CFS RO Filter Set with 50 GPD Membrane – Fits WP500024, WP-4V, WP5-50

RO replacement filter set from CFS for WP-4V and WP5-50 five stage systems. The prefilters and the 50 GPD membrane in one box — on most systems, the annual service. Options range from individual pieces to the complete 5-piece set.

• Sediment filter goes first, holding back sand, silt, and rust
• Carbon stage takes chlorine out before it reaches the membrane, protecting its service life
• 50 GPD membrane strips dissolved solids last — standard 1812 element
• Drop-in cartridges are standard 10" x 2.5"
• A 50 GPD membrane pairs with roughly a 500 ml drain line flow restrictor
• Change prefilters about every six months, the membrane every one to two years

Compatible with: WP500024, WP-4V, WP5-50
