## Overview

The Pentair Pentek CBC-10 is a 10-inch under-sink carbon block water filter cartridge featuring bonded powdered activated carbon that reduces chlorine, VOCs, and fine sediment down to 0.5 microns. Certified by NSF, it fits all standard 10" housings and delivers up to 20,000 gallons of clean, great-tasting water before replacement is needed. Perfect for residential, commercial, and RV use, it ensures premium water quality with minimal maintenance.

## Description

The Pentair Pentek CBC-10 is a bonded powdered activated carbon (PAC) block filter cartridge engineered for effective chlorine taste and odor reduction in potable water systems. With a 0.5 micron nominal rating, the CBC-10 delivers finer filtration than standard carbon block cartridges, capturing sediment and particulates while maintaining over 20,000 gallons of chlorine reduction capacity at a 1 gpm flow rate.The carbon block construction provides enhanced dirt-holding capacity compared to granular activated carbon (GAC) filters, making the CBC-10 suitable as both a standalone filter and a polishing or pre-filter in multi-stage systems. Operating temperature range is 40 to 180 degrees F with an initial pressure drop of less than 20 psi at 1 gpm.The CBC-10 fits any standard 10-inch by 2.5-inch filter housing and is used across residential, food service, commercial, and industrial applications. This 2-pack provides convenient replacement stock. Replace cartridges every 3 to 6 months or when a noticeable drop in water pressure or taste quality occurs. Certified to NSF/ANSI Standard 42 for material requirements.

Review: Best quality pick for price - Why did you pick this product vs others?: This is a direct brand replacement. I believe it is the best value filter you can get. It replaced our last filter we have been using for a year, way beyond it's volume and expiration period and still removes most of that reservoir water smell from the tap. This replacement along with a Brita filter pitcher for a fringe improvement gives us near snow melt well water quality you get in the high mountains in the spring. Our tap water isn't anywhere near the hard water you get from a southern California tap but has a bit of lake water smell, occasional mold fungus that immediately starts growing on the toilet bowl with a lot of new PVC pipe leaching into it, while on it's way here. Following any fungus blasts some kind of fungicide usually follows. Needless to say, a chemical reducing .5 micron biological safe water filter is a must here. This is the one that has led the pack for us.
Review: Good filter - Good filter.
