When it comes to survival. Your life falls under the rule of 3’s. Statistically most humans can go 3 weeks without food, 3 minutes without air, 3 hours without shelter in harsh conditions (keeping your core temperature regulated), and 3 days without water. Being you’re not running out of air anytime soon unless you are drowning or being choked, and saying you’re body temperature is not in danger, that makes water your top priority in a survival situation.

Through hydration bladders like the Camelbak. It definitely makes carrying a lot of water much easier. However, what happens when you run out and have to resupply? That my friends, is where the infamous LifeStraw comes into play. The LifeStraw is a water filtration system in the form of a simple straw. Simple right?


The LifeStraw was basically the first of it’s kind made by Vestergaard. Since it came out there have been numerous other straw filtration systems and add ons created for them. Such as the Sawer Mini, which has great reviews as well. Vestergaard has also made some great improvements overtime. They released the LifeStraw Mission, which filters MUCH more water, to the tune of 4755 gallons and features a large bladder. If you want a more “on-the-go” option, check out the LifeStraw Go. It features a nice water bottle so you can fill up, and keep moving. And if you have a long term camp established you would want to get the LifeStraw Family edition.


The following specs are for the standard LifeStraw.


  • Lets you drink directly from streams and lakes or from a bottle
  • Uses advanced hollow fiber membrane technology to filter up to 264 gallons or 1,000 liters of water to 0.2 microns
  • Removes 99.9999% of waterborne bacteria, including E. coli and salmonella
  • Removes 99.9% waterborne protozoa, including Giardia and Cryptosporidium
  • Reduces turbidity (muddiness)
  • No aftertaste: LifeStraw® doesn’t use iodine or iodinated resin chemicals and is BPA-free
  • Meets US EPA drinking water standards
  • Ultralight: weighs only 2 ounces or 57 grams
  • Portable: only 9” (22.5 cm) long and 1 inch (2.5 cm) in diameter
  • Requires no electrical power, batteries or replacement parts
  • BPA free and contains no chemicals
  • Raw materials meet US Food and Drug Administration regulations and standards

At the end of the day that rule of 3’s continues. It’s crucial to be redundant in your gear to ensure you have options. When it comes to fire and water, I need to have 3 methods on me at all times. The saying goes, 2 is 1, and 1 is none. So I triple up on fire and water purification methods.

There’s a ton of ways to purify water. Such as bandannas, solar stills, boiling it, etc. It would be wise to pick up a good survival field guide such as the SAS Survival Guide so you always have some handy information available.
