Bottle makes dirty water drinkable

The way fresh water is supplied to disaster-hit regions could be revolutionised after an Ipswich-based businessman invented a £190 bottle that makes foul-smelling water drinkable in seconds.
Conventional filters can cut out bacteria measuring more than 200 nanometres but not viruses, which typically are 25 nanometres long.

Mr Pritchard's bottle can clean up any water - including faecal matter - using a filter that cuts out anything longer than 15 nanometres, which means that viruses can be filtered out without the use of chemicals.

They have them. They are called membranes and require skilled machinists to produce. One of my cousins developed them. The primary use is in desalinization. Sounds like someone has scaled this to a small application.
