CFS RODI Replacement Filter Kit – 10" – Sediment, Carbon & Color-Indicating DI

Three stage reverse osmosis deionization (RODI) replacement kit from CFS — the three cartridges that take water from the tap toward zero TDS: sediment, carbon, and a color-indicating DI cartridge filled with ResinTech MBD-30 nuclear grade mixed bed resin.

• Sediment cartridge holds back sand, silt, and rust
• Carbon cartridge reduces chlorine taste and odor and keeps chlorine off the membrane
• Color-indicating DI resin polishes last, pulling remaining ions — it changes color as it exhausts so you replace on color, not a calendar
• Standard 10" cartridges
• Change sediment and carbon about every six months depending on your water
• Zero TDS water is ideal for spot-free rinsing, aquariums, and more
