Utilizing 5 micron coconut shell activated carbon, it removes up to 99% of chlorine, organic compounds, and synthetic chemicals, improving water taste and odor while preserving healthy minerals. Compatible with most standard RO systems, it offers high filtration efficiency and comes with lifetime U.S.-based tech support and warranty registration.

## Description

From the manufacturer iSpring Carbon Block Filter (CTO) uses high quality coconut shell carbon and reduces fine sediment, chlorine taste and odor. Please note: This countertop water filtration system DOES NOT lower TDS value, instead it will keep healthy minerals in your water. If you are interested in a filter that eliminates TDS, please consider our iSpring tankless under sink Reverse Osmosis (RO) system RO500 or countertop RO water filter system RCT600.
