Important limitations
This is a preliminary screening product, not a certification that water is safe to drink. Although the supplier listing mentions E. coli, it does not document a validated microbial testing method or substantiate the claimed accuracy and certifications. For suspected contamination, use an accredited laboratory test or contact your water authority. The number of strips per pack and included accessories have not been confirmed.
