Microbial Cysts and
Contaminated Water

Microbial Cysts Icon
Microbial cysts like Giardia and Cryptosporidium can enter lakes and rivers through human or animal feces and can live in cold water for up to several months. Cryptosporidium cysts are resistant to disinfection. This means they must be filtered out, rather than just treated through tap water chlorination.

Although Giardia has no long-term health effects, its symptoms include severe diarrhea, nausea, and stomach cramps, which can lead to dehydration, making it important to keep them out of your drinking water.
In 1993, 403,000 people in Milwaukee, Wisconsin got sick from a waterborne Cryptosporidium microbial cyst outbreak. PUR knew something needed to be done to prevent this from happening again. This led us to create the first pitcher filter with the ability to remove microbial cysts from your drinking water.
