If you are concerned about lead in your water, look for a filter that is certified to NSF Standard 53. This indicates a filtration system designed to reduce specific health-related contaminants, including lead. Everydrop water filters 1-5 are NSF certified to reduce 99% of lead[1] and other heavy metals from tap water. In addition, they are also certified to reduce asbestos and a range of industrial chemicals.
NSF International is an independent organization that certifies filters against three contaminant categories: look and taste, health concerns, and emerging (or new) contaminants. While some filters may qualify for one or two of the categories, everydrop filters 1-5 are certified for all three.
[1]Certified by NSF International to remove 99% of lead at pH level 6.5. Reduction may vary based on your water's pH level. Contaminants reduced by this water filter are not necessarily in all users’ water.
