This light-weight, easy, and low cost blue straw has develop into so ubiquitous that many individuals have began shopping for them in bulk, 5 at a time. However how sensible is the LifeStraw in a possible real-world setting, say, in case your municipality’s water provide was compromised otherwise you needed to flee your own home throughout a pure catastrophe?
LifeStraw Specs and Options
Laura Lancaster
Water filters work by transferring water via very small pores—.2 micron within the case of the LifeStraw—which catches any protozoa or micro organism that could be contaminating the water. There are a variety of mechanisms for transferring water via filters. Outdated-school fashions use pumps. Newer ones use squeeze luggage, or gravity itself. The LifeStraw makes use of suction—which you provide. Uncap the LifeStraw at each ends, plunk the soiled finish into your water provide, and begin sucking water via the clear finish.
The unique LifeStraw can solely be used like a straw, however the Peak Collection straw has a bit extra versatility. The design of the soiled finish means it may be connected to a water bottle, or used with a bladder hydration system. Utilizing the Peak Collection Straw in tandem with a water bottle additionally lets you use it such as you would a squeeze-bag system or a gravity filter.
If that is your first time buying a water filter of any variety, crucial factor to notice is that the LifeStraw doesn’t include an connected reservoir. In case you are on the go in an space the place water entry is restricted, it’s vital that you simply additionally carry a vessel to carry water, such an ordinary disposable water bottle or a Nalgene.
Testing the LifeStraw within the Subject
In a best-case emergency situation, your own home nonetheless has working water, however your native reservoir has been impacted and water should now be handled earlier than it may be consumed. (And everyone knows how boiling water is a drag below these situations.) So my first check was to easily hand a glass of water and a LifeStraw to everybody in my household and see what they thought.
I attempted it out first—I undoubtedly wanted quite a lot of suction to maneuver the water via the filter, but it surely was simple sufficient to make use of. After just a few sips—the LifeStraw was simpler to make use of after each—I handed it over to my husband to strive. “It wasn’t that unhealthy,” he mentioned. “The Peak Collection is simpler to make use of.”
Subsequent up was the three yr outdated. She was excited to assist (she spends quite a lot of time as of late “testing” blankets and pillows in makeshift piles in our lounge), however after giving the LifeStraw a strive for 5 seconds or so, she lifted her head and wailed, “I can’t do it!” Seems the LifeStraw isn’t as household pleasant as I had hoped. “I’m so thirsty!” she continued. Now, this wasn’t an actual emergency state of affairs, so it was simple sufficient to only take the straw out and let her drink the water usually, however think about if it had been?
Subsequent, we took the 2 LifeStraws on somewhat area journey across the neighborhood. The primary cease was a stream working out of a slopey wooded space close to our dwelling. Normally within the fall, there’s a gurgling, fresh-smelling stream of water coursing down this slope, however on this explicit day—after an uncommon stretch of dry climate—there was barely a trickle. Worse, it smelled surprisingly anaerobic—a bit like a pile of compost had gone off.
“I’m not consuming out of that,” mentioned my husband flatly. Honest, however science is science so I used to be dedicated to no less than taking a small sip to see if this was one thing I might be prepared to do in an emergency state of affairs.
It took quite a lot of tries at squatting down (these LifeStraw fashions within the advertisements are clearly extra versatile than I’m) to determine methods to get the straw into the water with out toppling over, however I ultimately received there. The water was…heat…however in any other case tasted OK. Truthfully, I’m attempting to not assume an excessive amount of about it.
Subsequent was the lakeshore. That is an lively lake, in all the most effective methods—summertime is filled with boats and seaplanes and fishermen and swimmers. Nevertheless it’s additionally a large number, with the particles from wartime aircraft crashes nonetheless hanging out on the backside and common sewage overflows that get piped in when it rains an excessive amount of. It’s the type of lake the place you retain your mouth closed while you’re in it, and also you all the time take a bathe afterward.
It was considerably more durable to drink out of the lake than the stream. The light waves made it difficult to get near the water’s edge whereas the rocky seashore was troublesome to search out my footing in. On this situation, I might a lot desire to dip a reservoir straight into the water after which drink from that. However, like with the wooded stream, the water was nice, and I felt nice after consuming it.
What the LifeStraw Does Worst
Whereas testing the greatest backpacking water filters, the Peak Collection from LifeStraw simply didn’t stack up in opposition to the likes of MSR, Platypus, Katadyn, and Sawyer. Each the gravity filter and the squeeze-bag filter (that are utilizing related know-how) turned slower to make use of over time, and the gravity filter ultimately stopped working totally.
However from an emergency preparedness standpoint, the largest drawback with the LifeStraw—each the unique and the Peak Collection—is that it doesn’t filter out viruses. Which means water you drink via the straw may nonetheless be contaminated by norovirus or rotavirus (two viruses which can be chargeable for meals poisoning).
Viruses are tremendous small (a couple of tenth of the dimensions of a micro organism), which is why it’s so onerous for a conventional filter to take away them. There are just a few that use activated carbon (Grayl and Speedy Pure are examples right here), which viruses keep on with (the technical course of known as “adsorption”). This works fairly properly—though throughout our check of the most effective backpacking water filter these tended to clog up considerably quicker than conventional hole core fiber filters, together with the LifeStraw Peak Collection know-how. In addition they aren’t as efficient at filtering out viruses from water coloured with sediment or tannins, reminiscent of my native creek. Another choice is the MSR Guardian, which has pores so small—.02 micron—that they will filter out viruses. However that filter sometimes runs at about $400, which is about 20 occasions greater than a LifeStraw.
What the LifeStraw Does Finest
This is likely one of the least costly water filters in the marketplace, so it’s value contemplating if you’re buying in bulk—particularly within the multipacks. No matter your price range, the low value of the LifeStraw means there’s no excuse to not have a water filter in your house or go bag.
They usually do work as marketed. LifeStraw is accredited by a third-party lab—they even publish their outcomes on-line—to certify that they meet US EPA & NSF P231 consuming water requirements. When used appropriately, you’ll be able to belief the LifeStraw to guard you from the likes of Giardia and E.coli.
Last Ideas
In case you’re taking a look at stocking your emergency preparedness equipment with just a few LifeStraws, it’s value upgrading to the Peak Collection model, attributable to its versatility and (comparative) ease of use. Nevertheless it’s additionally value checking to see if one other of the most effective backpacking water filters may higher meet your wants. The MSR Guardian, whereas costly, is able to eradicating viruses, whereas the Sawyer Squeeze Mini is simply a few {dollars} greater than the LifeStraw, and comes with reservoirs to scoop and maintain your water when you’re on the go.
