The technology behind LifeStraw filters

Depending on where your water comes from, contaminants unique to that area can make it unsafe to drink.

Bacteria and parasites are the most common pathogens in rivers, streams and rural areas. Tap water, too, can contain chemicals and harmful levels of heavy metals like lead.

WHAT ABOUT CHEMICALS?

Some LifeStraw products use a two-stage filtration process. In addition to the hollow fiber membrane, a carbon capsule absorbs chemicals like chlorine and pesticides.

More advanced carbon filters like the LifeStraw Flex also reduce heavy metals like lead.

DIFFERENT LIFESTRAW PRODUCTS DO DIFFERENT THINGS

Bacteria and parasites are bigger than the pores in the filter. Water is able to pass through, but contaminants larger than 0.2 microns remain trapped.
