Reverse Osmosis Complete Replacement Pre Filters Including RO Membrane

A comprehensive replacement kit for domestic reverse osmosis systems — includes all three pre-filter cartridges plus a replacement RO membrane. Everything required for a complete annual RO system service, in one convenient purchase.

Keeping an RO system performing properly requires regular filter replacement. The pre-filters protect the membrane from sediment and chlorine damage, while the membrane itself gradually loses efficiency over time. Replacing everything together ensures your system is producing the purest possible water.

What's Included:

•     1 × PP Sediment Filter (Stage 1)

•     1 × GAC Granular Activated Carbon Filter (Stage 2)

•     1 × Carbon Block CTO Filter (Stage 3)

•     1 × Replacement RO Membrane

Recommended Replacement Schedule:

•     Pre-filters (stages 1–3): every 6–12 months

•     RO membrane: every 2–3 years (or when TDS output rises noticeably)
