Strain water through a regular water filter, coffee filter, or cloth to remove particulates. Water is now ready to drink or use for brushing your teeth, washing your hands/face, washing/cleaning your food. How Does Purinize Work? PURINIZE works through the process of Coagulation-Flocculation (CF). It contains a natural combination of coagulating and flocculating mineral salts that disinfect and clarifies raw water. CF removes suspended pollutants, in the form of microscopic particles or gross organic matter, by trapping them and clumping them together to form particulates. These entrapped particulates eventually settle and can be easily removed from the purified water by straining through a regular filter, coffee filter, or fine cloth. PURINIZE is the only water treatment product that naturally disinfects and clarifies water through the process of CF without chemical disinfectants or other synthetic ingredients. The CDC has compiled information on the CF process in the "Water Disinfection for Travelers Guide"
