Potable Aqua Chlorine Dioxide Tablets - 30 Pack

Purifying water couldn't be easier--simply drop a Potable Aqua® Chlorine Dioxide tablet into a quart of water and drink with confidence. Features the same proven technology used in municipal water supplies; effective against viruses, bacteria, giardia and cryptosporidium. Meets U.S. EPA purification guidelines; might take as long as four hours to kill contaminants in extreme situations. Each tablet is individually wrapped and sealed. While a 4-hour wait time may be inconvenient, alternative disinfectants do not claim to destroy cryptosporidium. Leaves no chemical aftertaste.
