Pros and cons of the LifeStraw Peak Series Collapsible Squeeze 1L
Pros
- Works as a bottle or a squeeze filter and also as a straw or inline.
- Rated for 500 gallons before the flow stops on its own.
- At 3.2 oz it adds little to a go bag.
Cons
- Heavy metals and viruses are outside what the maker says it removes.
- Only one liter at a time so a household needs more than one or a gravity setup.
