There is no safe level of lead in drinking water. NSF/ANSI 53-certified filters reduce lead to near-zero at the tap — protecting your family from a silent, serious health hazard.
The EPA has set an action level for lead in drinking water at 15 parts per billion (ppb), but the agency also states that there is no safe level of lead exposure — particularly for children, in whom lead causes irreversible neurological damage affecting IQ, behavior, and development.
Lead enters drinking water not from the original water source but from the plumbing it passes through on the way to your tap. Homes built before 1986 may have lead solder at pipe joints. Older cities often have lead service lines connecting the main water line to the home. Even newer homes may have brass faucets that leach lead. A certified lead water test is the only way to know your exposure level.
