TL;DR
Most water-filter conversations begin and end with contamination: chlorine, sediment, heavy metals, PFAS, microplastics and everything else we would rather not drink. That matters enormously—but I believe it is only half the conversation.
After more than 26 years working with drinking water, I have learned to ask a second question: once the unwanted substances have been reduced, what sort of water is left?
Is it stripped of its natural minerals? Does it taste pleasant enough that people will actually drink it? Can it help a household abandon single-use bottled water? And could water have physical qualities that conventional chemical testing does not fully describe?
My conclusion is simple: good drinking water should not merely be less contaminated. It should be water we enjoy, trust and choose every day.
Water Connects Everything
For many years, I have been interested in the idea of oneness—the recognition that we are not truly separate from one another or from the natural world.
Water makes that idea very practical.
The water in our bodies is not somehow disconnected from the water in our rivers, rain, soil and oceans. We take water in, use it and return it to the wider environment. The health of the Earth and our own health are not two separate subjects. They are parts of the same conversation.
That is why the great accumulations of plastic in our oceans are more than an ugly environmental problem. They are a mirror. For decades, humanity has treated plastic as though it disappears when it leaves our hands. Now we know that it breaks down, moves through waterways and food chains, and returns to us as microplastics.
We filled the environment with plastic first. Now researchers are finding plastic particles throughout the human environment—and in samples taken from the human body.
It is difficult to imagine a clearer demonstration of interconnection.
Recycling Is Helpful—but Reduction Is Better
Most of us grew up with the familiar phrase:
Reduce. Reuse. Recycle.
Yet we often behave as if recycling were the first and most important option. It is actually the last.
Recycling has a useful role, but it does not remove the original demand for plastic. It does not guarantee that every bottle will be collected, successfully processed and turned into something useful. Nor does it prevent the energy use, transport and waste involved in manufacturing the bottle in the first place.
The most powerful step is still the first one: reduce.
For drinking water, that means making the water in our own homes so good that buying water in disposable plastic bottles becomes unnecessary.
This has been part of AlkaWay’s purpose from the beginning. A good home water system should do more than improve a laboratory result. It should change behaviour. It should make the household tap the natural first choice.
When people genuinely prefer their filtered water, the plastic bottle begins to lose its appeal.
The Question Most Water Filters Answer
Conventional filtration usually begins with a sensible question:
What is in my water that I do not want?
Depending on the water supply and the filter technology, the answer may include chlorine, unpleasant tastes and odours, sediment, some metals, agricultural chemicals, PFAS, microplastics, fluoride or other contaminants.
This is the chemistry of filtration: identifying particular substances and reducing them with an appropriate technology.
It is essential work. At AlkaWay, we have spent more than 26 years studying filtration media, water conditions and the difference between persuasive marketing and meaningful performance.
But removing unwanted substances raises another question—and this is the question that is too often left out:
What kind of water remains?
Purity Isn’t the Whole Story
It is easy to assume that the purest possible water must automatically be the best possible drinking water.
That assumption deserves closer examination.
Reverse osmosis can be extremely useful when the source water contains dissolved substances that genuinely require membrane separation. It is also valuable in laboratories, manufacturing and other applications that require highly purified water.
But a process designed to remove a very broad range of dissolved material also removes naturally occurring minerals. It may produce wastewater, require storage and maintenance, and leave the user with water that many people find flat unless it is remineralised.
This does not make reverse osmosis “bad.” It means the technology should be matched to the actual water problem rather than automatically treated as the ideal solution for every household.
For ordinary drinking water, I believe the better question is not, “How can we remove absolutely everything?” It is:
How can we reduce the things we do not want while preserving—or restoring—the qualities that make water pleasant and appropriate to drink?
That shift matters.
From Filtered Water to Better Water
Water is not merely a neutral carrier into which contaminants happen to fall. Its mineral content, pH, dissolved gases, temperature and physical behaviour all affect how it tastes and how we experience it.
This is where my own thinking has moved beyond the standard filter sales conversation.
A basic filter is judged mostly by subtraction. A more complete drinking-water system should also be judged by the final water it creates.
I look for water that:
- has relevant contaminants meaningfully reduced;
- retains or receives useful minerals rather than being needlessly stripped;
- tastes fresh and appealing;
- is convenient enough to replace bottled water in daily life;
- does not create excessive wastewater; and
- can be produced without turning filter replacement into another unnecessary waste stream.
This is the philosophy behind our AlkaWay approach and, in particular, the UltraStream. It was designed not simply to remove selected unwanted substances, but to create mineralised, alkaline drinking water containing dissolved molecular hydrogen—all from a compact benchtop system and without the wastewater associated with reverse osmosis.
No single system is the right answer for every possible water supply. But for many households, improving the water rather than completely stripping it is a far more sensible starting point.
What Do People Mean by “Structured Water”?
This is where the conversation becomes more exploratory.
The term structured water is used in several different ways. Sometimes it refers to the temporary organisation of water molecules near surfaces or dissolved substances—something that is genuinely studied in physical chemistry. In the wellness world, however, the same term is also used for claims about vortexing, flow forms, electromagnetic influences and long-lasting energetic “imprints.” Those larger claims are much more debated and are not all supported to the same standard.
I remain open-minded about water. I do not believe our present understanding is the final word on something so fundamental to life. Researchers such as Gerald Pollack, and earlier observers of natural flow such as Viktor Schauberger, have encouraged many people to look beyond a purely mechanical view of water.
At the same time, curiosity is strongest when it is paired with honesty. We should distinguish what has been reliably measured from what is still a hypothesis, an observation or a personal experience.
For me, the useful insight is not that every claim carrying the words “structured water” must be accepted. It is that water quality may deserve a wider lens than contaminant removal alone.
Minerals can be measured. pH can be measured. Dissolved molecular hydrogen can be measured. Contaminant reduction can be tested. Taste and convenience can be experienced. These give us a solid place to begin while the more speculative questions continue to be explored.
Fear Should Not Be the Only Reason We Filter Water
Much water marketing is based on fear.
There is always another contaminant to worry about, another alarming headline or another reason to believe that our water is unsafe. Some concerns are very real and deserve action. But fear alone does not necessarily help us choose the right solution.
When fear takes over, people can be persuaded that the answer is to remove everything—whether or not everything needs to be removed.
I prefer a more constructive approach:
- Understand the source water.
- Identify the genuine problems.
- Choose technology suited to those problems.
- Consider the quality of the finished drinking water.
- Make the result enjoyable and convenient enough to use every day.
This replaces vague anxiety with an informed decision.
The Best System Is the One That Ends the Bottle Habit
A filter can look impressive on a specification sheet and still fail in the real world.
If the water tastes unappealing, the flow is painfully slow, the system wastes too much water or the maintenance is too complicated, people may quietly return to bottled water.
That is why usability is not a minor detail. It is part of the environmental result.
The most effective home system is one that people are happy to use for drinking, cooking and filling a reusable bottle before leaving the house. Each refill is a small act, but repeated across a family and over many years it can prevent a remarkable number of disposable bottles from being bought.
This is where personal wellbeing and environmental care meet. We do not have to choose one or the other. The same decision can support both.
Clean Water Is the Beginning, Not the Destination
After more than 26 years in this field, I no longer see water filtration as a simple contest to produce the emptiest water.
Of course we want to reduce substances that do not belong in our drinking water. But I also want us to think about minerals, taste, molecular hydrogen, waste, convenience and our relationship with the water we drink.
And I want us to remain curious.
Water is involved in every living process. It shapes our bodies, our food, our landscapes and our climate. To treat it merely as a chemical liquid that carries contaminants seems to me far too narrow.
Perhaps the missing half of the water conversation is not one particular device or theory. Perhaps it is the willingness to stop asking only what can be removed and begin asking:
What qualities should good drinking water have?
That is the question that has guided our work at AlkaWay—and it remains the question worth asking.
