Featuring an integrated whistle, compass, signaling mirror, and extension tube, it connects easily to any standard plastic bottle or water bag. Designed for outdoor enthusiasts and emergency preparedness, it delivers up to 1500 liters of clean, chemical-free water in a lightweight, durable form factor. ## 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. Review: Great product - I bought this and a foldable bottle for a couple of pounds with a standard size thread hoping the thread would fit. Can confirm it does so can be attached to a foldable bottle and squeezed out into a cup , pan or other bottle like a sawyer filter, but with a carbon filter which the sawyer filter doesn't have. Seems well made and of good quality. Review: Keep the packet it comes in. - Bought for my son (13yrs) he loved it although the instructions say it comes with a bag but it’s not very clear if it means the packet it comes in or if there should be a separate bag that comes with in. If it should be the former then it would be helpful if that’s made clear on the packaging (my son is like a rabid dog with it comes to opening things) ## Features - 4 in 1 - WHISTLE, MIRROR, COMPASS, and Extension TUBING - Be prepared for any survival situation. - PORTABLE WATER FILTER - Eliminates bacteria at .01 Microns. - ADVANCED PURIFIER - removes 99.9% waterborne protozoan parasites. - BOTTLE ATTACHMENT - Connect your filter straw directly to any standard plastic bottle or water bag - SUPER SMALL- Only 16.5x3cm for lightweight hiking, backpacking, camping, and hunting. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01LYJCWQX | | Batteries included? | No | | Brand | Revive H2O | | Customer Reviews | 4.2 4.2 out of 5 stars (21) | | Date First Available | 18 Sept. 2016 | | Is discontinued by manufacturer | No | | Manufacturer | Purposefull Products | | Material type | Plastic | | Package Dimensions | 28 x 11 x 2.6 cm; 81.65 g | ## Product Details - **Brand:** Revive H2O - **Capacity:** 1500 litres - **Item weight:** 82 g - **Manufacturer:** Purposefull Products - **Material:** Plastic - **Package information:** Bag,Bottle - **Purification method:** Hollow Fibre Membrane ## Images ![4 in 1 Survival Water Filter Straw + Whistle + Compass + Mirror - Can Connect To A Bottle or Bag.
