When makers of water filtration systems claim that their treatment device is capable of removing contaminants from drinking water or makes other claims that are related to health, it must get certified by the California Department of Public Health (CDPH). A certificate from the CDPH, as stated on their website, means that “the device has been tested by an independent, state-approved laboratory (1) to verify the manufacturer’s health-related performance claims, and (2) to ensure that materials within the device do not add contaminants to the treated water.”
The Water Treatment Device Certificate given to the water filtrations systems provide by Aquasana, certificate number 06-1792 for the AQ-4000 model, was officially issued on July 28, 2006. It certifies that the independent tests of the filtration system done by a laboratory approved by the State of California’s Department of Health and Services proved the claims by Aquasana that the system removes at least 54 common contaminants. The AQ-4000 drinking water system from Aquasana was tested and has received this certificate.
These contaminants include lead, cysts, MTBE, all VOCs, the four major haloacetonitriles, and trihalomethanes, just to name a few. Aquasana filtration systems were rated a Best Buy in Consumer Digest for 6 years in a row for this reason as well as its exceptional value and convenience. Aquasana simply produces the best water filtration systems available on the current market.
