10 Stage Reverse Osmosis Drinking Water System
RO 10 Stage Under Sink Water System
Pure Water. Refined Experience. Structured Water.
Advanced filtration meets structured water for the ultimate drinking water upgrade.
10 Stage Filtration Reverse Osmosis Remineralization Under Sink System Dedicated FaucetUnder Sink Revitalizer Included
The RO 10 Stage Under Sink Water System is designed to deliver the highest level of drinking water quality—removing contaminants first, then restoring balance and structuring before it reaches your glass.
Reverse osmosis is widely recognized for its ability to remove up to 99% of contaminants including lead, chlorine, fluoride, and more.
This system takes it further by combining multi-stage filtration with remineralization and structured water flow—creating water that is not only clean, but smoother, more balanced, and more enjoyable to drink.
Because water should be both pure and alive with movement.

Science & Filtration
Reverse osmosis uses a semi-permeable membrane to remove contaminants at a molecular level, making it one of the most effective filtration methods available.
Multi-stage systems enhance this process with additional filters and mineral stages to improve both purity and taste.
Installation
Installs under your sink with a dedicated drinking water faucet. Most systems can be installed by homeowners or plumbers.

Who Should Choose Each System:
- Already have a filter or want mineral-rich water? → Under Sink Structured Water System

-
Need both filtration and structuring from scratch? → Under Sink Structured Water System with Filtration or RO 10 Stage System
Why Choose Under-Sink Structured Water?
Under-sink systems deliver structured water directly to your kitchen faucet—ideal for apartments, condos, and homes where whole-house installation isn't practical. These units work passively using flow-inspired vortex technology to support better hydration and taste.
How it's different from whole-home systems:
Whole-home systems structure water at every tap (showers, laundry, appliances). Under-sink units focus on your kitchen tap only—lower cost, simpler installation, ideal if drinking water quality is your priority.
Two Filtration Standards. One Elevated Outcome.
Multipure + Structured Water
The Multipure Aquaversa is our preferred under-sink filter to pair with Natural Action technology. It uses a compressed solid carbon block with a 0.5-micron absolute pore size to deliver high-quality contaminant reduction in a streamlined, efficient system. The Aquaversa is NSF-certified for contaminant reduction, meeting rigorous independent testing standards for chlorine, lead, VOCs, and other drinking water contaminants.
Reverse Osmosis + Structured Water
For those seeking the highest level of purification, our proprietary 10-stage RO system reduces dissolved solids and unwanted impurities, with reverse osmosis membranes typically removing up to 99% of common contaminants including lead, chlorine, fluoride, and arsenic.
Frequently Asked Questions
What is structured water?
Structured water is water that has passed through vortex flow patterns similar to natural streams and springs. Natural Action units use internal flow-form technology to create organized movement, supporting water that feels smoother, hydrates more effectively, and tastes cleaner. It's not about adding or removing anything—it's about restoring natural water dynamics through geometric flow pathways.
Do these units filter my water?
No. Natural Action under sink structured water systems do not filter water or remove contaminants. They structure water through flow dynamics. If you want both filtration and structuring, choose the Under Sink Structured Water System with Filtration bundle (which includes the Multipure Aquaversa filter) or install a Post RO Structured Water System after your existing reverse osmosis system.
What's the difference between the Under Sink Structured Water System and the RO version?
The standard Sink System connects to your cold water line and works with standard ½" plumbing. The RO version (HD-9-RO) uses ¼" quick-connect fittings and installs between your RO tank and faucet. Choose based on whether you have an RO system already installed.
Can I install this myself?
Many customers install under-sink units themselves using standard plumbing connections. The Under Sink Structured Water System includes mounting brackets and connection fittings. Installation typically takes 30-60 minutes. If you're not comfortable with under-sink plumbing, hire a licensed plumber for professional installation.
Will this work with my existing under-sink filter?
Yes. Install the unit after your filter so water is filtered first, then structured before reaching your faucet. This is the recommended setup for customers who want both contaminant removal and structured water benefits.
Do I need electricity or batteries?
No. All Natural Action structured water products are passive systems—no electricity, no batteries, no moving parts. Water flows through the unit and is structured by internal geometry and flow-form design.
How long do these units last?
Natural Action structured water products are designed for long-term use with a 10-year limited warranty. There are no filters to replace, no maintenance schedules, and no consumable parts. Once installed, they work continuously without intervention.
What's included in the Under Sink Structured Water System with Filtration bundle?
This bundle includes the Multipure Aquaversa under-sink carbon block filter (NSF-certified, 0.5-micron contaminant reduction), the Natural Action Under Sink Structured Water System, a dedicated drinking water faucet, and all necessary installation fittings. Water is filtered first (removing chlorine, lead, VOCs, and other contaminants), then structured before reaching your faucet. Filter cartridges need replacement approximately once per year.
Will this remove chlorine, fluoride, or heavy metals?
No. Structured Water products do not remove contaminants. Pair with a filtration system if contaminant removal is your goal. The Multipure Aquaversa (included in our filtration bundle) removes chlorine, lead, and VOCs. Reverse osmosis systems remove fluoride, arsenic, and dissolved solids.
How does this compare to a whole-home system?
Whole-home systems (like the Whole Home Structured Water System or MagnaRay Advanced Structured Water System) install on your main water line and structure water at every tap—showers, laundry, appliances, and drinking water. Under sink units structure water at one tap only (your kitchen sink). Choose under sink if you're focused on drinking water quality, or whole-home if you want structured water throughout your home.
What's the difference between structured water and alkaline water?
Alkaline water has a higher pH (typically 8-10) achieved by adding minerals or through electrolysis. Structured water focuses on molecular organization and flow dynamics, not pH. Some customers use both, but they address different aspects of water quality.
Is structured water scientifically proven?
Structured water research explores how flow dynamics, vortex movement, and material interactions affect water properties. While mainstream scientific consensus is still developing, customer reports consistently describe improved taste, hydration, and overall water experience. Natural Action products are not medical devices and make no health claims.
Can I use this with well water?
Yes, but we recommend filtering well water first. Well water can contain sediment, bacteria, and minerals that should be addressed through filtration before structuring. Pair the structured water system with appropriate filtration for your well water quality.
What if I don't notice a difference?
Natural Action offers a 90-day satisfaction guarantee. Most customers notice smoother mouthfeel, better taste, and improved hydration within the first few weeks. If the system doesn't meet your expectations, return it within 90 days for a full refund.
