What's in the box: one Gravity purifier with virus removal plus four of our lightest filter straws. Built for the person keeping a family or a friend group supplied when the water gets weird. Full-coverage protection, no extra weight to carry.
The Sip straws take out bacteria and parasites. The Peak Purifier goes further and removes viruses too, along with bacteria and parasites.
Gravity does the work at a high flow rate of 30L/hr, so there's no pumping and no external energy source needed.
LONG LASTING: the ultrafilter membrane is rated for a lifetime capacity of 18,000 liters, which works out to about five years of safe drinking water for a family of five. Each individual Sip straw is rated for 2,000 liters.
