That is what the radial flow format exists for.\u003c\/li\u003e\n\u003cli\u003eRadial flow means water enters through the outer wall and travels inward to the hollow core, passing through the full thickness of the carbon rather than along its length. On a cartridge this size that gives a large contact area at low resistance, which is the reason a whole house line can run carbon at all.\u003c\/li\u003e\n\u003cli\u003eA direct replacement for RFC20-BB and RFC20-BBSA cartridges, and the same standard size as EP20-BB, CBC-20BB, FLOPLUS-20BB, NCP-20BB, CB-45-2005 and WRC25HD20. If any of those numbers appears on the cartridge you are pulling out, this is the right replacement.\u003c\/li\u003e\n\u003cli\u003eCheck the size before ordering. These are 20 inches long and 4.5 inches wide, the big blue format, and not the 10 inch big blue or the slim line 2.5 inch cartridge. All three are white cylinders that look much the same in a photograph and none of them are interchangeable.\u003c\/li\u003e\n\u003cli\u003eCarbon exhausts rather than clogging. A sediment cartridge warns you it is finished by dropping your water pressure; carbon gives no such signal and simply stops reducing taste and odor while the flow stays the same. Change on a schedule, typically every six to twelve months. Compatible replacement made by CFS, not an original manufacturer part.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOverview\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Activated Carbon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 4.5\"D x 4.5\"W x 20\"H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Weight:\u003c\/strong\u003e 2.99 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Testing Certification:\u003c\/strong\u003e NSF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Benefits:\u003c\/strong\u003e Removes bad taste, odor, and chlorine for cleaner, better-tasting water.
