  • Safe water hygiene 
  • Operating time up to 2 months
  • CE-marked medical device 
  • Environmentally friendly and efficient reusable product

Germlyser® D

The Germlyser® D is a CE-marked medical device. This reusable water filter is a terminal sterile filter with a 0.2 µm hollow fibre membrane which displays retention of at least 7 log units1. Thereby offering reliable protection of patients against infections caused by all critical waterborne germs such as legionella, pseudomonads, staphylococci or stenotrophomonas over a service life of up to 2 months, depending on the water quality.

The chemical composition of the water is not altered. The hygienic design and the use of bacteriostatic material in the housing and bactericidal material at the filter outlet prevent retrograde contamination incurred by splash water or physical contact.

On expiry of the service life, the respective filter must be changed and returned for reprocessing. This filter change is easy to complete thanks to installation of the appropriate quick-release couplings.

An individual product marking on each filter guarantees traceability and facilitates the documentation process within the framework of hospital hygiene procedures.

Reprocessing and delivery service

The Aqua free Germlyser® reusable filter system offers customers a safe, environmentally friendly and efficient alternative to single-use filters. Aqua free manage the logistics of delivery and return of filters – which is included in the rental rate of the filters – reducing inventory costs and administration.

All filters are reprocessed by Aqua free using a validated process and following strict quality standards. Quick-release couplings allow filters to be safely changed in seconds and barcodes, identifying filter and location, ensure simple logging and documentation of the whole change process.

Aqua free reusable filters deliver a significant reduction in waste and carbon footprint compared to single-use filters.
