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).
Conclusions
So what did I learn?
- The Sawyer Squeeze maintained a good flow rate after 17 days of constant use (1.45 liters per minute).
- The Sawyer Squeeze flow rate decreased about 0.6% per day over the 17 days of use.
- Backwashing the Sawyer Squeeze restored the flow rate to 99.4% (1.59 liters per minute) of the original flow.

MEDIA MENTIONS
Of all the creepy crawlers, ticks keep me on high alert. They can be very tiny in the nymph stage and difficult to see. They love to hang out in tall grasses along the trail and hitch a ride on hikers passing by. I plan on treating most of my clothes and gear with Sawyer Permethrin.
MEDIA MENTIONS
Ultra-compact and lightweight
MEDIA MENTIONS
I would often just drink directly from the sawyer squeeze if I was feeling lazy- which by the way works wonderfully.
