Health Effects of Lead
Lead is a potent neurotoxin with no safe level of exposure. In children, lead causes developmental delays, reduced IQ, and behavioral problems. In adults, it causes high blood pressure, kidney damage, and cardiovascular effects. Pregnant women face increased risk of premature birth.
How to Remove Lead From Drinking Water
The most effective treatment for lead removal is Reverse Osmosis or NSF 53 Carbon Block. Look for filters certified under NSF 53 / NSF 58 standards.
