- Does it filter viruses?
- No. It is a hollow-fiber filter that removes bacteria and protozoa, not viruses. For virus-risk water, use a purifier with chemical or UV treatment.
- How long does the filter last?
- LifeStraw rates the cartridge for about 2,000 liters of water, depending on turbidity. Replace it when flow becomes hard to maintain.
- Can I use it with tap water?
- Yes. Fill it from any tap and squeeze through the filter. It is also fine for lake, river and stream water.
- Is it freezer or dishwasher safe?
- No. Freezing can damage the hollow fibers, and the filter should not go in a dishwasher. Hand-wash the bottle and backflush the filter.
- How does it compare with a hard filter bottle?
- It packs smaller and lighter but needs squeezing and has no rigid body. Hard bottles stand up and flow faster but take up pack space.
- What is in the box?
- The collapsible 1L bottle with the filter cap. Check the listing for whether a backflush syringe or carry loop is included.
