LifeStraw Peak Series Squeeze.
LifeStraw's backcountry squeeze filter with a microbiological purifier cartridge. The budget-friendly squeeze option from the brand that popularized portable filtration.

The Verdict.

“The budget squeeze filter with an optional virus-removal upgrade. $35 buys Sawyer-comparable filtration with the ability to add purification for $15 more. Newer to market but backed by LifeStraw's water-treatment expertise.”
