About Prop65

We know that some customers are concerned about the Prop 65 warning listed on our products. So instead of leaving it as a mystery, let’s talk about what is the Prop 65 warning and why it is listed on our products.

What is Proposition 65?

In November 1986, California voters approved a ballot initiative to address concerns about exposures to toxic chemicals. That initiative became the Safe Drinking Water and Toxic Enforcement Act of 1986, better known by its original name, Proposition 65 or simply, Prop 65.

New regulations affecting Proposition 65 were adopted in August 2016 and have taken full effect in August 2018. Changes to the law impose additional requirements for products sold in California, including:

  • 1. Point of sale warning requirements
  • 2. The specific identification in the warning language of at least one chemical known to cause cancer and/or birth defects that are used in a given product


How many chemicals are included under Prop 65?

As of March 8, 2019, more than 800 chemicals and materials have been listed under Prop 65 warning. Prop 65 warnings are seen throughout California in a wide range of settings and on a wide variety of consumer products that we use everyday, including coffee, furniture and automobile upholstery, wall coverings, housewares, automotive parts, and so on. Even Starbucks and Disneyland Resort in California are required to have Prop 65 warnings. The complete Proposition 65 List is available at https://oehha.ca.gov/proposition-65/proposition-65-list.


Does a Prop 65 warning equal unsafe?

No. Prop 65 is far more stringent than FDA and EU standards. Prop 65 Warnings are required for even tiny levels of these natural substances - sometimes a 1000 times less than the minimum safe dose established by health authorities. A Prop 65 warning does not automatically mean that the product is unsafe.


Why is Prop 65 listed under our products?

The polyvinyl chloride (PVC) sheet used to make the fittings and housings of our water filtration systems may include vinyl chloride monomer, which is known to the State of California to cause cancer. The chemical intermediate in the production of PVC is required to have a Prop 65 warning by the State of California. Although the system may contain PVC, no chemicals will leach into the water. All water-contacting parts are made of BPA (Bisphenol A) free materials.

How can I get more information?
