PAUL removes bacteria, viruses and other pathogens almost up to 100% (avg., up to 99.99999%) from contaminated water without needing chemicals or electrical energy.

PAUL can be operated even by illiterates in emergencies and already 4,500+ PAUL units exist in 91 countries worldwide.

PAUL has a 10+ year lifetime, so it can also be used to build a PAUL STATION for a permanent water supply. Such a PAUL STATION offers communities, schools, hospitals and the local population the opportunity to reduce their water costs and additionally earn their own money. So far, 500+ PAUL STATION arrangements have been installed worlwide.
