The majority of LifeStraw products for individual use are microfilters with an absolute pore size of 0.2 microns which remove bacteria, parasites, microplastics, and dirt/silt.
LifeStraw also manufactures ultrafilters/purifiers that, in addition to the above contaminants, also remove viruses. The absolute pore size on these purifiers is 0.02 micron.
