Why Add an Alkaline Remineralization Filter After Your RO System?
Reverse osmosis is one of the most effective water purification methods available — but it comes with a trade-off. While RO removes contaminants, it also strips out beneficial minerals like calcium and magnesium, leaving water that's pure but slightly acidic and flat-tasting. That's where the NU Aqua Inline Alkaline Remineralization Filter comes in.
The Problem with Pure RO Water
RO-filtered water typically has a pH between 5.5 and 6.5 — slightly acidic. While it's safe to drink, many people prefer water that's pH-balanced and mineral-rich, similar to natural spring water. Pure RO water can also taste flat or hollow compared to mineral water.
How Remineralization Works
The NU Aqua Alkaline Remineralization Filter uses a 5-stage media process to restore what RO removes:
- Bioceramic Media — Activates water molecules and increases oxygen levels for better hydration.
- Tourmaline — Uses far-infrared energy to naturally raise alkalinity.
- Calcite — Boosts pH and neutralizes acidity from dissolved CO₂.
- Maifan Stone — Absorbs residual heavy metals while adding calcium and magnesium.
- ORP Balls — Creates antioxidant-rich water with a negative oxidation-reduction potential.
Key Benefits at a Glance
- Raises pH to an optimal alkaline range of 7.5–9.5
- Restores calcium, magnesium, and trace minerals
- Improves taste — water tastes fresher and more natural
- Universal 1/4" quick connect fittings — works with most RO systems
- Long 5,000-gallon / 8–12 month filter life
Who Should Use It?
This filter is ideal for anyone with an existing RO system who wants the best of both worlds: the purity of reverse osmosis and the health benefits of mineralized, alkaline water. It's also popular for aquariums and hydroponics setups where pH stability matters.
Easy Installation
Install the NU Aqua Alkaline Remineralization Filter as the final stage after your RO membrane and storage tank. The 1/4" quick connect (John Guest style) fittings make installation tool-free in minutes. Compatible with NU Aqua systems and most standard RO configurations.
