The LifeStraw Sip is a slim straw-style personal water filter with a stainless steel casing and a 0.2 micron membrane. It filters up to about 1,000 liters depending on how clean the source water is, and it comes with a carry case for a backpack or bag. It suits hikers, travelers and commuters who want a light backup filter for tap or treated water. Against pump filters and gravity systems it is simpler and lighter, but it has no bottle, no pump and no virus protection, so it is a personal sipping filter rather than a group purifier.

Owners treat the Sip as a compact, sturdy backup filter for travel and day hikes. They like the steel body and the case, and note that it is slower to drink from than a bottle filter and clogs on dirty water.
The LifeStraw Sip is a reusable, straw-style personal water filter with a slim, compact design. It has a stainless steel casing and uses a membrane filter with a 0.2 micron filtration size.
A carry case protects the filter when it is packed in a backpack, side bag or suitcase. The filter lasts up to 1000 liters, depending on water purity. The product is BPA-free.
Do not let the filter freeze. Freezing will at minimum block the filtration function and may permanently damage the filter element.
