Water filter against legionella and bacterial infestation in drinking water systems
Acquaspar offers an innovative, self-cleaning ultrafiltration-based Legionella filter—a highly effective solution for microbiological drinking water purification, entirely free of chemicals.
Our advanced membrane filtration technology reliably removes Legionella, E. coli, Pseudomonas, parasites, viruses, and other microorganisms larger than 0.03 µm, with a retention rate of nearly 100%. The Acquaspar ultrafiltration system is a trusted hygiene standard in demanding environments.
The filtration process is purely mechanical: untreated water flows through a high-performance porous membrane that physically blocks pathogens and particles. An integrated rinsing function allows the system to self-clean automatically, discharging the rinse water directly into the drain. Maintenance is minimal.
Flexible applications for the Acquaspar UF filter:
- Installed at the cold water inlet
- In hot water systems – e.g. after the boiler
- Directly at the point of use (shower, sink, bathtub)
