- What does the LifeStraw SIP filter out?
- Its hollow-fiber membrane traps bacteria and parasites such as E. coli, Giardia and Cryptosporidium. It does not remove viruses, heavy metals or dissolved chemicals.
- Is it a replacement for a full water purifier?
- No. It filters only the water you sip through it, so it suits personal drinking on the go. For treating a whole bottle or virus-risk water, use a purifier or filter system.
- How do I keep it flowing well?
- Backflush it regularly by blowing or pushing clean water back through the filter, and let it dry with the cap off. A clogged filter is the usual cause of slow flow.
- Can I use it on any water source?
- It works on tap water, bottled water and clear surface water. Avoid very muddy or cloudy water, which clogs the filter faster.
- What comes in the box?
- The stainless steel SIP straw and a protective carry case.
