About This

• NINE PIECES, A FULL YEAR OF PREFILTERS - 2 grooved sediment cartridges, 2 carbon block, 2 granular carbon, 2 inline post filters with 1/4 inch quick connect, and 1 reverse osmosis membrane rated 50 GPD. Prefilters change about every six months, so two of each covers a year, and the membrane runs roughly two years.
• UNIVERSAL RO FILTER SYSTEM COMPATIBILITY - Fits most standard under sink reverse osmosis systems using 10 by 2.5 inch cartridges, including RO5MX, ROES-100, ROES-50, RCC100P, RO5e, FLTSET0510Q, MAX90, F5-75, Puroflo ERO 5, RFK-5, CMP10-F, Culligan 1000R, 1000R-D, 750R-D, IC-1000, RV-1000, SY-1000 and Simpure SP4-RO75.
• WHAT EACH STAGE DOES - Sediment goes first and captures sand, silt, dirt and rust. Carbon block and granular carbon reduce chlorine, which matters because chlorine damages the membrane behind them. The membrane does the actual reverse osmosis and reduces total dissolved solids. The inline post filter polishes the taste of stored tank water on its way to the faucet.
• 10 BY 2.5 INCH IS THE INDUSTRY STANDARD SIZE - Most under sink RO systems use it, which is why one kit covers so many brands. Measure a cartridge you are pulling out if you are unsure; the inline post filters use 1/4 inch quick connect, so check yours are push-fit rather than threaded before ordering.
• CHANGE THE CARBON ON TIME AND THE MEMBRANE LASTS - A spent carbon prefilter passes chlorine straight to the membrane, which is the expensive part. Prefilters about every six months, membrane about every two years. This is a compatible replacement set made by CFS, not an original manufacturer part, and model numbers are used for reference only.
