Lifestraw

Recommended Posts

Any of you folks have knowledge and experience using Lifestraw ?

I've heard a lot of good things about it, but when I look at the specs for it on the REI web site, it only talks about filtering out biological contaminants (like bacteria or parasites).

That's great, but how does it do in waters that may have chemical contaminants or heavy metals?  I do most of my camping and hiking in Texas where quite a few of the waterways where I like to play are listed by the state's environmental quality commission as contaminated with appropriate health advisories against eating fish caught in those waterways.  If the fish can be contaminated with PCB, dioxin, mercury etc., then I assume I don't want to be drinking the water there myself, even with a Lifestraw.

Is there a filtration device that can handle chemical contamination?

The MSR Sweetwater Microfilter states that it does heavy metals. $200

I carry a Katdyn Hiker, which has a carbon core that is very good at removing taste and smell issues.  It easily handles bacteria and protozoa, as well as chemicals. One one of our regular backpacking/kayaking routes there is a small camp with a non-potable faucet.  The katdyn filter completely removed the strong sulfur smell and taste that a Sawyer filter did not.  No need for drops as well, although I also carry a SteriPen.

Very few filtration devices can handle chemical contamination or viruses.  I wouldn't worry too much about occasionally drinking that water with the fish advisories. Why? Biomagnification.  The fish have high concentrations of those chemicals because they are towards the top of the food chain. The concentration of the chemicals goes up each level of the food chain that the creature is on.  The water itself probably doesn't have high levels of those contaminants.  

 

That said, for biological filtering I would recommend the Sawyer mini over the Lifestraw.  They are about the same price, but the Mini can filter much more water, and has much more versatility. In addition, it has a smaller pore size than the Lifestraw (which means it can filter out smaller biologicals).

Thank you, perdidochas.  I looked at the reviews on that Sawyer Mini and am impressed.  While it looks a bit more complicated than the Lifestraw, the increased flexibility of the device coupled with a significantly longer lifespan looks like a winner to me.

I see that REI sells the Sawyer Mini as well as Lifestraw, both for the same price.  I'll be buying the Sawyer filter....

You are welcome. I've researched it some, and came to that conclusion.  I have two Minis (bought for me as gifts, never used, but sometimes carried), and a Sawyer 3-in-1, which is an older model (pre-Squeeze) that I got on sale at the Scout shop. I've had good luck with the Sawyer.
