What Are Common Contaminants in Drinking Water?

Contaminants can get in drinking water from all different kinds of sources. Many of which are from industrial processes, metal corrosion, and chemicals, such as preservatives and disinfectants.

Most contaminants can be removed from drinking water through reverse osmosis. This is a process of passing water under pressure through a semi-permeable membrane to remove the majority of contaminants. This is the most common process of filtering water. Kinetico’s K5 drinking water station, a reverse osmosis system with flex filtration, is certified to remove more contaminants than any other reverse osmosis system on the market.

For any contaminants that cannot be removed through reverse osmosis, or to further combat a specific contaminant, up to 5 filters can be added to the K5. Contact us to learn more.
