PureStream Survival Water Filter Straw

Dip. Sip. Survive. Turn a stream, a lake or a puddle into drinkable water in seconds.

You Can Last 3 Weeks Without Food. Only 3 Days Without Water.

A broken water main. A boil-water notice. A hike that takes longer than planned. A flood, a hurricane, a car stuck far from the nearest store. When clean water disappears, it disappears fast, and the shelves empty first.

Bottled water is heavy. Purification tablets taste awful and take time. Unfiltered water can carry bacteria and parasites you can't see.

Meet PureStream

• ✦ Filters up to 4,000 L (1,056 gal). That's about 8,000 bottles of water from one tiny filter.
• ✦ Instant. Clean water the moment you sip. No waiting, no aftertaste.

Ask Yourself One Question

If the tap stopped working tomorrow,

where would your family's next glass of water come from?

How to Use

1. Remove the caps from both ends.
2. Place the inlet end in the water source, or attach it to a bottle or hydration bag. Follow the arrow on the filter for the flow direction.
3. Sip through the outlet. The first few sips prime the membrane.
4. After use, blow air back through the filter to clear it, then cap both ends and let it dry.

Tip: one for the car, one for the emergency kit, one for every backpack. That's what the 3-Pack is for.
