Natural pool filtration, engineered for swimming pools
Mineral+Biome® is a natural pool filter system for conventional pools. A living biofilter, fine filtration, UV and trace minerals keep the water clear and fresh without chlorine, salt or copper.

How the natural pool filter system works
Six stages in one compact system. Select a number on the system, or open a stage below.
-
Glass media in the top chamber of the filter removes suspended particles down to about 3 microns. It polishes the water and protects the biology working below.
Crystal-clear water, without a clarifier.
-
In the chamber below, billions of naturally occurring microbes form a living biofilm. They consume organic matter and the nutrients that algae and bacteria need, and they outcompete unwanted organisms for space and food, while tiny protozoa graze on bacteria, a process known as biological predation.
In laboratory trials a biofilter like this removed up to 99.9% of test bacteria in 24 hours (npj Clean Water, 2022).
Water that stays balanced by itself, day after day.
-
Every system includes UV. As water passes the lamp, ultraviolet light inactivates microorganisms, adding a physical barrier without adding anything to the pool. The bulb is changed once a year.
Layered protection, nothing to dose.
-
A metered doser adds trace amounts of minerals, including zinc, magnesium and selenium. They support the biofilter, help keep algae down and give the water its clean, mineral-balanced feel.
Water that feels closer to an alpine spring than a swimming bath.
-
Algae need phosphate to grow. A light flocculation stage takes phosphate out of the water, targeting below 0.01 mg/L, so algae have nothing to feed on.
No algae. No shock dosing. No green water after a hot week.
-
A touchscreen controller runs backwashing and dosing on its own, and watches flow, pressure, temperature and top-up water around the clock. Owners and installers see it all in the Origin Aqua app.
What goes into the water: no chlorine, no salt, no copper. Just trace minerals and UV. What we mean by chemical-free
The benefits of a Mineral+Biome® pool
Point at a benefit to see what it means for you.
Mineral-balanced water
Trace minerals, including magnesium and selenium, give the water a soft, fresh feel inspired by alpine lakes and thermal springs.
Spring-water feel, in your own pool.
Exceptionally clear
Every chemical added to a pool raises its total dissolved solids (TDS), which dulls the water. With nothing to add, TDS stays low and the water stays pure.
Typical TDS figures, Origin Aqua.
Water you can see the floor through.
Softer on skin, gentler on eyes
No chlorine means no chloramines, the cause of red eyes and the familiar "pool smell". Softer on skin and gentler on eyes than chlorinated water.
No smell on your skin after a swim.
Looks after itself
Automatic backwashing and dosing, with every key reading checked around the clock. Two service visits a year.
No test kits. No weekly chemistry.
Lower running costs
- Up to 70% lower total annual running cost than a chlorine pool
- 50–70% less energy and water than chlorine or salt
- Upgrading an existing pool pays back in 3–7 years, depending on pool type and location
Lower bills, every year.
New build or existing pool
One compact system that fits a new plant room or the one you already have.
- No plumbing changesto an existing pool
- 1–2 daysto install
- Swim the same dayfull balance in 6–8 weeks
- Down to 10 m³plunge pools too
Lighter on the planet
Less energy and less water, and no chlorine to manufacture, ship or store. Backwash water can be collected for the garden.
A pool that asks less of the planet.
Runs itself. Tells you everything.
The controller automates backwashing, dosing and pump speed, and our central server watches every system around the clock. If a reading drifts, you and your installer hear about it first.

Four filters. One for every plant room.
Standard sizes cover pools from plunge pools to 200 m³ indoors, with larger pools designed on request.
