If you're going to carry one survival tool with you, traveling, evacuating, or just to have in the house, this magical item will turn dirty water into clean water. It is highly transportable and next to weightless. This filter even takes out some heavy minerals. Works as a straw, in a water bottle, or even a hydration pack.
LifeStraw Flex Multi-Function Water Filter System
Bottom line: So small that it fits anywhere, so you have access to clean water anywhere. Not as ideal for longterm use.
Recommended for: Home, go bag, vehicles, away shelter.
No. of units recommended: 1 for each member of your family; ideally in each shelter and go-bag.
This is dead easy to use. Stick it into a water source and drink. However, it's not as ideal for creating large quantities of water. For that, turn to the Family or Mission size filters.
