Reports highlight health risks stemming from the improper use of water filtration systems. Common errors include the assumption that filtration technology can safely treat highly contaminated sources, such as untreated well water or water with high iron and lime content. Such conditions can overwhelm and damage filtration membranes, potentially allowing toxins like arsenic, lead, and ammonium to pass through.

These failures can lead to serious medical conditions, including chronic kidney failure or cancer. Furthermore, poor hygiene at the dispenser, such as drinking directly from the faucet or sharing glasses, can turn the outlet into a transmission point for bacteria and viruses, including influenza, herpes simplex virus (HSV), and HP bacteria.
