MSR Sweetwater ViralStop Solution
ViralStop is a chlorine-based purifier solution that provides simple and fast virus protection - just add 5 drops of ViralStop to each liter of filtered water, mix for at least 10 seconds, and wait 5 minutes. ViralStop comes in a spill-proof dispenser bottle for accurate measuring. Proven effective, chlorine is used to treat over 95% of all U.S. tap water. Most people believe it tastes much better than water treated with iodine-based products.
ViralStop contains a special grade of Chlorine Solution, which prolongs shelf life and is EPA registered. The ViralStop solution has been carefully tuned for the best possible combination of performance (fewer drops per liter = less weight to carry) and shelf life.
With ViralStop as a key component, the Guardian Purifier System meets stringent EPA standards and inactivates 99.99% of waterborn viruses and eliminates over 99.9999% of all waterborne bacteria and 99.9% of common protozoan parasites such as Giardia and Cryptosporidium.
Attention: ViralStop purifier solution has only been tested and approved for use with the Guardian microfilter.
