These effervescent tablets are formulated using sodium dichloroisocyanurate, an organic chlorine-based disinfectant. Each tablet treats up to 25 litres of water, with a 32-tablet pack capable of purifying approximately 800 litres. The tablets dissolve rapidly and are individually foil-wrapped for stability, offering a shelf life of over five years and broad-spectrum effectiveness against bacteria, viruses, and other microorganisms.
