DESCRIPTION
The everyday workhorse of the Natural Action lineup.
The Natural Action Standard Size Structured Water Unit installs right on the main line coming into your home, so every faucet, shower, and appliance gets Natural Action's structured water.
No electricity. No salt. No filters. No maintenance. Ever.
Not a filter, so pair it with filtration if you have contaminants to remove.
Set it once. Forget it forever.
HOW TO USE
- Find your main water line where it enters the house.
- Shut off the water and install the unit inline. It's bi-directional, so either way works.
- Turn the water back on and check for leaks.
- Done. Nothing to replace, refill, or plug in.
HOW DOES IT WORK
Water entering your home flows through the unit's internal flow form, which spins it through multiple vortexes, mimicking the way water moves in nature.
Natural Action says this process "structures" the water, which they describe as giving it a smoother feel and helping with scale, without salt or chemicals and without removing minerals.
From that point on, every pipe, water heater, and tap in the house gets the treated water.
What Owners Say
Installation is consistently described as quick — most reviewers report finishing setup themselves in a few minutes, with the difference in shower feel noticeable right away. Several customers with two units (one between the showerhead and spout, one built into a replacement showerhead) reported both delivering a similarly softer, more pleasant experience, especially noticeable by comparison after staying somewhere with harder water. A few reviewers mentioned using the unit for houseplants and pets as well, reporting healthier growth and coat condition.
One reviewer described the device as preventing chlorine absorption into skin — this is an individual customer's characterization, not a verified or clinically established claim; see the disclaimer in Block 10. A couple of reviewers also flagged longer-than-expected shipping times, though customer service was consistently praised for responsive order tracking help.

The Manufacturer-Claimed Benefits
- Softer Skin and Hair — the brand states that increased absorption from structured water results in softer-feeling water and less irritating effects from chlorine while drinking and showering
- Reduction in Scale — the brand states that changing the structure of water also changes the structure of dissolved substances into forms more easily broken up and carried away, meaning less deposit buildup in showerheads, water heaters, pools, dishwashers, glassware, valves, filters, and pipes
- Increased Cellular Function — the brand states structured water can more effectively pick up, surround, and isolate toxins, aiding the body's natural elimination process while delivering nutrients and energy
- Increased Oxygen — the brand states increased oxygen in the water passively oxidizes chemicals while providing additional oxygen and hydrogen for hydration
