Micropur Forte is composed of stabilised chlorine and silver ions. This molecule regulates the correct dosage of chlorine and quickly eliminates bacteria, viruses and some protozoa. At the same time, silver ions protect the water from recontamination for up to 6 months. Use 1 tablet per litre of water and leave for 30 minutes. For cold water (<10°C) or to destroy protozoa such as Giardia, allow to act for 2 hours.
