## Overview

Certified by NSF, it fits all standard 10" Big Blue housings and delivers up to 12,500 gallons of clean, odor-free water by effectively reducing chlorine taste, odors, and suspended particles.

## Description

Pentair Pentek GAC Series Cartridges effectively reduce unwanted tastes and odors, including chlorine taste & odor from your drinking water. They are designed to allow maximum contact between the water and carbon, ensuring optimal adsorption. The construction of the cartridge allows water to enter at one end and pass through the entire length of the carbon bed before exiting the other end of the cartridge, while an internal expansion pad minimizes channeling or bypass. Before the water exits the cartridge, a post-filter helps reduce carbon fines and other suspended particles from the filtered water. The post-filter is permanently fastened to an innovative support basket ensuring that it is firmly se d and eliminating any potential for bypass. GAC Series Cartridges are available in a variety of sizes and flow rates, and effectively provide good general-purpose drinking water filtration.

Review: No other filters clean the water, and last as long as these.
Review: We had a problem with our well having a higher uranium count than good for drinking purposes, used this product and it lowered the count, this is used along with a water softener and ro system.
