The LifeStraw makes dirty water clean

Q12. How can LifeStraw be effectively utilised? At regular intervals, it is recommended to blow out the last mouthful of water as well as some air through the LifeStraw. This will clean the pre-filters of whatever sand, silt and debris that might have got stuck in the textile filters.

Q13. Does LifeStraw filter arsenic, iron, fluoride and other heavy metals? No. Q14. What is the impact of saline water on the lifetime of LifeStraw? It is expected that continuously drinking saline water through the LifeStraw would reduce effective life to 350 litres.

Q15. Can I share my LifeStraw with other people? It is not recommended that you share your LifeStraw with others. Any outside contamination of the LifeStraw will not be compensated by inside purification.
