How does the LifeStraw activated carbon + ion exchange filter work?

LifeStraw activated carbon + ion exchange filters reduce lead and other heavy metals and chemicals such as PFAS, glyphosate, and chlorine while enhancing water taste. The activated carbon has been treated with specific processes to open millions of tiny pores between carbon atoms. LifeStraw uses a unique advanced formulation made of fiber instead of granulated carbon, which improves longevity and performance. The filtration process works via absorption - contaminants get trapped within the pore structure of carbon and adhere to surfaces.

The ion exchange component contains a resin with cations that are bound to the fibers and are not harmful. When liquids containing other solvent ions pass through the fibers, the dissolved ions in the water (such as lead and other heavy metals) are exchanged for the non-harmful ions in the fibers. As a result, harmful elements are trapped, and non-harmful ions are released, making the water safer to drink.

These activated carbon and ion exchange formulations are carefully designed to remove specific chemicals and heavy metals that are dangerous to human health while allowing other healthy nutrients (such as sodium, calcium, and magnesium) to pass through. The LifeStraw Ion Exchange + Activated Carbon Filter also has a unique formulation that maximizes the contact surface with the ion exchange and carbon fibers, thus enabling highly advanced performance in removing chemicals and heavy metals, as shown in the results efficacy tests against more than 30 contaminants.
