About This

• EVERYTHING FOR A FULL CHANGE - One sediment cartridge, one carbon cartridge, one color indicating DI cartridge and one 100 GPD membrane, for standard 10 by 2.5 inch slim line RODI systems. Four stages in one order rather than tracking down each part separately.
• FOUR STAGES IN ORDER - Sediment first, to hold back the sand and rust that would blind the stages behind it. Carbon second, and that stage is doing double duty: it takes chlorine out before the water reaches the membrane, which is the single thing that shortens membrane life fastest. The 100 GPD membrane reduces dissolved solids third. Color change DI resin polishes last, pulling the ions the membrane let through.
• LOW TDS FROM EVERY SOURCE - On municipal tap or private well supply, the membrane reduces dissolved solids and the DI stage finishes the job, giving low TDS water 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.
• THE DI RESIN TELLS YOU WHEN IT IS DONE - The DI is color indicating, so it changes shade as it exhausts and you replace it when the color turns rather than on a calendar. The other three stages are on time: sediment and carbon about every 6 months, the membrane about once a year. Because this kit is rated at 100 GPD, check that your drain line flow restrictor is sized to match; a restrictor meant for 50 GPD will hold the output back.
• MATCH THE FILTER TO YOUR WATER - Cartridges are maintenance parts, not water treatment plans, and no single one handles everything. Carbon reduces chlorine taste and odor. Sediment media captures sand, silt, dirt and rust. For any specific contaminant you are concerned about, look for a system certified to the NSF/ANSI standard that names it. If you are on a private well, start with a water test.
