Why We Like It

This is the perfect companion for backcountry excursions. Even if you think you're porting enough water, as light, compact and effective as this filter is, there's just no excuse to leave it behind. Better safe than thirsty! The filter very effectively does what it's supposed to do - it's certified to remove bacteria, cryptosporidium, and giardia to EPA standards. And the Frontier Pro goes above and beyond by reducing chemicals, chlorine, bad taste and odors and is certified lead free to NSF/ANSI-372 . 


Minimal weight, quality design and the ability to connect to water bottles, bladders and gravity flow systems, or even drink right from a straw, make this filter incredibly versatile. It filters out 99.9% of bacteria and cysts to ensure your backcountry water is safe.
