PSI-021-5RM-HA 5-Stage Re-Mineralizing Reverse Osmosis System
Experience ultra-pure, oxygen-rich, and high-alkaline water directly from your tap with the PSI-021-5RM-HA Reverse Osmosis System. Designed for efficiency and superior performance, this 5-stage system features advanced filtration technology and a refillable Hi Alkalizer to enhance water quality and taste.
Key Features
- 5-Stage Filtration – Comprehensive purification process for maximum contaminant removal.
- Re-Mineralizing Hi Alkalizer – Raises water pH to 8.5–9.5, adds beneficial minerals, and oxygenates the water for enhanced taste and health benefits.
- Low Waste Ratio (1:1) – Efficient water usage with exclusive membrane flushing technology.
- High Output – Equipped with a Dow Filmtec 300 L/day TFC membrane, capable of producing up to 450 L/day at higher pressures.
- Compact Under-Sink Installation – Fits neatly under your sink with a dedicated faucet for easy access.
- Pressure Limiting Valve Included – Ensures system safety and longevity.
- NSF Certified Components – Meets Australian Standards for safety and performance.
5-Stage Filtration Process
- Stage 1: Sediment Filter – Removes dirt, sand, and other particulates.
- Stage 2: Carbon Block Filter – Reduces chlorine, chemicals, and odours.
- Stage 3: Dow Filmtec TFC Membrane – Eliminates up to 98% of contaminants, including fluoride, heavy metals, viruses, and bacteria.
- Stage 4: Post Carbon Filter – Enhances taste and removes residual impurities.
- Stage 5: Hi Alkalizer Re-Mineraliser – Adds essential minerals and increases pH for alkaline water.
Hi Alkalizer Re-Mineraliser Details
This unique final stage of the system restores the healthy properties often removed by the reverse osmosis process. The refillable alkaline cartridge is filled with a proprietary blend of mineral media that:
- Increases pH to between 8.5 and 9.5, depending on source water quality and pressure.
- Adds back healthy minerals like calcium, magnesium, and potassium – naturally found in spring water.
- Oxygenates the water by micro-clustering and energising it, giving it a smoother mouthfeel and better absorption.
- Improves taste by neutralising any residual acidity and giving the water a “silky” feel.
- Helps to re-balance electrolytes, which may benefit hydration and support general wellness.
Unlike sealed inline cartridges, this one is fully refillable, making it cost-effective and eco-friendly. Refills are available and recommended every 24 months.
The alkaliser is rated to treat up to 10,000 litres of filtered water before a refill is required. A flow restrictor is installed to ensure optimal contact time and maximum mineral absorption.
