LifeStraw filters (LifeStraw, LifeStraw Go) and purifiers (LifeStraw Family and LifeStraw Mission) do not remove contaminants that are dissolved in water including chemicals (like arsenic), brackish water or salt from salt water. 

They should not be used in areas where there is known chemical contamination and should not be used to consume pool water or urine. 

Our products also do not remove fluoride.
