“It all started with the issue of safe water. Which should never be an issue.” LifeStraw was started on the idea of helping provide safe drinking water for people in developing countries who don’t have water piped in from municipal sources or other access to safe water. While this still remains the mission of LifeStraw, their portfolio has expanded into other products such as the LifeStraw Steel and the LifeStraw Go, both of which we had a chance to test out.

LifeStraw Steel

The LifeStraw Steel is the upgraded version of the original LifeStraw. The Steel is now equipped with a durable stainless steel housing that encapsulates a 2 stage filter. It has removable protective caps on both ends of the straw for easy storage.

The 2 stage filtration process uses a replaceable activated carbon capsule that helps reduce bad taste, chlorine and organic chemical matter for up to 100 liters. The other stage uses advanced hollow fiber membrane technology (0.2 microns) to remove waterborne bacteria and protozoa for up to 264 gallons or 1,000 liters.

LifeStraw Steel Expanded – End Cap, Carbon Filter, Stainless Steel Fiber Filter Tube and Cap


I tested and used the LifeStraw Steel mainly for trail running. It is extremely light weight and so portable that it slides into any running pack or hip pack.

Before using the LifeStraw for the first time or after a long time in storage, it will need to be primed. Which is easily done by holding the filter vertically in the water, with the water half way up the filter, for about 30 seconds. This helps get the membranes moist and make it easier to pull water through.

It may seem strange to some people to stop and drink from a river, lake or pond, but remember that is how we as humans used to do it before plumbing and plastic. Once the Lifestraw is primed it is as simple as drinking water through a straw (see what I did there). Drop the carbon filter end into a stream and enjoy the freshly filtered water. I tested water from three different sources, multiple times; a lake, a pond and a flowing stream. Each time the water tasted as fresh as bottled, no after taste from the filter or the water and it was even chilled by nature.

Cleaning and Storage

After every use, the LifeStraw needs to be back flushed. This is done by blowing a breath of air back into the mouthpiece to purge all remaining water trapped in the filter. You can also suck in water and then blow it back through the filter. This helps remove any air that might be trapped inside. For storage it is best to leave the caps off until the LifeStraw fully dries. Once it is dry, cap it and store it until your next adventure.

LifeStraw Go

Not interested in kneeling down to drink from a stream? Lifestraw has a solution for that, in the form of the LifeStraw Go.

LifeStraw Go Available in 5 Colors

The Lifestraw Go applies the same 2 stage filtration process as the LifeStraw Steel, all contained inside of a convenient 22 ounce (650 ml) refillable BPA free water bottle.

Bottle, Fiber Filter, Carbon Filter and Flip Top Cap

The process is just as simple as you might be thinking. Unscrew the lid to the water bottle, dip the bottle in a river, screw on the top and you are ready to quench your thirst. This is a simpler and quicker process than lying down or kneeling with the Steel, however not nearly as small or portable.

A couple of things to note about the the LifeStraw filters. They cannot remove salt and cannot be used on sea water, ocean water or brackish water (salt water and fresh water mixed together). The LifeStraw won’t last forever, it needs to be replaced when the flow rate starts to decrease, and eventually stops pulling water through. You can increase the lifespan by cleaning the LifeStraw after each use. It is also important to change your carbon capsule every 3 months, after the first initial use to ensure that the first stage of filtration is working well.
