California State Certification Water Treatment Device Certification Information

Notice: consumer is responsible for following any state and/or local regulations and plumbing codes pertinent to the purchase, installation and operation of our products.

Note to California Residents:

The state of California has adopted its own water treatment device certification program independent of all other states and recognized certification programs.

California requires drinking water treatment devices with health performance claims to be tested and certified by a state approved laboratory.  Our units are not certified for sale in California.  Therefore, we no longer ship completed filter systems to California addresses.

Shower filters are not regulated and we can ship shower filters to California residents.
