How to Use

1. Take the cap off the LifeStraw.
2. Hold the Lifestrpaw vertically in the water for about 30 seconds, to allow the water to rise up about halfway through the filter.
3. Do five quick sucks and the water will start to flow.

When the Lifestraw reaches the end of its life, it will stop delivering water, so you will never drink contaminated water.

Overall Value

The Lifestraw can filter up to 1000 litres of water, which makes it pretty economical. It can filter down to 0.2 microns, which means it will remove 99% of waterborne bacteria and protozoa. Since it is very affordable, it's a great value for a disposable water filter.

Lifestraw Personal Water Filter is very reasonably priced at Amazon.
