why are berkey water filters banned in california

If you’ve ever asked why are berkey water filters banned in california, the answer lies in state rules, not in product safety. Berkey filters meet national standards but do not follow California’s special steps for certification, labeling, and registration. This article breaks down each rule, explains Berkey’s decision, and shows what options remain for residents.

why are berkey water filters banned in california: California’s filter requirements

California enforces three main rules for home water filters. Missing any one makes a product illegal to sell in the state.

Proposition 65 warning labels

• What it is: A list of chemicals linked to cancer or reproductive harm.

• Requirement: Products that expose users to any listed chemical must carry a clear warning label.

• Why it matters: Companies must track updates to the list and add labels when needed.

NSF/ANSI certification

• What it is: Third-party testing under NSF/ANSI standards:

  • 42 for taste, odor, and chlorine removal

  • 53 for health-related contaminants like lead and cysts

• Requirement: Submit each model for testing and pay fees for initial and annual renewals.

State registration with Water Boards

• What it is: A public list of approved filters.

• Requirement: Each model must appear on the California Water Boards register before sale.

why are berkey water filters banned in california: Berkey’s decision

Berkey filters perform well in independent labs, but meeting California’s steps meant extra cost and sharing design details.

Private design and testing

• Berkey uses EPA-accredited labs to prove its filters work.

• California certification would require revealing the exact filter design and grant state access to test methods.

Cost and administrative burden

• Fees for NSF/ANSI testing and state registration add up each year.

• Monitoring Proposition 65 changes and updating labels creates ongoing work.

By opting out, Berkey chose to keep its design private and avoid added costs. As a result, full-size indoor models are not listed in California and cannot be sold there.

Alternatives for California residents

If you live in California and need an indoor filter, look for systems that meet all three steps:

• Prop 65 compliant: Clear warning labels if chemicals are on the list

• NSF/ANSI certification: Valid 42 and 53 certificates with renewal dates

• State‐registered: Model numbers listed on the California Water Boards site

Key search terms: “California water filter laws,” “NSF/ANSI 42 California,” “Prop 65 water filter,” and “California filter registration.”

Detailed information summary

Conclusion

Knowing why are berkey water filters banned in california helps you choose a filter that fits both your needs and state rules. Berkey opted out of California steps to protect its design and limit costs, so its indoor units are not sold there. Residents can still use Berkey Light and Travel models (for outdoor or emergency use), or pick another filter that carries Prop 65 labels, NSF/ANSI certificates, and appears on the state register.

Major FAQs on “why are berkey water filters banned in california”

1. Why are berkey water filters banned in california?
   Berkey systems are not sold in California because the company chose not to meet three state requirements:

   • NSF/ANSI certification under standards 42 and 53 with annual renewals

   • Proposition 65 warning labels for any listed chemicals

   • Registration of each model with the California Water Boards
     Without these steps, full-size Berkey units cannot be legally shipped or sold in the state.

2. Why are berkey water filters banned in california even though they use NSF-certified filter elements?
   Although Berkey filter elements pass NSF/ANSI tests in accredited labs, California requires separate state-level certification and fees. Berkey opts out to protect its design and avoid added costs, so its national certifications alone are not enough for California compliance.

3. Why are berkey water filters banned in california but still sold as Berkey Light and Travel models?
   California’s rules apply only to in-home devices. Berkey Light and Berkey Travel are marketed as emergency or outdoor units, which are exempt from the state’s in-home filter certification and registration requirements.

4. Why are berkey water filters banned in california and what would they need to do to comply?
   To sell full-size units in California, Berkey would need to:

   • Submit each model for NSF/ANSI 42 and 53 testing and pay annual renewal fees

   • Add clear Proposition 65 warning labels if any listed chemicals are present

   • Register all models with the California Water Boards before sale
     Meeting these steps would allow legal in-state sales.

5. Why are berkey water filters banned in california when other brands meet state rules?
   Competing brands choose to:

   • Share design details for independent testing

   • Pay certification and renewal fees each year

   • Maintain Proposition 65 warning updates
     Berkey’s decision to keep its design private and avoid extra costs means it does not follow California’s additional steps, so other brands that comply can be sold in the state.
