CFS RO Filter Kit for ROR2050 RS14 CB1 R200 with O-Rings, No Membrane

• THREE CARTRIDGES AND TWO O-RINGS - Replaces the RS14 polyspun sediment prefilter, the CB1 carbon block and the R200 inline carbon post filter in the RO2050 undersink system, with two housing O-rings included. This is the prefilter and post filter service; the membrane is not in this kit.
• WHY THE ORDER MATTERS - Sediment goes in first and holds back sand, silt and rust. The carbon block follows and reduces chlorine, which on an RO system does double duty: chlorine reaching the membrane is what shortens membrane life fastest. The inline post filter polishes the stored taste on the way to the faucet.
• WHEN TO CHANGE - Prefilters and post filter about every six months in typical use, sooner on water carrying heavy sediment. The membrane runs about a year, so a membrane change is roughly every second service - that kit is sold separately.
• 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: ROR2050, RS14, CB1, R200, RO2050.
• MATCH THE FILTER TO YOUR WATER - Cartridges are maintenance parts, not water treatment plans. Carbon reduces chlorine taste and odor; sediment media captures sand, silt, dirt and rust. For certified reduction of a specific contaminant, look for a system certified to the NSF/ANSI standard that names it. On a private well, start with a water test.

A three cartridge service kit for the RO2050 undersink reverse osmosis system, replacing the RS14 polyspun sediment prefilter, the CB1 carbon block and the R200 inline carbon post filter, with two housing O-rings in the box. This is the prefilter and post filter service. The reverse osmosis membrane is not included, because it runs on a longer interval than the cartridges around it. Order the stages the way the system runs them. Sediment goes first and holds back sand, silt and rust so the carbon behind it is not spending its capacity on grit. The carbon block follows and reduces chlorine taste and odor, and on a reverse osmosis system that stage earns its keep twice over, because chlorine reaching the membrane is the single thing that shortens membrane life fastest. The inline post filter sits last and takes off the flat, stored taste water picks up sitting in the tank before it reaches the faucet. Change the prefilters and post filter about every six months in typical use, sooner on water carrying heavy sediment. A membrane runs about a year, so a membrane change falls on roughly every second service and is sold separately. Do not reuse the old O-rings: most housing leaks are a flattened seal rather than cracked plastic, because the ring takes a set against the sump lip and stops springing back. Wipe the groove clean, seat the new ring and add a thin smear of silicone grease so it slides rather than rolls as you thread the sump up. Run a few minutes of water through the new carbon cartridge before use to clear loose carbon fines, which is normal on any new carbon filter. CFS is an independent brand.
