A prototype water filter from Seldon Laboratories eliminates the biological nasties found in untreated water. Drinkable water is delivered just by sucking water through the tube. No chemicals and no electricity are needed.

The clever bit is the use of carbon nanotubes which are bound together to form a very effective filter.
