I would recommend something like the Sawyer Squeeze (not the Sawyer mini) over the life straw. First of all, the normal life straw needs suction to push water through the filter, while with the Sawyer Squeeze you fill a water container or standard water bottle with dirty water and push it into a container. Also it has a higher flow rate of almost 0.5 gallon per minute and will filter up to 100′000 gallons of water with proper backflushing (vs. 1′000 gallons with the life straw). It costs around $35 (vs $13) but you can hydrate your whole neighbourhood with enough non-drinkable water available.
