Swiss-engineered filter system
How the eco-pool system keeps water crystal-clear using natural microorganisms, 40 watts of energy, and 30 years of Swiss engineering refinement.
The core principle
Conventional pools maintain water quality by killing organic matter. Chlorine and chemical disinfectants destroy algae and bacteria, leaving residue, odour, and continuous chemical maintenance.
The eco-pool system inverts this. Instead of killing what grows, it removes what feeds it. Natural microorganisms inside the S1-Filter break down dissolved nutrients — especially phosphorus — continuously. Without nutrients, algae and bacteria cannot establish.
The same mechanism that keeps a river clear. Scaled, engineered, and executed pressureless.
Filtration architecture
Every model — Badebrunnen, eco-pool, Hotelpool — uses the same filtration core, built on four architectural principles that define the system from the inside out.
The filter operates without high-pressure pumps. Lower energy, lower noise, and significantly lower wear than conventional systems.
Microorganisms break down dissolved organic matter naturally. No chlorine, no algaecides, no UV lamps. The water never receives a chemical input.
The filter volume scales with bather load — sized from compact residential pools through to commercial hospitality installations.
Runs 24 hours a day on 40 watts. The system is always active, never reset. Water quality is held steady, not chemically restored.
30 years of research
The eco-pool system is the product of three decades of biological filtration research and Swiss engineering. We collaborate with ZHAW (Zürich University of Applied Sciences) and the ASC on continuous refinement of the technology.
Your next step
Use the configurator to choose your model, size, and finish. Every eco-pool uses the same biological filtration — the difference is which form factor fits your space.
