【Exclusive Threaded Design】This coupling uses a unique dual-thread structure compatible with LifeStraw personal water filters on one end and 28mm standard-thread bottles or water bags on the other. It gives your water filter a better way to operate, enabling efficient filtration. (Note: Only compatible with the LifeStraw personal water filter, not suitable for other series.)
【Safe & Easy Drinking】With this coupler, you can drink comfortably without crouching down, struggling to sip, or risking slips near water sources. It also allows you to set up a simple gravity water-filtration setup, freeing your hands and making outdoor hydration much easier.
【Personal to Shareable】Just connect your filter and flip the bottle—within about 30 seconds you can fill a bottle with clean water to share with your hiking partners or pets. This allows your personal filter to serve multiple people—perfect for reducing pack weight during group adventures.
【Easy to Use】The water filter coupling kit includes clear flow-direction arrows, helping you connect your water filter and bottle or hydration bag quickly. Removing the adapter requires a firm pull from both sides, so we recommend leaving it attached for quicker setup next time.
【Lightweight & Portable】This adapter is ultra-compact and takes up almost no space in your backpack. It can stay attached to your water filter without adding bulk, and each set includes two adapter couplers for easy replacement, making it an essential tool for outdoor adventures.
