## Description

What is the Survival Water Filter?The Survival Water Filter is a16.5x3cm portable water filter straw which is designed to convert dirty or contaminated water into clean drinkable water. Water will travel through the bottom of the filter and into the hollow fibre membranes. From there it flows through the coconut activated carbon and through to the mouthpiece - leaving you with BPA Free, chemical free, bacteria free, particle free, delicious tasting water.How It Works: Step 1: Remove caps. The mouth cap also doubles as a whistle. Step 2. Put the straw directly into your fresh water source or screw it to any standard plastic bottle (28 mm). Step 3. Wait 15 seconds and then begin sucking water from the mouthpiece. If you've attached a bottle, turn it upside down and squeeze the water out.Reusable: When you're done with your straw, blow the excess water out and leave the caps open until it has dried. Our well thought through design allows you to use the bottle to squeeze water through the filter, rather than having to suck it from an open water source. We've also made it smaller, lighter, more durable, and gave it the versatility of a survival kit. We've also added an extension tube that allows you to drink comfortably if you don't want to put your face so close to the water.What is the shelf life of the Survival Water Filter? Your straw's expiration date does not start until you open and use it. Once used, the straw should be replaced after 5 years or about 400 gallons of water have passed through it.Package includes: Signalling Mirror: A mirror can be found inside the top which can be used for signalling. Tourniquet: Added rubber tubing which can be used as an extension or first aid tourniquet. Bear Whistle: Added a removable whistle to the cap for emergencies. Compass: Added emergency navigation for hikers and backpackers.
