Sweetwater ViralStop™

Sweetwater ViralStop is a chlorine-based purifier solution that provides simple and fast virus protection.  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.

ViralStop™ contains a special grade of Chlorine Solution, which prolongs shelf life and is EPA registered. Sweetwater has tuned the ViralStop™ solution 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 ™ 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 microfilter. Sweetwater does not recommend using ViralStop with any other filter.
