CFS 15 Pc Sediment GAC Carbon Sets 10x2.5 for WHKF-GD05 GAC-10 WHWC

• 5 COMPLETE SETS, 15 CARTRIDGES - Each set is one sediment cartridge, one granular carbon cartridge and one carbon block, all 10 by 2.5 in. 5 sets covers 5 full services of the system, so the next change is on the shelf rather than ordered in a hurry.
• THREE STAGES IN EACH SET - Sediment goes first and holds sand, silt, dirt and rust. Granular carbon follows and reduces chlorine with little pressure drop. The carbon block runs last of the three, compressed rather than loose, so water cannot channel around the media and it catches finer particulate as well.
• WHY GAC AND A BLOCK TOGETHER - Loose granular carbon flows freely and keeps pressure up; a compressed block gives more consistent contact. Running both in sequence is a large part of why a multi stage system tastes better than a single carbon cartridge, and each stage protects the one behind it.
• PART NUMBERS AND HOUSINGS - Replaces WHKF-GD05, GAC-10, WHKF-WHWC, AP110, WHKF-DB1, CG5-10S, UDF-10 and CTO-10 positions, and fits standard 10 by 2.5 in slim line housings on reverse osmosis and under sink systems. This is not the 10 by 4.5 in big blue size; measure before ordering.
• MATCH THE FILTER TO YOUR WATER - How fast a set loads depends on your supply and how much water you run. Well water or heavy sediment typically means changing sooner; light municipal use typically stretches the interval. Falling pressure or a return of chlorine taste is the signal, not the calendar.

Complete three stage cartridge sets in the standard 10 by 2.5 in slim line size: a spun sediment cartridge, a granular activated carbon cartridge and a carbon block, one of each per set. Buying several sets at once means the system is serviced on schedule rather than whenever the last cartridge finally gives out. The three stages run in sequence and each one makes the next work better. Sediment goes first and holds particulate, meaning sand, silt, dirt and rust, before it reaches anything behind it. The granular carbon follows: packed loose, so water moves through it freely with little pressure drop, reducing chlorine along with the tastes and smells that come with it. The carbon block comes last of the three and is compressed rather than loose, so water cannot channel around the media. That gives more even contact and catches finer particulate at the same time, which is a large part of why a multi stage system tastes better than a single carbon cartridge would. Fitment covers WHKF-GD05, GAC-10, WHKF-WHWC, AP110, WHKF-DB1, CG5-10S, UDF-10 and CTO-10 positions and standard slim line housings on reverse osmosis and under sink systems. Check the size before ordering: this is the 10 by 2.5 in cartridge, not the 10 by 4.5 in big blue, and the two are easy to confuse in a photograph. Use the size selector on this page to choose how many complete sets you need. How long each set lasts depends entirely on your water and your household, and falling pressure or a return of chlorine taste at the tap is the signal to change rather than a date on the calendar. Complete Filtration Services has built and supplied replacement filtration since 2006.
