Sawyer Water Filter Field Test

This filter was tested at 9600 feet in the Sierra Nevada Mountains in September 2018. The system I put together worked great. The Sea to Summit 10 liter collapsible bucket made it it easy to get water from a lake or stream. Have a cap over the clean water side of the filter prevented dirty water getting there while the filter was stored in my pack.
