About This

• ✅ABOUT PRODUCT: It is a package of 4 Carbon Block filter cartridges compatible with HDX HDLORF4, GE FX12P water filter cartridges. It has a larger surface area and has a longer filter life. This water filter cartridge removes more pollutants by providing "depth" filtering.
• ✅TWO YEARS OF STAGES IN ONE BOX – A three stage RO runs a carbon block ahead of the membrane and another behind it, so one service takes two cartridges. Four gives you two full changes. The front cartridge takes chlorine out before it reaches the membrane, which is what shortens membrane life fastest. The rear one polishes the flat, stored taste water picks up sitting in the tank.
• ✅BETTER-TASTING WATER FROM EVERY SOURCE – Whether your home runs on municipal tap water or a private well, the carbon reduces the chlorine taste and odor that make water unpleasant to drink and cook with — better-tasting water from the system you already own. For certified reduction of specific contaminants, look for cartridges tested to NSF/ANSI 53 for those claims.
• ✅FITS THESE PART NUMBERS – Direct replacement for the HDLORF4 drop-in set and the GE FX12P set, Home Depot item 1000991168. These seat in the GXRM10RBL, GXRM10G, PNRV12, PNRV12Z, PNRV12ZBL and GXRV10 three stage systems. The membrane is a separate part, sold as FX12M, and is not included here.
• ✅MATCH THE FILTER TO YOUR WATER – Cartridges are maintenance parts, not water treatment plans, and no single one handles everything. Carbon reduces chlorine taste and odor. Sediment media captures sand, silt, dirt and rust. For any specific contaminant you are concerned about, look for a system certified to the NSF/ANSI standard that names it. If you are on a private well, start with a water test.
