What to Compare Before Buying
- Filter rating: This model uses a 0.01 μm ultrafiltration membrane. Compare the filtration level with the level you want from a personal water filter.
- Capacity: The stated capacity is 1000 L. Check whether that is enough for your expected use.
- Size and weight: At 30 g and 2 cm by 15 cm, it is aimed at compact carry. Compare that with the space in your pack or kit.
- Format: This is a direct-drinking straw rather than a bottle or pump system. Make sure that suits how you plan to take water.
Before You Decide
Confirm that you want a straw-style personal water filter rather than a bottle, pump or larger purifier. Check the 0.01 μm filter rating, 1000 L capacity and 30 g weight against the way you plan to carry and use it. The 2 cm by 15 cm size is also worth checking if space in your kit is limited.
