LifeStraw water filters and purifiers make contaminated water safe to drink. Specific LifeStraw products have been designed to best serve specific consumers including outdoor enthusiasts and travelers, and for emergency preparedness. LifeStraw products for Specific public health use are designed for people in developing communities where there isn’t direct access to safe water, and for victims of natural disasters.

The evolution of LifeStraw has been a remarkable journey. It started in 1994 when the Carter Center approached LifeStraw’s parent company, Vestergaard, to develop a filter that could remove Guinea worm larvae from water it was contaminating. Vestergaard designed a cloth filter but then evolved it into a more effective pipe form in 1999. Today, more than 37 million LifeStraw Guinea Worm filters have contributed to the near-eradication of the disease.

Inspired by the impact of the LifeStraw Guinea Worm filter, Vestergaard worked to develop a product that could filter out virtually all of the microbiological contaminants that make water unsafe to drink. The result was LifeStraw technology, introduced in 2005 as a personal “straw-like” filter. In 2008, LifeStraw technology was adapted for in-home use and the LifeStraw portfolio has continued to evolved to include the high-volume LifeStraw Community purifier for institutional settings like schools and clinics, the LifeStraw Go refillable water bottle and LifeStraw Mission, a high-volume, collapsible bag ideal for campsites, group hikes and expeditions. Today LifeStraw is used in water products and projects in more than 64 countries around the world.

The LifeStraw removes 99.9999% of waterborne bacteria, including E. coli, and 99.9% of waterborne protozoa, including Giardia & Cryptosporidium. LifeStraw also reduces turbidity, filtering down to 0.2 microns.

The LifeStraw can filter up to 1,000 liters. This would mean, if you used the LifeStraw every day, for all of your drinking water, it will last for approximately one year. If you just use it for travel and outdoor activities, it will last much longer than 1 year

The flow rate of your LifeStraw will decrease, and then stop pulling water through once it reaches the end of its life. You can increase the lifespan by cleaning the LifeStraw after each use. The great thing is, you can never drink contaminated water from a LifeStraw; when the water stops flowing through it, you know it is time for a new one!

If your LifeStraw has been used, and is then exposed to freezing temperatures, water inside can freeze and crack the filter. You may not see these cracks, so we recommend never letting it freeze once it’s been used. When camping at high elevations or freezing temperatures, be extra careful not to let it freeze.

Yes it is BPA free and completely safe to drink through.
