Turn natural freshwater into clean drinking water instantly. FiltSipy uses ultrafiltration technology to filter out sediment, heavy metals, and micro-particles on any outdoor adventure or emergency.










Advanced hollow fiber membranes eliminate fine impurities, sediment, chlorine, and unwanted particles from streams, lakes, and natural sources for immediate, clean hydration.
Built for long expeditions and emergencies, a single FiltSipy straw reliably purifies up to 5,000 litres of water, replacing thousands of single-use plastic bottles on your journeys.


Screws directly onto standard water bottles or hydration squeeze bags on both ends, allowing rapid gravity filtration, direct sipping, or clean water transfer with ease.



"For remote backcountry expeditions, reliable water purification is non-negotiable. FiltSipy's 0.01μm hollow fiber membrane delivers outstanding filtration efficiency in an ultra-portable form factor."
