Detachable Design
Our WS02 water filter straw is the only detachable straw on the market. Both ends can be disassembled, making it easy to replace the filter element anytime and anywhere. This extends the lifespan of the straw and saves you money. Plus, it’s truly reusable and more environmentally friendly.
Superior Backwash Solution
Cleaning is a breeze with our water filter straw. The detachable mouthpiece connects with a common bottle for backwashing, eliminating the need for an extra syringe. No more complicated cleaning processes. And unlike water purification tablets or syringe-based filters, it never expires and doesn’t require batteries.
4-Stage Filtration
Our backpacking water filter uses a 4-stage filtration system. This includes a 0.1-micron hollow fiber ultrafiltration membrane, a coconut shell GAC filter, and two double PP fiber filters. This ensures it removes 99.99999% of E. coli, odor, iodine, chlorine, and heavy metals, making the water taste better. Moreover, it maintains an optimal flow rate of 500ml/min, even with the smallest filter pore size. With a long lifespan, it can provide at least 20,000 liters of clean water.
Versatile Filtering Modes
Use our filter straw directly as a personal water filter. It’s also perfect for connecting with soft water pouches or standard disposable water bottles to get pure water. In emergencies, you can even add an extension silicone pipe (not included) for drinking over a longer distance. Plus, it works well as a replacement gravity filter, providing enough fresh water for your whole family or group.
Safier Survival Tool
Our water filter meets EPA filter standards and is made from food-grade, BPA-free materials. It’s ideal for backpacking, hiking, travel, camping, and emergency preparedness. Even better, it’s a safe and practical gift for hikers or anyone needing reliable water purification.
