- Does it filter viruses?
- No. The hollow-fiber filter catches bacteria, parasites and microplastics but not viruses. In areas with viral risk, use it with purification tablets or boil the water.
- How often does the filter need replacing?
- LifeStraw rates the filter for hundreds of liters of use. Replace it when flow stays slow after backflushing or when the rated volume is reached.
- Can I use it with tap water at home?
- Yes. It works on tap water as well as stream and lake water, which makes it useful for travel and everyday refills.
- Can I put juice or soda in it?
- No. Use plain water only. Sugary drinks clog the filter and are hard to flush out.
- Can I freeze the bottle?
- No. Freezing can crack the filter and the bottle. Keep it from freezing and store the filter wet between trips.
- Is it better than a pump filter?
- It is simpler and lighter because you drink through the filter. A pump or gravity system suits groups and large volumes better.
- Where is the Lifestraw Go Series Water Filter Bottle cheapest?
- At Backcountry, for $44.95, as of our latest check.
