High-Volume Hollow-Fiber Filtration for Efficient Group Hydration

The Platypus GravityWorks Filter Cartridge is the critical engine behind one of the most trusted water treatment systems for backcountry groups and expedition teams. Utilizing advanced 0.2-micron hollow-fiber technology, this cartridge provides a robust defense against 99.9999% of bacteria and 99.9% of protozoa, including Giardia and Cryptosporidium. Designed for high-volume performance, it filters water at an impressive rate of up to 1.75 liters per minute, allowing you to process large quantities of safe drinking water without the tedious, repetitive pumping required by traditional portable filter systems.

Reliability in the field is paramount, which is why the GravityWorks cartridge is engineered for simple field-maintainable backflushing, allowing you to restore flow rates instantly if the filter becomes clogged with sediment or glacial silt. It is a lightweight, compact solution that integrates seamlessly into your existing GravityWorks reservoir setup, ensuring you remain hydrated without the weight of bulky, chemical-dependent treatment kits. Whether you are leading a scout troop, organizing a group backpacking trip, or managing basecamp water for a climbing crew, this replacement cartridge ensures your team stays fueled and healthy throughout the duration of your trip.
