Zero Technologies’ pour-through water filtration pitchers are the first to achieve certification for lead reduction.
NSF International announced that
Technologies LLC has obtained NSF certification for its pour-through water
filtration pitchers. Zero Technologies is the first company to achieve
certification of a filtration pitcher for lead reduction under the new
requirements of NSF/ANSI Standard 53: Drinking Water Treatment
Units ― Health Effects.
As of July 2007, all drinking water filters, including
pour-through pitchers, faucet mounts and built-in faucet filters, certified by
NSF must meet new test requirements for making claims of lead reduction under
NSF/ANSI Standard 53. Previously, the lead reduction test protocol did not
require a challenge with a specific percentage of particulate lead in addition
to soluble lead. The new test protocol requires that particulate lead must be
generated in the challenge water at a specific percentage.
Recent studies have indicated that lead contamination of
drinking water can occur in either or both particulate and soluble forms. Since
both forms of lead have adverse health effects if consumed, water treatment
products certified for lead reduction should be able to treat particulate lead
in addition to soluble lead.
NSF's Drinking Water Treatment Program tests and
certifies filters used to reduce contaminants, such as lead, from drinking
water. Certification to NSF/ANSI Standard 53 includes ongoing inspections of
the manufacturing facility and periodic testing to make sure the product does
not leach harmful levels of metals or other contaminants into drinking water
and continues to perform as originally certified.
The requirements were adopted into NSF/ANSI Standard 53
in February 2007 with approval from the NSF Joint Committee on Drinking Water
Treatment Units, an independent consensus standards body composed of a balanced
representation of stakeholders including regulators, industry representatives
and product users. Manufacturers were also notified of the new requirements at
