The state of California has established regulations and procedures for the sale of indoor water systems. Under these regulations, the state of California requires that any water treatment system that is sold in the state first be certified by an independent, third-party testing agency, such as NSF, before the system can be considered eligible for sale in California. NSF Standard 42 (aesthetic effects) and Standard 53 (health effects) would specifically  apply to our purification elements.

NSF Standard 42 covers systems “designed to reduce specific aesthetic or non-health-related contaminants such as chlorine, taste and odor, and particulates that may be present in public or private drinking water. NSF Standard 53 addresses  “systems designed to reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, Volatile Organic Chemicals, MTBE that may be present in public or private drinking water.”

The tests we have conducted are much more rigorous than those required by NSF for the certifications mandated by the state of California. Our purifiers have been rigorously tested by third-party independent accredited labs far surpassing the above standard of taste, odor and chlorine reduction. For example, our systems have been tested for the removal of hundreds of contaminants including heavy metals, pesticides, herbicides, pharmaceuticals, pathogenic bacteria and viruses. These test results are published and available to all our consumers on our website as well as published in our printed literature. In addition, there has also been other highly publicized and notable testing of our purifiers against other so-called similar water filtration systems which clearly back up our third-party testing. Although our extensive testing is sufficient for 49 states in the US, it is currently not acceptable for residents of the state California.

Once NSF certification has been obtained, the state of California additionally requires that companies pay high costs to obtain and maintain certification with the state of California.

In the end, we have concluded that the additional taxes, certifications and red tape have created too large of a barrier for our firm to offer our systems in the state of California
