Key Features

• ✅ABOUT PRODUCT: It is a package of 2 Large Capacity Carbon water filter cartridges that are compatible with WHA4BF5 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.
• ✅COCONUT SHELL CARBON BLOCK AT BIG BLUE SCALE – Coconut shell carbon is denser than coal based media, and pressing it into a solid block means water is pushed through the carbon rather than channeling around it. The 10 by 4.5 inch body holds enough media to keep whole house flow up while still giving contact time, reducing chlorine taste and odor and capturing the sand, silt and rust that wear on fixtures. Change it every 3 to 6 months.
• ✅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 WHA4BF5, WHKF-WHWCBB, CB-BB-10, CTO10BB, EPM-10BB and RFC-BB. Drops into any 10 by 4.5 inch Big Blue housing, including GXWH40L, GXWH35F, GNWH38S, RFC-BBSA and WFHD13001. Cartridges like WHKF-GD25BB are the same size and fit the same housing, but they are pleated sediment rather than carbon block, so expect different taste results.
• ✅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.
