Red eyes. Chlorine smell. Faded swimwear. There’s a better way.
The natural swimming pool alternative to chlorine for UK homeowners. Origin Aqua’s Mineral+Biome® replaces chlorine with a self-sustaining mineral system , crystal-clear water with no chemicals, no salt, no UV, and none of the side effects. Used in over 200 UK pools since 2010. One-day retrofit for any existing pool.
Why People Switch to a Chemical-Free Pool
Whether you're searching for a chlorine-free pool, a natural swimming pool, or simply want your water to feel clean rather than chemical , the problem is the same. Chlorine reacts with sweat, sunscreen, and body oils to form chloramines: disinfection byproducts that cause skin rashes, stinging eyes, and respiratory irritation, particularly in indoor pools.
UK health authorities have measured chloramine levels in public pools exceeding occupational exposure limits for workers. Your family swims in it for fun.
What Mineral+Biome® Actually Does
In 2013, Origin Aqua's PhD microbiologists discovered that beneficial bacteria in the mineral substrate remove phosphate, nitrogen, and carbon from the water , the nutrients pathogens need to survive. Starve the water of nutrients and it stays clean without disinfectants. The result is a freshwater pool that maintains itself , closer to a natural swimming pool than any chlorine or salt system can achieve.

Frequently Asked
Can I retrofit my existing pool?
Yes. One-day installation , works for new builds and existing chlorine or salt water pools alike.
What does a chlorine free swimming pool cost to run?
Zero chemicals spend, 50% less electricity, and only two service visits per year. Most pools see payback within 3–5 years.
Is it the same as a natural pool with plants?
No , Mineral+Biome® is a mineral pool system, not a pond. You get the clean water of a natural pool without reeds, planting zones, or wildlife.
Is it safe for children or people with eczema?
Yes , that is one of the main reasons families switch. Mineral+Biome® produces no chloramines, no disinfection byproducts, and no chemical residue on skin. Families with eczema, psoriasis, or sensitive skin report significant improvement. The water is closer to a mineral spring than a conventional pool.
How much maintenance does a chemical-free pool need?
Two scheduled technical service visits per year , that is the entire routine. No daily chemical testing, no weekly shock treatments, no algaecide top-ups. Between visits the microbial ecosystem manages itself.
Is it suitable for an indoor pool?
Mineral+Biome® is particularly suited to indoor pools. Chlorinated indoor pools produce trichloramines , the gas responsible for the sharp smell and respiratory irritation in indoor pool buildings. The system eliminates chloramines entirely, so indoor air quality improves immediately after installation. No additional ventilation upgrades needed.
"We switched from a saltwater pool last year. The difference is immediate , no chemical smell, no red eyes, and we have not touched a chemical since."
