Passive systems require neither electricity nor salt nor magnets
They are particularly suitable for whole-house systems, where the incoming water is purified and treated in such a way as to provide active limescale and corrosion protection throughout the home.
Modular: tailored to your needs
With solutions from SANSEI innovations, the minerals contained in the water are not removed and no substances are added (sodium, E-numbers and acids). Our customers can decide for themselves, on a modular basis, how strong the filtration performance should be. All our systems are free from plastic, rubber, glue, cellulose or chemical additives. SANSEI Innovations uses pure, chemical-resistant stainless steel (316) with a surface roughness of 0.7 microns (surgical steel: 0.5 microns) and purely natural filter materials of the highest purity.
Safety: through external laboratory testing
Each system has been tested by external laboratories throughout the entire recommended lifespan of the materials used, and beyond, for effectiveness in terms of bacterial reduction and filtration performance.
We are very proud that the water from our filter media remains well below the Swiss recommended bacterial limit even after a year of intensive use.
Sustainability: redefined
Our SAN-MAXI stainless steel cartridges with a reservoir are ultrasonically cleaned, disinfected using 100% biodegradable agents and 100% reusable. The filter materials are 100% natural.
We deliberately avoid plastic cartridges, as these exacerbate the global microplastics problem and their surfaces cannot be kept sterile. We also avoid additives such as salt, E-numbers or chemicals, as these would place an additional burden on our environment.
With our SAN-TITAN, we go the extra mile. It is the world’s first filter that does not need to be replaced. Its titanium membrane has a filtration capacity of 0.2 microns and is therefore strong enough to remove the majority of all undissolved substances, including bacteria, microplastics, long-chain PFAS, heavy metals, aluminium and dust. The filter can be backwashed and is cleaned at regular intervals using ultrasound before being reinserted.
Rented flat: is your landlord not on board? Take matters into your own hands!
With the SAN-MINI, you get all the benefits of mains water connection technology in a compact form. You can simply have it fitted to the cold water supply: quick, cost-effective and removable at any time without leaving a trace. This gives you safe water for cooking, for tea, coffee and preparing baby food.
GRANDER®
There are many water revitalisation systems on the market. We recommend GRANDER®, the Austrian pioneer whose system has been most extensively researched and documented. It also integrates seamlessly with products from SANSEI innovations.
