Important information from LifeStraw: Some packaging for these bottles may have outdated filtration information. Regardless of what is printed on the package of the bottle you receive, LifeStraw performed extensive testing and found the filters have a 4,000L (or 1,000 gal.) lifespan. If you receive a bottle with the older packaging that displays a shorter lifespan, LifeStraw wants to assure you the filter can be used for up to 4,000L before it must be replaced.
