These Puritabs just got better, they are now in powder form to make them quicker and easier to dissolve making them more effective. They are made for the US Forces and are very effective. They will sterilise water even against Giardia, Bacteria, Viruses and all the normal water-borne contaminants. Anything that has been made for the US Military is some of the best kit in the World as they don't scrimp on costs when it comes to equipping their troops.
They are the current issue powder and, in our opinion, they are without competition. All purification tablets, drops or powder sterilise water to some degree or another but these have the added bonus of bonding to sediment and actively cleaning the water. It contains Chlrofloc which a chemical that actively bonds to sediment and separates it from the clean water.
