Point-of-use filters can be used as a temporary measure in cases of microbial contamination of the potable water installation before and during the reconstruction, measures to restore and maintain drinking water quality in the short term (see DVGW-Standard W 551-2). They serve to protect the consumer. “Point-of-use” means that there are no further technical components between the filter and the use of drinking water from an outlet. 

This brochure gives advice for the selection, installation and application of point-of-use filters.
