6-Stage Reverse Osmosis System with Carbon Polish — Pure, Mineral-Balanced Water
The Excalibur Premium RO System 6-Stage is the most advanced under-counter RO system in the Excalibur lineup. It combines high-performance reverse osmosis purification with a carbon polish filter — removing harmful contaminants while enhancing taste. Excalibur SKU EWR 5100C
Who It's For
The Premium RO 6-Stage is ideal for homeowners who want the highest quality drinking water — pure RO water with the flat taste.
How It Works — 6 Stages
- Stage 1 — Sediment Filter: Removes dirt, rust, sand, and suspended particles.
- Stage 2 — Carbon Block Filter: Removes chlorine, chloramines, and VOCs to protect the membrane.
- Stage 3 — Carbon Block Filter: Second carbon stage for thorough pre-membrane chemical removal.
- Stage 3 — RO Booster Pump (80-100psi) for consistent water pressure
-
Stage 5 — RO Membrane (100 GPD): High-output thin-film composite membrane removes up to 99% of dissolved contaminants including lead, arsenic, nitrates, fluoride, and TDS.
-
Stage 6 — Carbon Polishing Filter: Post-membrane polish for crisp, clean taste.
For optional Stage 7 with Re-mineralizing filter, see EWR 5100E
