Key Features of the NU Aqua System
1. 7-Stage Filtration Process
This system’s standout feature is its multi-layered filtration process, which purifies, remineralizes, and protects water through seven stages:
- Stages 1–3: Sediment and Carbon Filters: The first three stages target visible particles, chlorine, volatile organic compounds (VOCs), and odors, prepping the water for deeper filtration.
- Stage 4: Reverse Osmosis (RO) Membrane: The RO membrane removes up to 99% of contaminants, including lead, arsenic, heavy metals, and fluoride, delivering ultra-pure water.
- Stage 5: Alkaline Remineralization: This stage adds back essential minerals like calcium, magnesium, and potassium, balancing water pH and enhancing flavor.
- Stage 6: UV Sterilization: A powerful UV filter kills bacteria, viruses, and other pathogens, adding a layer of protection against harmful microorganisms.
- Stage 7: Post-Carbon Filtration: A final carbon filter removes any remaining impurities and polishes the water for a crisp, clean taste.
2. Booster Pump for Consistent Water Flow
The built-in booster pump ensures that water pressure remains consistent throughout the filtration process, making it ideal for homes with low incoming water pressure. This feature helps maintain high water quality and supports efficient system operation, reducing waste.
3. Alkaline Remineralization
The alkaline filter restores essential minerals lost during the RO process and increases the water’s pH level, providing a balanced, mineral-rich drinking experience. Alkaline water is often preferred for its health benefits and refreshing taste.
4. UV Sterilization for Microbial Protection
The UV filter uses ultraviolet light to eliminate microorganisms like bacteria, viruses, and cysts, ensuring an extra level of safety. This feature is crucial for homes concerned with biological contaminants in their water supply.
5. 100 Gallons Per Day Capacity
The NU Aqua system is rated for 100 GPD, which meets the needs of most households, providing ample drinking and cooking water throughout the day without interruptions.
6. Lead-Free Faucet and Storage Tank
Included with the system is a lead-free faucet and a pressurized storage tank, ensuring that purified water is safely stored and dispensed as needed.
Benefits of Using the NU Aqua 7-Stage RO System
Comprehensive Filtration for Health and Safety
With its seven stages of filtration, the NU Aqua system addresses a broad range of water contaminants, including heavy metals, pesticides, bacteria, and viruses. The combination of reverse osmosis, alkaline remineralization, and UV filtration ensures that water is not only safe but also beneficial for health.
Improved Taste and Alkaline Benefits
The system’s alkaline filter enhances water taste by restoring minerals, making it a great option for those who enjoy mineral water. Additionally, the higher pH level associated with alkaline water can be beneficial for hydration and digestion.
Eco-Friendly Alternative to Bottled Water
Using an under-sink RO system reduces the need for bottled water, which not only saves money but also benefits the environment by decreasing plastic waste.
Easy Installation and Maintenance
The NU Aqua 7-Stage system is designed for user-friendly installation with clear instructions and included accessories. Maintenance is straightforward, with each filter typically lasting 6-12 months depending on usage and water quality.
