Pharmaceuticals in water can cause biological effects and ecological accumulated in organisms such as mammals, fish, amphibians and reptiles, and may be associated with health problems in humans. In fact, many water treatment facilities may not be able to remove 100% of these types of manufactured compounds or substances. ONEWATER® filters reduce trace levels of pharmaceuticals by 99%.
