"lead, mercury and arsenic" As the manufacturer of this product you're going to want to be very careful making claims like that in a public forum. I see no evidence of CDPH certification, despite the product being sold from San Francisco: When a manufacturer claims that a drinking water treatment device will reduce contaminants [such as lead, Cryptosporidium (protozoan cysts), pesticides, herbicides, solvents, heavy metals, bacteria and viruses] or makes other health related performance claims, the device must be certified by CDPH, pursuant to Health & Safety Code Section 116830. http://www.cdph.ca.gov/certlic/device/pages/watertreatmentdevices.aspx http://www.cdph.ca.gov/certlic/device/pages/watertreatmentde...
