LifeStraw Go Water Filter Bottle

The system uses a membrane microfilter to physically remove 99.999999% of bacteria and 99.999% of parasites, including E. coli, Giardia, and Cryptosporidium. The second stage, a carbon capsule, specifically targets chlorine, odors, and organic chemical matter to improve the overall taste of your water.

The membrane microfilter is designed to last for 1,000 gallons (roughly 3,785 liters) of water, which is enough for several years of regular use. The carbon capsule, which handles taste and chemical reduction, should be replaced every 26 gallons (about 100 liters) to maintain optimal performance.

Yes, the bottle is constructed from insulated stainless steel, which is designed to keep beverages cold for extended periods. It functions similarly to a standard vacuum-insulated thermos, making it effective for keeping water refreshing even in warm outdoor conditions.

It is designed for use with freshwater sources like streams, lakes, and tap water. It is not intended to filter saltwater, chemically contaminated water, or water with heavy metals, so you should avoid using it in those environments.

When the membrane microfilter reaches its capacity, water will stop flowing through the straw, signaling that it is time for a replacement. The carbon capsule should be replaced sooner if you notice a decline in taste or an increase in chlorine odor.
