How does natural pool filtration work?

Natural pool filtration uses a five-stage biological and physical process to clean water without chemicals. Beneficial microorganisms outcompete and consume harmful pathogens through biological predation. Combined with ultra-fine filtration to 3 microns, UV treatment, active mineralisation, and phosphate extraction, the system produces water that exceeds EU bathing water standards with no chlorine, salt, or pH chemicals.

What is a biofilter pool system?

A biofilter pool system uses colonies of beneficial microbes housed within a purpose-built filtration unit to eliminate pathogens biologically. Origin Aqua's Mineral+Biome® is the only UK-developed, fully-patented biofilter pool system with peer-reviewed scientific evidence of 99.9% pathogen elimination, published in Nature Water.

Is natural pool filtration safe — does it actually eliminate bacteria?

Yes. Independent scientific testing of Mineral+Biome® demonstrated 99.9% elimination of common pool pathogens using beneficial biology alone, with no disinfection chemicals. This was peer-reviewed and published in Nature Water, establishing it as the only pool filtration technology with published scientific evidence of pathogen elimination through biological means.

What is the difference between a natural pool filter system and a chlorine pool?

Chlorine pools use chemical disinfection that produces chloramines — causing skin irritation, red eyes, and respiratory problems. Mineral+Biome® replaces chlorine entirely with biological predation, ultra-fine filtration, UV treatment, and mineralisation. The water is softer, odour-free, and exceeds EU bathing water standards without any disinfection chemicals.

Which universities have researched Mineral+Biome natural pool filtration?

Origin Aqua conducted R&D partnerships with Cranfield University and the University of the West of England (UWE) over ten years of development. This independent research contributed to the peer-reviewed paper published in Nature Water confirming 99.9% pathogen elimination using biological filtration alone.

Can an existing chlorine pool be converted to natural pool filtration?

Yes. Mineral+Biome® can be retrofitted to most existing pool installations, replacing conventional filtration and chemical dosing equipment. Origin Aqua's network of approved UK pool builders can assess any existing pool and specify the correct system configuration.

How is Mineral+Biome different from salt water or other mineral pool systems?

Salt water pools still produce chlorine — they generate it on-site via electrolysis. Generic mineral systems add minerals but rely on chemicals for disinfection. Mineral+Biome® eliminates disinfection chemicals entirely using peer-reviewed biological filtration. It is the only natural pool system protected by patents in the UK, EU, USA, and Canada, and the only one with a proprietary IoT monitoring and control system.

How does Origin Aqua Mineral and Biome System work

Step 1 - Fine filtration

Removes suspended particles down to 3 microns

Steps on How mineral pool water filtration works

Step 2 - Bio filtration

Beneficial microbes remove nutrients and pathogens

Step 3 - UV filtration

kills off any remaining pathogens

Step 4 - Mineralise water

With trace elements, such as selenium & magnesium to replicate thermal spa water

Step 5 - Absorbent filtration

Removes remaining phosphorous for ongoing maintenance

The mineral+biome® water quality and swimming experience like no other.

Goodbye Phosphorus.

The good bacteria essentially starve the water of key food sources like phosphorous, a building block of algae DNA, creating a stressful and inhospitable environment for pathogens to survive or multiply.

This allows us to produce heated mineral quality pool water, that far exceeds EU bathing water standards without the need for disinfection chemicals like chlorine.

Meanwhile, our unique mineraliser technology works to condition your pool with thermal spa minerals such as magnesium and selenium which have proven benefits for your health and skin biome.

Hello crystal-clear water.

In a traditional system, everything you add to the water (including chlorine, shock treatments, pH balancers) increases total dissolved solids (TDS), which reduces water clarity.

In our system there are no such chemical reactions;

TDS - Typical chemical pool - 800-1200ppm
TDS - Evian mineral water- 330ppm
TDS - Typical Origin Aqua pool - 250- 500ppm

10 Years of R&D. Peer-Reviewed by Nature Water.

Mineral+Biome® is the result of a decade of dedicated research and development, conducted in partnership with Cranfield University and the University of the West of England — two of the UK's leading institutions in water science and environmental engineering. Thousands of man hours were invested in understanding, testing, and perfecting the biological and mineral processes that make chemical-free pool water possible at scale.

That research produced a single, measurable outcome: 99.9% elimination of common pool pathogens using beneficial biology alone — no chlorine, no salt, no synthetic chemicals of any kind. The finding was independently validated, peer-reviewed, and published in Nature Water, one of the world's most authoritative scientific journals.

Mineral+Biome® is also protected by patents in the UK, EU, USA, and Canada — the formal record of original invention. It is the only pool filtration technology developed through university-backed scientific research and proven to this standard.

Monitoring & Control: Autonomous, App-Connected

Mineral+Biome® includes a proprietary monitoring and control system that automates pool management entirely. Pool owners access their system through a dedicated app — tracking water quality, system performance, and receiving alerts remotely, without manual water testing.

The system runs autonomously. It adjusts filtration cycles, monitors biological activity, and alerts the owner or installer the moment any parameter moves outside its optimal range. No chemistry kits, no weekly testing routines, no guesswork.

This proprietary control and monitoring system is exclusive to the full Mineral+Biome® package supplied by Origin Aqua. It is not available in any licensed or partial version of the technology.
