Key features & specs

How it compares

When compared to traditional pump filters or gravity bags, this LifeStraw model is significantly faster and more versatile due to its universal threading. It offers a more sustainable alternative to chemical purification tablets and avoids the bulky plastic waste associated with single-use bottled water.

How to use it

1. Remove the top and bottom leak-proof caps from the device.
2. Screw the filter onto any standard 28mm plastic water bottle or hydration reservoir.
3. Squeeze the bottle to push water through the filter into a clean container or drink directly from the mouthpiece.
4. After use, blow air through the mouthpiece to clear out excess water and debris.
5. Recap the device to prevent cross-contamination during transport.

The flow rate is incredible for such a small device, and I love that the brand gives back to communities in need.
