Filtering Bottles

What is a water filter bottle for?

A water filter bottle has a filter built into its body or drinking spout. Fill it with water from a river, lake or other natural source and drink directly, without boiling the water or using separate purification tablets. It’s a practical option for trekking, survival situations or self-supported expeditions where access to drinking water is not guaranteed.

Which water filter bottle should you choose?

This category includes bottles from leading brands such as Katadyn, LifeStraw and Hydrapak in a range of capacities. Options include the lightweight, compact 0.5 L Hydrapak Ultraflask+, the Katadyn BeFree AC in 0.7 L and 0.9 L sizes, and the LifeStraw Go in 0.53 L stainless steel or 1 L for those who want to carry more water. Your choice mainly depends on how long you’ll be out and how much water you want to filter before refilling.
