What is the lifespan of the LifeStraw Sip?

1,000 liters or 264gallons.  If you take an assumption of someone drinking a bottle of water a day with the straw (0.5 liters), this in principle means the product can last over five years with everyday use.  We expect most people will not end up using the product daily, so the lifespan should be even greater than five years.
