Portable Water Straw----A good choice for outdoor survival activity! The Survival Water Filter is a 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, and 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 bottled, turn it upside down and squeeze the water out. Warm Tips : 1.For the first time using, the filter cartridge is dry, you need to try 5-8 seconds to suck the water out. 2.It is normal to smell a plastic taste when you absorb the water with the straw at first time. 3.Do not absorb too muddy water with the straw, otherwise may block it. 4.Absorbing the water with your mouth until the straw was full of water, then squirt the water out. (Repeating the step for 5-6 times can help to clean the straw.) 100% Satisfaction Guarantee: If you have any problem or suggestion, please feel free contact us, your any opinion is important and a great encouragement to us!
