Independent testing has demonstrated significant reductions across bacteria (including E. coli), viruses (MS2 99.9999%), heavy metals including lead and mercury, chlorine and chloramines, pesticides, PFAS (forever chemicals), and microplastics.

Because gravity systems leave healthy, natural minerals intact, you may notice cosmetic limescale or limestone buildup inside the stainless steel chambers over time. This is entirely normal. Simply spray the empty chambers with a 50/50 mix of water and white vinegar, let it sit for 15 minutes, gently wipe with a soft cloth or brush, and rinse thoroughly.

This is perfectly normal and caused by harmless residual carbon dust from the manufacturing process. Simply prime your filters according to the instructions and discard the first two full filtration cycles before regular drinking.
