Peak Series Activated Carbon+Ion Exchange Filter Attachment improves taste and filters heavy metals

What Our Gearhead® Experts Are Saying:

"I always pack the Peak Series Carbon Filter when I’m using my LifeStraw squeeze bottle—it noticeably improves taste and takes out stuff like chlorine and metals. It’s lightweight, lasts a while, and makes backcountry water more palatable."

We count on the LifeStraw Peak Series Activated Carbon+Ion Filter Attachment to make backcountry hydration cleaner and better tasting. Whether we're pulling water from alpine streams or refilling on the trail, this filter add-on takes the edge off harsh-tasting water and gives us added peace of mind by reducing heavy metals and chlorine.

Designed to integrate seamlessly with the LifeStraw Peak Series systems, it connects to squeeze bottles, gravity filters, and solo filters with ease. Activated carbon paired with ion exchange filtration improves flavor and removes contaminants like lead, cadmium, and mercury—making each sip safer and smoother. It’s compact, reliable, and a must-have upgrade for any outdoor water setup.

Bought for Emergency Kits

We purchased the LifeStraws for our Grandchildren for their emergency kits. We just had two added for a total of 7. They each have a LifeStraw. We believe in being ready in case of a grid failure or disaster. Thank you for providing drinkable water to those who need it worldwide 🌷
