Excalibur Premium RO System – 6-Stage Reverse Osmosis with Alkaline Remineralization
6-Stage Reverse Osmosis System with Alkaline Remineralization — 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 an alkaline remineralization stage — removing harmful contaminants while adding beneficial minerals back into your water for a naturally balanced, great-tasting result.
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 and low pH corrected by remineralization. Perfect for health-conscious households who want both purity and mineral balance.
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 4 — 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 5 — Carbon Polishing Filter: Post-membrane polish for crisp, clean taste.
- Stage 6 — Alkaline Remineralization Filter: Calcite and GAC media adds calcium, magnesium, and other beneficial minerals back into purified water, raising pH to a naturally balanced level.

Why Remineralization?
Standard RO removes virtually everything — including beneficial minerals — leaving water that can taste flat and have a slightly acidic pH. The Stage 6 alkaline remineralization filter adds calcium, magnesium, and trace minerals back in balanced proportions, improving taste and raising pH without compromising the purity of the RO process.
6-Stage vs. 5-Stage
The Premium RO 6-Stage adds alkaline remineralization for mineral-balanced water. The Superior RO 5-Stage delivers excellent RO purification without remineralization. Choose the 6-Stage if mineral balance and pH matter to you; choose the 5-Stage for straightforward high-output RO.
Replacement Filters & Membrane
Replace filter cartridges every 6–12 months and the RO membrane every 2–3 years. Genuine replacement filters and the 100 GPD membrane are available in our store.
