P&G™ Purifier of Water is a powder that comes in small affordable, easy-to-use packets. It combines flocculation and disinfection to produce clean drinking water. Using some of the same ingredients used in municipal water systems, P&G™ Purifier of Water is engineered to be a mini-water treatment plant in a packet. The product removes dirt, cysts, and pollutants, and kills bacteria and viruses in polluted water such as creeks, rivers, lakes, and ponds. By removing the dirt and sediment through a flocculation process, P&G™ Purifier of Water gives a visible signal ensuring you have clean and fresh treated water. P&G™ Purifier of Water is simple to use, maintains a pure fresh taste similar to most household tap water, and is acceptable for drinking use after 30 minutes. A single packet treats 2.5 gallons / 10 liters of water. The P&G™ Purifier of Water packets are not intended to treat salt/ocean water.
