Pros & Cons Side by Side

LifeStraw Peak Series Squeeze Filter

0.1 micron hollow fibre removes bacteria, parasites and microplastics — WHO-compliant purification
1,000-litre filter lifespan covers years of weekend hiking and extended expeditions
80g is ultralight — costs nothing to carry 'just in case' on every hike
Squeeze mechanism works without pumping — gravity or squeeze fills bottles from any source
LifeStraw donates a school year of safe water to a child for each filter purchased — ethical dimension

Doesn't remove viruses — Sawyer Squeeze and Katadyn add chemical treatment for viral risk areas
Squeeze mechanism requires practice to use efficiently
Not suitable for murky glacial or silt-heavy water without pre-filtering
