The rapid and easy installation process means that these sterilization filters can be used flexibly and can thus reduce the infection risk for patients and medical staff. When pathogens have been found in the water, sterile water filters are installed, for example on the tap or shower, and ensure that pathogens are reliably held back throughout the defined service life. 

The sterilization filters are exchanged regularly: attention should be paid to the service life given by the manufacturer for each sterilization filter. Single-use and reusable systems are available depending on the manufacturer. Some of the available sterilization filters include a silver- or copper-coated sterilization filter outflow for additional microbiological protection against colonisation by pathogens.

In the non-medical domain, water sterilization filters are normally used when Legionella bacteria have been found. In this way it is possible to avoid banning shower use in residential complexes or closing sports halls and indoor swimming pools; point-of-use sterilization filters can also be used to protect guests at seasonally-operated hotels and holiday centres.
