CFS RO Prefilter Set – 10" x 2.5" – Fits FILTER-MAX-ES50, ROES-50, RO-90

RO prefilter set from CFS covering the three prefilter positions of FILTER-MAX-ES50 and ROES-50 systems: one 5 micron sediment filter and two carbon blocks, all standard 10" x 2.5". Available as a complete set with wrench or as the prefilters only.

• Sediment filter goes first, holding back dust, particles, and rust
• Two carbon blocks remove chlorine before it reaches the membrane, protecting its service life
• Standard 10" x 2.5" cartridges
• Change all three about every six months on typical municipal water, sooner on well water
• Membrane and post filter are separate parts — this set covers the three prefilter positions
• Run water through new carbon cartridges for a few minutes before use to clear loose carbon fines
