CFS 3 Pc Sediment Carbon and 100 GPD Membrane Set for Stealth RO100

• ABOUT PRODUCT: It is a package of 1x Sediment Cartridges of 1 Micron Rating, 1x Carbon Block Cartridges of 1 Micron Rating and 1x Membrane of 100 GPD compatible with RO100 water filter cartridges. It has a larger surface area and has a longer filter life. This water filter set removes more pollutants by providing "depth" filtering.
• COMPLETE THREE-PIECE SERVICE SET - One sediment cartridge, one carbon block cartridge and one 100 GPD reverse osmosis membrane, shipped together in a single box. This is everything the system needs for a full service, so you are not tracking down three separate part numbers when the water slows down or the taste changes.
• HOW THE THREE STAGES WORK TOGETHER - The sediment cartridge goes first and holds the sand, silt, dirt and rust that would otherwise reach the stages behind it. The carbon block follows and reduces chlorine and the tastes and smells that ride with it, which also protects the membrane, since chlorine shortens membrane life. The 100 GPD membrane runs last and reduces dissolved solids. Replacing the prefilters on schedule is what keeps the membrane working as long as it should.
• PURER WATER FROM EVERY SOURCE - On municipal tap or private well supply, the membrane strips dissolved solids - low-TDS water for drinking and cooking from the system you already own. RO reduces TDS broadly; for certified reduction of specific contaminants, look for systems tested to NSF/ANSI 58 for those claims.
• FITS THE STEALTH RO100 - Sized for the Stealth RO100 system. The membrane in this set is rated at 100 GPD, which is the figure to match: the drain-line flow restrictor is paired to membrane output, so a set built around a different GPD rating will not run the way the system was set up to run. If your system uses a 150 GPD membrane, choose the 150 GPD option from the size selector on this page instead.
• MATCH THE FILTER TO YOUR WATER - Service intervals depend on what is in your supply and how much water you run. Heavy sediment or a well source typically means changing prefilters more often; light municipal use typically stretches the interval. Watch your flow rate and your TDS reading rather than the calendar, and change the prefilters before the membrane pays for it.

This three-piece set is one full service for a Stealth RO100 system: a sediment cartridge, a carbon block cartridge and a 100 GPD reverse osmosis membrane, packed together so one order covers the whole change.

The sediment stage runs first and holds particulate - sand, silt, dirt and rust - before it can reach anything downstream. The carbon block runs second and reduces chlorine along with the tastes and smells that come with it. That second stage does double duty, because chlorine reaching a reverse osmosis membrane shortens its working life, so the prefilters are what protect the most expensive part of the system. The membrane runs last and reduces total dissolved solids.

Membrane output is a matched specification, not a preference. The drain-line flow restrictor on an RO system is sized to the membrane it was built around, so this set is for systems running a 100 GPD element. A 150 GPD version of this set is available from the size selector on this page, along with prefilters on their own and membranes on their own.

Complete Filtration Services has built and supplied replacement filtration since 2006.
