Are AQUATABS® water purification tablets effective against the cysts Giardia and Cryptosporidium?
AQUATABS® are effective against Giardia when used as directed. Usually a double dose is required in very cold water (5C).AQUATABS® are not however effective against Cryptosporidium when this cyst is in the oocyst stage of its life cycle. Cryptosporidium is however not considered to be a common cyst. For more information about Cryptosporidium please refer to “Water 101”. If Cryptosporidium is suspected, boil the water for 1 to 3 minutes depending on elevation or filter to a level of 1 micron absolute and then treat with AQUATABS® to inactivate remaining bacteria and viruses that filtration does not generally remove.
