Product Description

From the Manufacturer

LifeStraw offers easy access to clean and safe drinking water anywhere!

A Time Magazine “Invention of the Year” winner, LifeStraw is the most advanced, compact, ultralight personal water filter available. LifeStraw contains no chemicals or iodinated resin, no batteries and no moving parts to break or wear out. It features a high flow rate and weighs only 2oz. LifeStraw is perfect for the ultralight backpacker, traveler, boy scout, hunter, and especially for emergency preparedness.

LifeStraw filters to 0.2 microns through the use of hollow-fiber membranes, which are small tubes with even smaller pores. These pores allow water to pass, but prevent contaminants larger than 0.2 microns from flowing through. As you get closer to 264 gallons (1,000 liters), the pores will eventually become clogged with debris and the flow will stop.

LifeStraw is the water filter chosen by leading NGOs for humanitarian relief worldwide since launch in 2005. LifeStraws have been sent to Africa, Pakistan, Haiti, and South America for disaster aid, and a portion of domestic sales support this donation program. LifeStraw has only been available in North America since 2011, when excess inventory has allowed it.

How To Use the LifeStraw Water Filter

Filtering your drinking water could not be simpler. With LifeStraw you can drink directly from puddles or streams, or you may find it easier to scoop water with your wide-mouthed water bottle and drink from it using the LifeStraw. When new, the filter membrane is very dry and must be primed before use. Uncap the top and bottom caps and insert the base of the straw into the contaminated water, being careful to keep the mouthpiece dry. Let it sit for 30 seconds to allow water to creep up the membrane, then take 5 quick sucks to get the water flowing. It takes roughly 3-5 seconds of sucking to start the flow of water through the filter when the membrane is dry.

When finished drinking, blow a breath of air back down into the LifeStraw to purge the remaining water out, shake, and recap. If you drink from murky water and the water flow stops, blow back into it to purge the water and mud from the filter. When you return home from a hiking trip, drink some tap water with the LifeStraw, purge the filter by blowing back into it, and leave it to dry with the caps off.

The LifeStraw will not desalinate salt water, remove dissolved chemicals or minerals, nor remove viruses. If drinking from water which may have viruses in it (e.g. contaminated by human sewage), pre-treat with water treatment tablets. See the included instruction manual for more information.

Additional Features:

  • No after-taste. LifeStraw has no after-taste, since no chlorine, iodine or other chemicals are used.
  • No waiting time. You can drink from your LifeStraw right away. There is no need to wait for water to drip or chemicals to act.
  • 5-year shelf life: Can be stored and used periodically. The shelf life is not reduced if the LifeStraw is used occasionally and then put back in storage.
  • LifeStraw meets or exceeds EPA standards for efficacy. LifeStraw was successfully assessed in laboratory conditions (harsher conditions than what is required by the EPA in terms of turbidity and organic matter), up to 1600 liters (approximately 160% of design life). Independent testing at the University of Arizona showed that LifeStraw exceeds the EPA requirements of LOG 6 reduction for bacteria and LOG 3 reduction for protozoan parasites.
  • Bacteria removed include: Escherichia coli (“E. Coli”), Campylobacter, Vibrio cholerae (“Cholera”), Pseudomonas aeruginosa, Shigella, Salmonella.
  • Protozoa removed include: Giardia lamblia (“Beaver Fever”), Cryptosporidium parvum (“Crypto”), Entamoeba histolytica.

If you camp out a lot, or simply prepared to bug out.....then this is for you. I will be buying more, just for bartering, especially when SHTF.......!

One item you can add to this.....paper coffee filters (cone type) are inexpensive. Place one over the bottom of the water filter with a wide rubber band and it will protect the filter with a lot less cleaning. The Water Filter will last 2X as long and cleaner water to drink!

For the weight, I believe there is no better backcountry water treatment available. The LifeStraw imparts no strange flavors like its chemical brethren, its flow rate is perfectly acceptable for active pursuits, it has no moving parts to break or filters that need replacing every couple of days, and it does all this at a fraction of the cost and weight of other Filter and UV water treatment options. Besides, what other water treatment system has been tested successfully by people on a daily basis in the most contaminated parts of our planet?

Just got back from a trip to Nepal and Cambodia. I used life straw dozens of times. Most notably while I was in the jungles of Cambodia I found myself dangerously dehydrated and my two water bottles were already empty. There was NO SAFE WATER for me to drink. I did eventually stumble onto a well used by some monks. After figuring out how to prime and pump up the water I used the life straw to drink my fill. I was so relieved, I was miles from the nearest bottle of water and I managed to get my drink on. I didn't have to take a risk that would have put me in an awful situation (severe diarrhea) , and it only cost me $25 and the weight of the straw is negligible.

In fact, I've decided that whenever I'm leaving the country to take this guy with me. Why not?

I've Done My Homework. Few have explained why they think it is so good or why it isn't. The idea is great and I have one, but I also have the Sawyer Mini Filter, from Amazon, for the same price. It is half the length, same 2oz weight, but also requires a supplied syringe to back flush. It filters more contaminates (safer) and filters 100,000 gallons vs 264 gallons for LifeStraw. Filtration is .1 microns vs .2 microns LifeStraw and protozoan parasites (>LOG 6 reduction) -vs- (>LOG 3 reduction) protozoan parasites.
COMPARISONS BELOW:

-LifeStraw-

•Removes minimum 99.9999% of waterborne bacteria (>LOG 6 reduction) and surpasses EPA standards for water filters
•Removes minimum 99.9% of waterborne protozoan parasites (>LOG 3 reduction) and filters to an amazing 0.2 microns
•Filters up to 1000 liters (or 264 gallons) of contaminated water.

-Sawyer Mini Filter-

•High performance filter fits in the palm of your hand, weighs 2 ounces and filters up to 100,000 gallons (30 times more than comparable filters)
•Attaches to included drinking pouch, standard disposable water bottles, hydration packs, or use the straw to drink directly from your water source
•Removes 7 log (99.99999%) of all bacteria and 6 log (99.9999%) of all protozoa
•Sawyer's certified 0.1 micron absolute filter removes bacteria and protozoa at a higher rate than accepted EPA guidelines

When I was putting together 72-hour bags for our family, I had all the bases covered except for drinking water. I researched for a long time before deciding to get these LifeStraws, but we are very happy with them. They are light-weight (only 2 ounces), made of durable food safe plastic, they filter up to 260 gallons of water, and they allow everyone to have their own source of safe drinking water. They've also been proven effective in preventing water-borne diseases in developing countries for years (nearly a million Lifestraws have been distributed in Kenya). They filter out dangerous pathogens like e-coli, giardia, salmonella and cryptosporidium, and make water from any source safe to drink. They are perfect for survival situations, foreign travel, or even just one-day hiking trips. Time Magazine gave Lifestraw the "Best Invention of the Year" award in 2005.

I bought ours directly EarthEasy.com and not on Amazon, and we've used them several times. They can be used to drink directly from any body of water, but to protect the filter from getting clogged, it's best to pour dirty water through a T-shirt to remove dirt and debris before using the filter.

I like knowing our family won't have to worry about safe drinking water if we're faced with an emergency.

This product is hands-down the best filter out there!

I bought mine at Bass Pro Shops for $19.99, but it happened to be one of the older 3 year shelf life straws, which could explain the price difference(Was manufactured in May).

It takes a second to get the water flowing, and its not easy to "blow out" the water as it recommends, but this thing works great!

My favorite feature is that, when it can't filter water anymore, it just STOPS LETTING YOU SUCK WATER THROUGH IT. Amazing, right? No guesswork...just get a new one ever 3/5 years, and use it till it stops working.

Note: Its a little hard to blow water out, but not impossible. If you find yourself blowing and not getting ANY air out, its cause it sealed itself(however that works) and isn't gonna let any more air pass through, you've gotten enough out already. Don't waste your effort trying to get the last few drops out, it won't happen.
