CFS 5 Micron Carbon Block Compatible with WHA2BF5, GE FXWTC, WFPFC8002 - 4 Pack + 2 O-Rings

• FOUR CARTRIDGES AND TWO O-RINGS - Four 5 micron carbon block cartridges in the standard 10 by 2.5 in size, with two housing O-rings in the box. Direct replacement for WHA2BF5. Four covers roughly two years on a six month change.
• COCONUT SHELL CARBON BLOCK, NOT LOOSE GRANULES - The carbon is formed into a solid block rather than packed as granules, so water is forced through the carbon instead of finding channels around it. That is what makes a block reduce chlorine taste and odor more consistently than a granular cartridge of the same size, and it holds fine particulate at 5 micron on the way through.
• CHANGE THE O-RING WITH THE CARTRIDGE - Most housing leaks are a flattened seal, not cracked plastic: the ring takes a compression set against the sump lip and stops springing back. Two rings are included so the seal gets replaced when it matters. Wipe the groove clean, seat the new ring, and add a thin smear of silicone grease so it slides rather than rolls as the sump threads up.
• COMPATIBLE REPLACEMENT, NOT AN ORIGINAL MANUFACTURER PART - CFS is an independent brand. This is a compatible replacement, not an original manufacturer part, and manufacturer names and part numbers are used for reference only to show what it fits: WHA2BF5, FXWTC, WFPFC8002, WHCF-WHWC and SCWH-5.
• WHEN TO CHANGE IT - Plan on about six months. Carbon does not clog visibly the way sediment media does; it exhausts, and the sign is chlorine taste returning at the tap. If flow drops off instead, that is sediment loading, and the answer is a sediment stage ahead of this one rather than changing the carbon sooner.

Four 5 micron carbon block water filter cartridges in the standard 10 by 2.5 in size, with two housing O-rings included, a direct replacement for WHA2BF5. The carbon here is formed into a solid block rather than packed in as loose granules, and that distinction is the whole point of the cartridge. Water forced through a solid block cannot find channels around the media the way it can through granular carbon, so chlorine reduction stays consistent across the life of the cartridge instead of falling away as channels open up. At 5 micron the block also holds fine particulate on the way through. Two O-rings are in the box because the seal is the part most often reused when it should not be: a ring takes a compression set after months clamped against the sump lip, and once flattened it will not seat the same way again. Most housing leaks are a tired O-ring rather than cracked plastic. Wipe the groove clean before seating the new one, then add a thin smear of food grade silicone grease so the ring slides into place rather than rolling or pinching as the sump threads up. Plan on about six months per cartridge. Carbon does not clog visibly the way sediment media does - it exhausts, and the signal is chlorine taste coming back at the tap rather than pressure dropping. If what you are seeing is falling flow, that is sediment, and the fix is a sediment stage ahead of this one rather than changing the carbon sooner. Fits WHA2BF5, FXWTC, WFPFC8002, WHCF-WHWC and SCWH-5, and standard 10 by 2.5 in housings generally.
