PUR Purifier of Water is both a flocculant and disinfectant that can separate particles and organisms from the water and kill microbes after 30 minutes. The water is then filtered through a cloth to remove the debris. The powdered product, which includes ferric sulphate and calcium hypochlorite, is delivered in small sachets.


The PUR Water Purifier has been field tested in six developing countries. Laboratory tests have shown it is effective in removing microbial and arsenic contaminants.
