==Technical specification== ====Operation==Construction, operations and maintenance==
Place LifeStraw® in water and sip through the mouthpiece. Regularly blow through the LifeStraw® after drinking to keep the filters clean and to prevent them from clogging. To clean, wipe your LifeStraw® with a soft cloth
====Treatment Efficiency====
The University of North Carolina evaluated the performance of LifeStraw® personal water filter with regard to reduction of bacteria and viruses, level of iodine release and silver concentration in the filtered water. LifeStraw®:
* removes particles down to 15 microns <br>
====Maintenance====
The filterpen is quite sensitive to shocks, so avoid dropping or collisions. However, as far as proper maintenance is conducted, no real damage should occur.
====Manufacturing====
Vestergaard SA Tested by the University of North Carolina. LifeStraw® can be donated through various non profit organisations.
====Estimated Lifespan====
Shelf-life is 2 years at 25°C or 1 year at 30°C.
