, the Aquasana Under-Sink system ($160-200) offers NSF 42, 53, and 401 certifications.
