Maybe you didn't know that microbial cysts enter water supplies from animal feces, but you probably do know that anything that comes from animal feces shouldn't be in your drinking water.1
Both giardia and cryptosporidium are microbial cysts—and they are tough to disinfect. What makes them tough is the way they operate. These microbes grow a cyst wall around themselves for protection in unfavorable conditions.2 When giardia and cryptosporidium reach more favorable environments like your stomach, their cyst walls break down and the microbes inside them release to potentially cause gastrointestinal illness like diarrhea, nausea and stomach cramps. According to the EPA, cryptosporidium is resistant to disinfection.1

It's also why PUR reduces up to 10x more drinking water contaminants than the leading filtration brand's pitcher3—leaving you and your family with clean drinking water.
MICROBIAL CYSTS IN WATER AND THEIR EFFECTS ON YOUR HEALTH:
Cryptosporidium is a microbial cyst that is commonly found in lakes and rivers that can cause gastrointestinal illness. It enters the water through animal and human fecal matter.2
The microbial cyst giardia is a one-cell parasite that infects humans and animals in the cyst stage of their life cycle. It enters the water through animal and human fecal matter.2
