Mercy Relief in Singapore and AGplus Technologies have found new ways to bring clean water to those in poverty-stricken areas or in crisis zones.

They have come up with three new creations - a water container, a water bottle and a straw - that use nanosilver embedded in ceramic filters. This will allow people can turn water from rivers and ponds almost instantly into clean, safe water for drinking.

The idea of a nanosilver ceramic filter in straws and bottles is the first in the world, and was created by Dr Liu Hongjun from AGPlus Technologies during the 2008 Sichuan earthquake.

According to the World Health Organisation, around 1.1 billion people still do not have access to clean drinking water.
