For LifeStraw Flex and Play with Lead Reduction 

LifeStraw Activated Carbon + Ion Exchange Filters reduce heavy metals, like lead, and improve water taste by removing chemicals such as chlorine, odors.  The activated carbon has been treated with specific processes to open millions of tiny pores between carbon atoms. LifeStraw uses an advanced, special formulation that is made from fibers, instead of traditional granulated carbon, which improves longevity and performance.  The filtration process works via adsorption - contaminants become trapped inside the pore structure of the carbon and bind to the surfaces. The ion exchange contains a resin with cations that are bound to fibers and non-harmful.  When liquid containing other dissolved ions passes through the fibers, the dissolved ions in the water (like lead and other heavy metals) are exchanged for the non-harmful ions currently bound to the fibers. As a result, the harmful elements are trapped and the non-harmful ions are released, making the water safer to drink.

LifeStraw Activated Carbon + Ion Exchange filters reduce lead and other heavy metals and chemicals like PFAS, glyphosate and chlorine while improving water taste. The activated carbon has been treated with specific processes to open millions of tiny pores between carbon atoms. LifeStraw uses an advanced, special formulation that is made from fibers, instead of traditional granulated carbon, which improves longevity and performance. This process works via adsorption - contaminants become trapped inside the pore structure of the carbon and bind to the surfaces. The ion exchange contains a resin with cations that are bound to fibers and non-harmful.  When liquid containing other dissolved ions (such as heavy metals like lead) passes through the resin, the dissolved ions in the water are exchanged for the ions (non-harmful) currently bound to the fibers.  As a result, the harmful elements are trapped and the non-harmful ions are released, making the water safer to drink.  

These activated carbon and ion exchange formulations are carefully designed for removal of specific chemicals and heavy metals that are harmful to human health while allowing other healthy nutrients (such as sodium, calcium and magnesium) to pass through.  The LifeStraw Home Activated Carbon + Ion Exchange filter also has a special formulation that maximizes contact surface with the ion exchange and carbon fibers which allows for highly advanced performance in the removal of chemicals and heavy metals as shown by testing results for efficacy against over 30 contaminants.
