Original sentence: An alternative to iodine and other preparations in some usage scenarios are silver ion/chlorine dioxide based tablets or droplets.Sold under names like Micropur Forte, Aquamira, and Pristine, these solutions may disinfect water more effectively than iodine while leaving hardly any noticeable taste in the water in some usage scenarios.The primary disadvantages are the long purification times (generally 30 minutes to 4 hours, depending on the formulation used) and the fact that these chemical disinfection agents cannot provide any protection against the uptake of radioactive iodine into one's thyroid in a post-nuclear survival scenario.This disinfecting agent will kill Cryptosporidum and Giardia if utilized correctly
