Drinking water comes into contact with the materials in a filtration system every day. So one thing was clear to us from the outset: We wanted to use as little plastic as possible inside the SAN-MAXI – and none at all in the actual filter area.
The SAN-MAXI housing and the complete filter cartridge are made from 2 mm thick, acid-resistant 316 stainless steel. Both components are hand-welded and designed for a long service life.
No plastic. No seals. No adhesive in the filter area.
Inside the SAN-MAXI, no plastics, seals or adhesives come into contact with the water being filtered.
This not only reduces the use of plastic, but also follows a simple principle: We want to reduce unwanted substances in the water – not create new routes for contamination through unnecessary materials.
316 stainless steel – made for long-term contact with water
316 stainless steel is used wherever corrosion resistance, hygiene and high mechanical strength are required. That is why the material is used for both the filter housing and the reusable filter cartridge in the SAN-MAXI.
The internal surfaces are finished to a surface roughness of around 0.7 µm . The very smooth surface makes deposits less likely and makes cleaning easier.
Built to last.
While many filtration systems require complete plastic housings or filter inserts to be replaced regularly, the stainless steel cartridge in the SAN-MAXI is designed for a very long service life .
When the cartridge is replaced, it is not thrown away: it returns to our circular system, where it is refurbished and reused. Only the used filter materials are replaced.
This is how we combine durable materials with a filtration system that is not designed as a disposable product.
Less plastic. Less waste. Better hygiene.
