Clean Water, simple and scalable

PAUL is a reliable portable water filtration system for remote communities, humanitarian aid, disaster relief and many more applications.

Meet PAUL!

PAUL, the “WaterBackpack”, was designed to be used when available water is contaminated and resources are limited.

removes bacteria, viruses and other pathogens almost up to 100% (on average, up to 99.99999%)
gravity-driven membrane filtration
no chemicals necessary
no electrical energy necessary
very simple to use and maintain
extremely durable and long-lived
small and portable (23 kg, equipped with backpack straps)
can be implemented as a permanent filtering installation

How it works

Using PAUL is very simple. It just requires 4 steps to get clean water:

Collect Water

First, water needs to be collected from a nearby source using a bucket or similar. Potential water sources can be e.g., rivers, wells, rain water tanks, reservoirs etc.

Pour water into PAUL

PAUL needs to be filled with water so that gravity can push the water through the filter.

Draw clean water from PAUL

By opening the hose valve at the front of PAUL, the filtration process begins and filtered water can start to be collected immediately.

Drink

Filtered water can be used for drinking, food preparation etc. Cheers!

Distribution

In total, over 5000 units PAUL units have been deployed in 95 countries across the world.
