For years, the quality of our tap water was a constant concern, leaving a lingering metallic taste and an unpleasant odor that made simply pouring a glass of water feel like a chore. The thought of consuming impurities daily weighed on my mind, especially for my family. I knew this problem needed a solution; otherwise, we’d continue to rely on expensive bottled water, contributing to plastic waste, or worse, compromise our health with what came out of the faucet. Investing in a high-quality water purification system, such as the NU Aqua 7-Stage (12 Step Filtration) UV & Alkaline Under Sink Reverse Osmosis Water Filter System, would have made an immense difference in those early days.
Essential Considerations Before Investing in a Water Filtration System
The quest for pure, great-tasting water often begins when you realize your tap water just isn’t cutting it. Whether it’s the taste of chlorine, concerns about heavy metals, or the desire for truly healthy drinking water, a sophisticated filtration system can be a game-changer. An ideal customer for a premium reverse osmosis water filter system is someone who prioritizes their family’s health, is tired of lugging heavy water bottles, and is looking for a long-term, cost-effective solution for pristine drinking water directly from their tap. This includes health-conscious individuals, families with young children, and anyone living in an area with questionable municipal water quality.
However, if you’re on a very tight budget and only need basic sediment removal for a specific appliance, a full-fledged multi-stage RO system might be overkill; a simpler filter might suffice. But for comprehensive purification, the investment in a system like the NU Aqua is well worth it. Before buying, consider your water quality concerns (chlorine, lead, fluoride, bacteria?), the installation space available under your sink (product dimensions are 15″L x 5.5″W x 19.5″H), the desired flow rate, and the ongoing cost and availability of replacement filters. Also, think about whether you need features like UV sterilization and alkaline remineralization, which significantly enhance water quality beyond basic filtration.

Deep Dive into Performance: Features and Advantages
Having lived with this system for a significant period, I can confidently say that the NU Aqua 7-Stage RO System lives up to its promise. Let’s delve into its features and the tangible benefits they provide.
Advanced 7-Stage (12 Step) Filtration & HydraCoil Membrane
The heart of this system is its comprehensive filtration process. It’s not just 7 stages; it’s a 12-step filtration journey that water undergoes. This includes sediment filters, activated carbon filters, the HydraCoil RO membrane, and finally, the UV and alkaline remineralization stages. From a practical standpoint, this means my water goes from having an initial TDS (Total Dissolved Solids) reading of around 250-444 PPM (depending on municipal water quality variations) down to an astonishing 29 PPM, and sometimes even lower, around 15 PPM after the RO membrane. This level of purity is immediately noticeable. The water tastes incredibly clean, light, and refreshing – reminiscent of pristine spring water. The rigorous development and testing NU Aqua mentions are clearly evident in the consistent, high-quality output. The double o-ring sealed filter housings give me peace of mind against leaks, which is crucial for an under-sink installation. The multi-stage approach ensures that virtually all common pollutants – including arsenic, chlorine, fluoride, lead, and countless others – are effectively removed, offering a purity that far surpasses bottled water.
Superior UV Water Filtration
One of the standout features is the **UV sterilization stage**. Many standard RO systems stop at membrane filtration, but the NU Aqua goes a step further by incorporating a powerful ultraviolet light. This is incredibly important because while RO membranes are excellent at removing physical contaminants, some microscopic bacteria and viruses *could* potentially pass through. The UV lamp acts as a final, critical barrier, effectively neutralizing 99.9% of harmful microorganisms without adding any chemicals. For me, this translates to absolute confidence in the safety of our drinking water. Especially when considering potential fluctuations in municipal water quality or for households with vulnerable individuals, this UV filtration stage provides an invaluable layer of protection, ensuring the water is not just clean but truly sterile.
Alkaline Remineralization
After the intensive purification of the RO membrane, water can sometimes become slightly acidic and stripped of beneficial minerals. The NU Aqua system intelligently addresses this with its **alkaline remineralization stage**. This post-filter reintroduces essential healthy minerals back into the water, such as calcium and magnesium, while simultaneously raising its pH to a more alkaline level. The benefit here is twofold: improved taste and enhanced health benefits. The water tastes smoother and more palatable, without the slightly “flat” taste that some pure RO water can have. From a health perspective, many people believe that consuming alkaline water can help balance the body’s pH, and while scientific evidence on the direct health benefits is debated, the reintroduction of minerals is definitely a positive. It ensures that the water isn’t just pure, but also nutritionally balanced and great-tasting. This alkaline water filter stage elevates the system beyond basic purification, delivering water that feels truly premium.
100 GPD High Flow Rate
The **100 GPD (Gallons Per Day) flow rate** is a significant advantage that dramatically improves the user experience. My previous system felt like it took ages to fill a pitcher or a pot for cooking. With the NU Aqua, the storage tank fills up remarkably fast – sometimes twice as quickly as older, lower GPD systems. This means fresh, purified water is always readily available. There’s no more waiting around, which is incredibly convenient for a busy household. Whether I’m filling a large pot for pasta, making coffee, or simply getting a glass of drinking water, the flow from the dedicated faucet is consistent and strong enough for everyday needs. While it’s not the same pressure as a regular tap, it’s more than adequate for drinking and cooking purposes. This high flow rate translates directly into less frustration and more on-demand access to clean water, which is a major convenience for any busy kitchen. This 100 GPD RO filtration capability truly sets it apart from many competitors.
Easy Installation & Bonus PPM Meter
The installation process was surprisingly straightforward. The system comes largely pre-assembled, reducing the complexity. The inclusion of a clear, user-friendly manual with pictures, along with color-coded tubing and quick-connect fittings, made the process much less daunting than anticipated. It genuinely took less than an hour, with most of that time spent carefully following the instructions and ensuring secure connections. While some users mentioned minor issues with specific fittings or the need to replace some tubing for extra security, I found my experience smooth sailing. The system’s compact dimensions (15″L x 5.5″W x 19.5″H) also meant it fit perfectly under my standard kitchen sink, leaving ample space for other items.
The **bonus PPM meter** is a fantastic addition. It allows me to instantly verify the water quality and see the dramatic difference between tap water and the purified water. This transparency builds trust in the system’s performance and is a great tool for monitoring when filter changes might be necessary. Observing my tap water at 444 PPM drop to a mere 29 PPM (or even lower) after filtration is incredibly satisfying and provides objective proof of the system’s efficacy.
Premium Quality & Thoughtful Design
From the elegant NSF 100% lead-free designer stainless steel countertop faucet to the professional-grade quick-connect fittings and double o-ring sealed filter housings, the build quality of the NU Aqua system is impressive. It feels sturdy and well-engineered. The inclusion of a leak detector is a critical safety feature, providing peace of mind against potential water damage under the sink. This attention to detail extends to the filters themselves, with carbon filters boasting a higher absorption rate due to their molecular structure, ensuring even the smallest particulates are removed. The 120-day home trial and 3-year warranty, backed by lifetime support, further underscore NU Aqua’s confidence in their product and commitment to customer satisfaction. This comprehensive approach means not only am I getting superior water, but I’m also investing in a reliable product with excellent post-purchase support.
Disadvantages to Consider
While my experience has been overwhelmingly positive, a few minor points are worth noting. As mentioned, the **flow rate from the dedicated faucet**, while sufficient, isn’t as robust as a direct tap connection. For those accustomed to very high pressure or needing to fill exceptionally large containers rapidly, this might be a slight adjustment. However, NU Aqua does offer pump versions for those requiring enhanced pressure. Secondly, during installation, a few users (and myself, briefly) found that some of the initial quick-connect fittings, particularly around the UV sanitizer, required extra attention or even replacement with higher-quality ones to prevent minor leaks when the system pressurized. While easily remedied, it’s an extra step some might encounter. Finally, one user noted that the metal bracket holding the filter housings isn’t reversible. While a minor aesthetic point, for those with specific under-sink layouts or wanting the clear sediment filter visible, this could be a slight design limitation. These are small concerns, however, overshadowed by the overall exceptional performance and quality of the system.
Community Insights: Real-World User Feedback
After scouring various online platforms, it’s clear that the general sentiment surrounding the NU Aqua 7-Stage UV & Alkaline Under Sink Reverse Osmosis Water Filter System is overwhelmingly positive.
