The filter threads instantly onto mushy flasks and disposable water bottles with a 28mm opening, together with Smartwater bottles and the CNOC Vesica mushy bottle, which is now bundled with the Sawyer Squeeze. You may sip straight via the highest valve or squeeze a bottle or mushy flask to push clear water right into a cook dinner pot, reservoir, or one other bottle. There’s a easy twist-to-open cap on the “soiled finish” and a detachable cowl on the clear finish to guard the mouthpiece from filth and unintended cross-contamination.
The Solo’s standout characteristic is its dimension and weight. It’s concerning the dimension of a Nuun Electrolyte Sleeve, and weighs 1.7 ounces dry, disappearing right into a operating vest or a hip belt pocket. Each the highest and backside caps seal properly after use and don’t leak, which is a must have that even the Sawyer Squeeze water filter (when bought individually) can’t declare.

Pre-filtering your water with a clear bandana or espresso filter can even prolong the efficiency of your water filter.

It’s constructed utilizing the identical expertise as different water filters designed for backcountry use in North America, the place viruses are uncommon. In areas with potential viral contamination (crowded camps, catastrophe zones, or some worldwide journey), pair it with Aquamira chlorine dioxide drops or chlorine dioxide tablets after filtering. If chemical contamination is a priority, you’ll want a unique filter with activated carbon or a air purifier that handles heavy metals. Or you may simply purchase bottled water in case you’re close to civilization.
Lifespan
LifeStraw charges the membrane for as much as 2,000 liters beneath preferrred situations. Actual-world lifespan relies on sediment load and upkeep, so common backflushing is crucial. Chilly-weather warning: If the filter freezes after it’s been moist, inside fibers can crack and compromise security. Preserve it in an internal pocket close to your physique in freezing temps and exchange it in case you suspect a freeze occasion.
