What’s the difference between the original LifeStraw personal water filter straw and the LifeStraw Peak Series Water Filter Straw?

Great question, we're glad you asked!

We took our original LifeStraw— the most popular outdoor water filtration device!—and reimagined it. While both straw filters use membrane microfiltration technology to filter bacteria, parasites, microplastics, sand and silt from dirty water, the Peak Series Personal Water Filter Straw is designed for improved backcountry use. What does this mean?  

This means it boasts an enhanced flow rate for easy sipping and an easy-grip design.  
It also means a re-engineered filter with enhanced microfilter performance to reduce clogging from sand and silt.  
It means extreme durability with premium materials to make it tougher and ultra leak-proof.  
It also means more versatility and compatibility with other products! The Peak Series Personal Water Filter Straw features a built-in gravity hose attachment and a removable bottom cap which reveals threading compatible with countless systems including squeeze bottles and most single-use bottles.
