663 million people rely on unimproved sources, including 159 million dependent on surface water.
Contaminated drinking-water is estimated to cause 502 000 diarrhea deaths each year.

A 30cm x 40 cm Swoxid panel can supply 0.5-1 liters of sterilized water per hour.

The operation of Swoxid panel does not require much expertise. It is gravity-powered. One should only pour the contaminated water into the inlet and collect the treated water at the bottom of the panel.
The Swoxid panel does not require consumables that are difficult or too expensive to obtain.
The panel should be back-washed periodically with acidic liquids, but relatively easily accessible acidic fruit juices (ex. lemon juice), vinegar or fizzy drinks can be applied for this purpose.
