About This

• Two grooved sediment cartridges at 5 micron in the 20 by 2.5 inch slim size, a direct replacement for the Housepure Secure WI-HP-SECURE-.75C cartridge. At a six month change that covers a full year on one system, which is the interval most heater manufacturers ask for.
• Sediment protection for tankless heaters: it captures sand, silt, rust and scale-forming particles before they reach your heat exchanger, helping maintain flow and protect the appliance. On a tankless unit that matters twice over, because falling flow is what triggers the nuisance faults.
• Grooved rather than smooth-walled: the ridged outer surface adds filter area compared with a plain cylinder of the same dimensions, so sediment collects across more of the face. That gives higher dirt holding and steadier flow for longer before your pressure starts to drop.
• Check the length before ordering, because this is where most wrong orders happen. This is the 20 inch cartridge, not the 10 inch, and it is the slim 2.5 inch diameter rather than the wide big blue format. All three look broadly alike in a photograph and none are interchangeable, so measure the one you are replacing.
• This is sediment media: it captures particles and nothing else. There is no carbon in it, so it does not reduce chlorine, taste or odor, and it does not prevent scale chemically. What it does is keep the particulate that carries scale out of the appliance. Replace about every six months or per your heater manufacturer guidance. CFS is an independent brand, a compatible replacement and not an OEM part.
