Straight from the source.
You always felt like your filter was just a middle man between your water bottle and the river, so cut out the middle man and use the LifeStraw Go 2-Stage Filtration Water Purification System. This water bottle features a built-in filtration system that filters water as it flows through the straw when you're drinking.
