The 5 Best Structured Water Devices for Home, Shower, Sink, Travel and Pool
Structured water devices are one of the simplest upgrades you can make to the water you drink, cook with, and shower in every day. If you're exploring ways to build a healthier home, structured water has probably caught your attention.

As a contractor and Building Biologist, I strongly advocate for healthy, structured water, and Natural Action is the brand I recommend. Below are the five Natural Action devices we recommend most, from a whole-home unit on your main water line to a portable pitcher-style unit you can take anywhere.
What Is Structured Water?
Structured water devices are designed to recreate the way water moves in nature, spiraling and vortexing through streams and rivers. Water flows through a passive chamber shaped to set up that vortex motion.
Natural Action devices use vortex flow (the MagnaRay adds a magnetic core). They need no electricity, no chemicals, and no replacement cartridges on the structuring side. People who use them most often describe the water as smoother, softer, and easier to drink.
One thing to know up front: a structuring device is not a filter. It changes how water moves, not what is in it. If your water has contaminants, pair structuring with filtration (our number three pick does both).
When you choose a filter, the CDC recommends looking for an NSF certification on the filter's label to see what it will remove, and it notes that filters cannot remove every type of harmful substance. Testing your water first tells you what you actually need to remove. Our guides to whole house water filtration and water filtration methods walk through the options.
How We Chose These Five
We picked one device for each way people use water at home: the whole house, the shower, the kitchen sink, on the go, and the pool. Every pick is made in the USA, needs no electricity, and carries Natural Action's 10-year limited warranty and 90-day satisfaction guarantee.
The 5 Best Structured Water Devices
1. Whole Home Structured Water System HD-24
The HD-24 is the one to get if you want structured water at every faucet, shower, and appliance in the house. It installs once on your main water line and serves the whole home from that single point.
- Price: $1,499
- Pipe sizes: 3/4" or 1" NPT
- Installation: inline at the main water entry, by a plumber
- Maintenance: none, no filters or cartridges
- Best for: new builds, remodels, and anyone who wants the whole house covered
For larger homes (2,500 square feet and up), hard water above 300 ppm, or heavy water use, Natural Action recommends stepping up to the MagnaRay Advanced Structured Water System ($2,999), which adds a magnetic core for scale reduction.
For context, the U.S. Geological Survey classifies water with more than 180 mg/L of hardness as very hard, and for water 1 mg/L is about 1 ppm, so 300 ppm is well into that range.
When hard water is heated, such as in a home water heater, solid deposits of calcium carbonate can form. This scale can reduce the life of equipment, raise the costs of heating the water, lower the efficiency of electric water heaters, and clog pipes.

3. Under Sink Structured Water System with Filtration
The under-sink system gives you filtered and structured drinking water from one dedicated faucet. Water runs first through a Multipure Aquaversa carbon block filter (0.5 micron), then through the structuring unit, then out the faucet.
- Price: $1,099
- Includes: Multipure Aquaversa filter, Natural Action under-sink structuring unit, dedicated faucet, and install kit
- Filter replacement: about once a year for a family of four ($95 CB6 filter)
- Installation: under the kitchen sink, cold line only
- Best for: drinking and cooking water, especially if you want contaminants filtered out
If you want this at the sink and the whole house structured too, Natural Action also bundles it with the HD-24 as the Whole Home Structured Water System with Under Sink Filtration ($1,999).

- Price: $279
- Size: 7.5" x 3", 9.5 oz
- Materials: food-grade HDPE interior, ABS exterior
- Installation: none
- Best for: travel, the office, dorms, and trying structured water before a bigger install

5. Pool Structured Water System
The pool unit installs inline with your pool plumbing, after the pump and before the return lines, so the water passes through it each time it circulates. Owners describe the water as smoother and more comfortable to swim in. It works alongside your pool chemistry; it does not replace it.
- Price: $2,400
- Installation: inline with existing pool plumbing
- Power: none, fully passive
- Best for: pool owners who swim often and want a more natural-feeling pool

Structured Water Device FAQ
What is the best whole house structured water unit?
For most homes, the Natural Action Whole Home HD-24 on the main water line. For homes over 2,500 square feet or with hard water, the MagnaRay Advanced system.
Do structured water devices filter water?
No. Structuring changes how water moves, not what is in it. For filtered water, choose the Under Sink System with Filtration or add filtration to your whole-home system.
Can you buy structured water?
You can buy bottled structured water, but a portable or whole-home device structures your own water on demand with no bottles and no ongoing cost.
Do I need a plumber to install a structured water device?
For the whole-home and pool units, yes. The shower unit and portable unit need no tools. The under-sink system installs under the kitchen sink and may need a small hole drilled for its faucet.
Do structured water devices need electricity or maintenance?
No. Natural Action structuring units are passive, with no power and no cartridges. The only recurring cost is the carbon filter on the under-sink system, about once a year.
