What water filtration system filters can remove Cryptosporidium?

Water filtration systems that remove Cryptosporidium include reverse osmosis (RO) drinking-water units, UV disinfection systems, and filters specifically certified for cyst reduction. Cryptosporidium is a chlorine-resistant parasite, so effective control relies on very fine membranes, targeted disinfection, or both rather than standard taste-and-odor filters.

We install whole-home purification options and point-of-use RO systems, and can pair UV disinfection when microbial control is a goal; we see these combinations work well for local homes while keeping maintenance practical. Water softeners improve hardness but are not designed to remove microbes like Cryptosporidium.

• Use RO at a kitchen tap for high-quality drinking and cooking water.
• Add UV on the main line when you want whole-home microbial inactivation.
• Choose a filter labeled for “cyst reduction” if selecting a non-RO option.

Verify any chosen system is independently certified for cyst reduction and follow the filter change schedule before relying on it for drinking.
