Guthooks Guides: How My Sawyer Squeeze Filter Performed on My JMT Thru-Hike
How My Sawyer Squeeze Filter Performed on My JMT Thru-Hike
I tested a brand new Sawyer Squeeze on my 17 day thru-hike of the 211 mile John Muir Trail (250 actual miles). The filter was not backwashed during the entire trip.
Filtration Flow Rate
After 17 days of use without backwashing the Sawyer Squeeze, the flow rate dropped from 1.60 liters per minute to 1.45 liters per minute. After backwashing with just 2 liters of clean water using the Sawyer backwashing coupler, the Sawyer Squeeze flow rate was almost completely restored to its new condition (1.59 liters per minute).
