California Prop 65 Warning FAQ


Why are you including a Prop 65 warning?

California voters passed Proposition 65 (also known as Prop 65) in November 1986 which requires the state to publish a list of chemicals that, in the state's opinion, can cause cancer, birth defects or other reproductive harm.

It also requires businesses to inform Californians if any products sold in California include any of these chemicals.

The Prop 65 list includes approximately 900 chemicals, more than are included on similar lists from the federal government and other states.


I purchased this product outside of California. Why am I seeing the Prop 65 warning?

Oransi products are sold nationwide. To make sure all products sold in California comply with Prop 65, we include the warnings on every Oransi product.


Are your products safe to use?

All Oransi products meet or exceed federal and state safety requirements, and are safe when used as instructed. All Oransi air purifiers are certified by the California Air Resources Board (CARB), part of the California EPA. "To be certified, all air cleaners must be tested for electrical safety...Mechanical: Air cleaners that are listed as "Mechanical" are those that only use physical filtration, such as pleated or HEPA-style filters, and do not generate ozone or ions."

We have certified our mod and mod jr air purifiers to the RoHS (Reduction of Hazardous Substances). This directive restricts the use of hazardous materials of electrical products.

A Prop 65 warning alerts consumers that a product contains one of the approximately 900 chemicals on California’s list. It does not mean a product is unsafe.

For example, cadmium and lead are chemicals on the Prop 65 list and commonly found in the soldering on circuit boards. Lithium-ion batteries can expose you to chemicals such as cobalt lithium nickel oxide or nickel.


Doesn’t the State of California require evidence of harm to humans prior to placing a chemical on the Prop 65 list?

No. Chemicals may be placed on the Prop 65 list based on “epidemiological studies, animal studies, or other relevant data.” For more information on this process, see how Prop 65 chemicals are selected from the Office of Environmental Health Hazard Assessment (“OEHHA”). 


What is the risk that I will develop cancer or suffer reproductive harm from these products?

A chemical’s inclusion on the Prop 65 list does not necessarily mean there is material risk of cancer or reproductive harm. Per the CA state website "A Proposition 65 warning does not necessarily mean a product is in violation of any product-safety standards or requirements."
