SHIELD Filtration
Crusader SHIELD Health-Related Contaminants filters remove up to 99.95% of PFOA, PFOS and cysts, plus up to 99.95% of soluble and particulate lead — whole-house protection from PFAS, lead and more.

Whole-house protection from PFAS, lead, cysts and more. Crusader SHIELD Health-Related Contaminants filters remove up to 99.95% of PFOA, PFOS and cysts (like Giardia and Cryptosporidium) and up to 99.95% of both soluble and particulate lead, while also capturing high levels of chlorine, chloramine and dirt.
This matters in Central Texas: in homes with pre-1986 plumbing, lead can leach into water as pipes corrode. A high-capacity 0.5-micron carbon-block design delivers excellent reduction with infrequent filter changes, and is made with FDA-approved, NSF 61-certified materials.
