Quick Answer
Berkey water filters are not "banned" in California - they simply lack the required state certification for sale. Owning or using a Berkey in California is perfectly legal. California requires all water treatment products making health claims to be certified by the State Water Resources Control Board. Berkey has chosen not to pursue this certification, so retailers cannot legally sell Berkeys to California addresses.
The Full Story
The California water filter situation is often misunderstood. Many people think there's something wrong with Berkey filters.
Others believe California has targeted the brand. However, the reality is more bureaucratic.
What People Think
- • California discovered Berkey filters are unsafe
- • Berkey failed government safety tests
- • Using a Berkey in California is illegal
- • Berkey is hiding something
The Reality
- • It's a certification paperwork issue
- • Berkey hasn't submitted for CA testing
- • Owning/using Berkey in CA is legal
- • Berkey objection is to process, not results
California Health and Safety Code Section 116830 is the key regulation here. The law requires certification from the California State Water Resources Control Board.
This applies to any water device sold in the state. All products that claim to treat, filter, or improve water quality must be certified.
This includes both point-of-use and point-of-entry treatment devices.
California Certification Requirements
California has some of the strictest water filter rules in the country. The state wants to protect consumers from ineffective products.
To legally sell a water treatment device in California, manufacturers must meet these five requirements:
Third-party lab testing
Independent verification of contaminant removal claims
California-specific test protocols
Testing must follow California State Water Board procedures
Annual certification renewal
Products must be recertified each year
Manufacturing facility inspection
Production facilities may be subject to inspection
Labeling compliance
Specific California labeling requirements must be met
Why This Matters
These requirements exist for good reason. Some companies have marketed ineffective or harmful water filters in the past.
These products gave consumers false confidence. California's rules ensure products actually do what they claim.
Berkey's Response
Berkey has publicly addressed the California situation. The company has explained why they won't pursue certification. Here's their position:
Berkey says their independent lab testing exceeds California's standards. Their filters remove more contaminants than required.
Their testing data is not in California's required format. This means they would need to do duplicate testing.
The certification process is expensive and takes a long time. Berkey decided it's not worth the investment.
Berkey continues to sell in 49 other states and internationally without issues.
"Our test results show that Black Berkey® Purification Elements far exceed any other gravity filter element available today. However, California requires testing in a specific format. This means we would need to duplicate our existing testing."
- Paraphrased from Berkey official communications
Legal Options for California Residents
If you're a California resident who specifically wants a Berkey, you have several legal options:
Purchase While Traveling
Buy a Berkey in Nevada, Arizona, Oregon, or any other state while traveling. Then bring it back to California yourself. This is completely legal.
Ship to Out-of-State Address
Have the system shipped to a friend or family member in another state. You can also use a PO box. Then pick it up or have them send it to you.
Buy Used
The law restricts commercial sales only. Private party sales between individuals work differently. These are not regulated the same way.
Receive as Gift
Have someone outside California purchase it as a gift and ship it to you. The restriction is on sales, not gifts.
Important Clarification
Owning a Berkey water filter in California is 100% legal. Using one is also perfectly legal.
The restriction only applies to commercial sales within the state. You cannot be penalized for having one in your home.
