20-inch Big Blue 3 Stage Filter Kit with Sediment, Activated Alumina, and Radial Flow Carbon Filter

The activated alumina filter removes lower levels of both arsenic and fluoride without any chemicals or hazardous byproducts.

The radial flow carbon filter provides a final barrier to chemicals, tastes, and odors while allowing for maximum flow rate.

This filter set can be used as an upgrade to your current 20" big blue system.
