Key Features

• COMPLETE PRE-FILTER SET - Everything the system needs for a scheduled change in one box, sized and ordered for the stages as the manufacturer laid them out. Cartridges are standard dimensions and drop into the housings already on the unit.
• FITS STANDARD 10 IN x 2.5 IN HOUSINGS - These are standard size cartridges and drop into any 10 in x 2.5 in reverse osmosis, under sink or countertop housing. No specific system model is required. CFS is an independent brand and this is not an OEM product.
• CHANGE THEM AS A SET - Stages work in sequence: the sediment cartridge takes the grit before it reaches the carbon, and the carbon takes the chlorine before it reaches the membrane. Replacing one and leaving the others in place lets the tired stage load the fresh one. Changing the pre-filters together on one schedule is what keeps the system working as designed.
• A YEAR OF SERVICE IN ONE BOX - Pre-filters typically run about 6 to 12 months depending on feed water and household usage; membranes go longer. Having the full set on hand means the change happens when it should rather than when the replacement finally arrives.
• WHAT YOU GET AND WHAT YOU DO NOT - This is a replacement cartridge set for a system you already own. It does not include the housings, the manifold, the tank or the faucet. Cartridges are standard sizes and go in with the housing wrench that came with the system.
