Most of us take water for granted. Go to the tap, turn it on and you instantly have hot or cool water that you know is safe. What if that weren’t true? What if a time comes that you turn on the tap and nothing comes out or, worse yet, you find yourself in a place with no taps? Finding yourself without a water source is not as farfetched as you might think.

The Truth About Water
We are almost as dependent on water as we are on air. You can only live for about 3 minutes without air. Without water, you will start to suffer the effects of serious dehydration in about three days and will probably die in just a few days more.
Water is everywhere, it seems, except in the harshest environments. There are places where available surface water is non-existent, but the likelihood of finding yourself in a survival situation in one of these places is remote.
Think about Water
Stop and think about water for a moment. If we turn off that ready supply that we get from our municipal water systems and take out the possibility of getting water easily from a well because the power grid is no longer operating, what are your options?
I know there is water in several ponds in the parks around our city. We don’t have the option of large lakes or rivers nearby. Given a situation in which you need to move from one place to another to find a safe haven, how will you manage to stay hydrated and healthy?
Drinking straight from most ponds, rivers, lakes, or collected rainwater is an invitation to some serious health risks. Not something you want to find yourself facing, given the absence of professional medical care in these instances.
You may simply be deep into a wilderness experience and need to replenish your drinking water supply. The question remains, how do you deal with the need for a constant and daily supply of purified drinking water? There are some options, but each seems to have its own set of pros and cons.
Check out our article on water purification myths.
Water Filtration vs Purification
There is a huge difference in filtration vs. purification. It is a difference that could affect your ability to survive or maintain your health. Don’t be fooled by some advertisements. Not all survival water systems are the same. This is one of those situations that you want to outfit your bug out bag or survival kit with the best possible equipment you can buy.
By definition, a filter or a filtration system is designed to remove particles from the water. Filters don’t have any capability of rendering bacteria or viruses inert. Filters are mechanical devices that are rated by the largest particle that will pass through the filter material.
Filters are typically rated in microns. A micron is 1/1,000,000 of a meter) For comparison sake, a human hair is about 181 microns for the coarsest hair. The E-coli bacteria measure about 1 micron in diameter and about 2 microns in length. E-Coli are rod-shaped bacteria, so to be sure that you are safe, your water filter system would need to filter down to 1 micron to prevent your drinking water from contamination.
Viruses pose an entirely different problem in water. Viruses are typically much smaller than either protozoa or bacteria. Many of the most dangerous viruses range in size from .001 to .3 microns in size. The smallest viruses will pass through most commercial water filters unimpeded.
Additional steps must be taken when filtering water from sources that may be virus contaminated. Filters or purification systems that tout themselves capable of removing viruses must have laboratory testing to prove these assertions, and you should ask for a copy of the lab test results.
Water systems that are advertised as purifiers or purification systems must also have some means of rendering viruses and bacteria inactive. This can be accomplished in several ways.
- Mechanical filtration – Some filters are rated for sizes of particles that will catch and trap the most dangerous viruses or bacteria. Reverse Osmosis systems are a type of mechanical filter that will remove the vast majority of dangerous organisms from water.
- Chemical actions – There are several methods of rendering living organisms in your water source inert. Specialty water treatment tablets are available through many outdoor and recreational stores and websites. One of the most common methods of chemical treatment is the addition of chlorine to a water source
- Physical treatment – One of the most effective means of making your drinking water safe is to boil it. Raising your water to the boiling point and letting it stay there for a few minutes will kill any dangerous contaminants in your water.
Which do you need?
The answer to that question depends a lot on your location. If you live someplace where naturally occurring springs are common, or you can access meltwater directly from a glacier, you are probably safe with almost any filtration system on the market. However, if you are sourcing your emergency supply of water from any other source, it always has the possibility of contamination from a variety of sources.
I am a bit of a redundant person. I don’t like to depend on one tool, source of supply, or water purification system. My motto has always been, “One is none, two is one.” Let’s look at some of the options for survival water purification and filtration and how they can fit into your survival or bugout plan.
What are the Advantages of Straw Water Filters?
Straw water filters have some characteristics that make them pretty great to have on hand. Most of them are quite affordable, so really, anyone can pick one up and be prepared.
Their small size makes them incredibly easy to pack in a bag, a vehicle, or even in a pocket. This allows them to be carried almost anywhere with ease.
Also, straw water filters are extremely easy to use. Their size and ease of operation mean anyone can start using one without much of a learning curve.
What are the Disadvantages of Straw Water Filters?
Straw water filters can be rather good at what they do but they are not the end all be all for obtaining drinkable water.
Some straws have limited capabilities of what they can filter from a contaminated water source.
Like the above, straw filters do not filter everything harmful from a contaminated water source. So, they should not be used without that consideration.
If water straws are not taken care of, there is potential for them to become dirty and not as safe to drink from.
Lastly, some straw filters are constructed from questionable materials and put together in questionable locations. Both parameters should be thoroughly researched before purchasing to ensure you get a filter that does what it is supposed to do.
How do you Properly use a Water Filter Straw?
Many water filter straws need to be primed first. All this means is that one end of the straw needs to sit in a water source until the filter becomes saturated. After priming, simply draw water through the mouthpiece to drink.
Some straws also require the filter to be backflushed with clean water after every use to keep it as clean as possible and to prolong the filter’s life span.
Don’t get Caught Thirsty
In a survival situation, the worst thing you can do is to ignore your need for clean, pure water. Without an adequate supply of filtered water, your body will soon begin to suffer from the effects of dehydration, degrading your ability to function at the peak levels needed in an emergency. This can quickly put you into more trouble and endanger those who may be depending on you.
I recommend that everyone have the means to filter water in their bug-out bags, their three-day packs, a get home bag, and somewhere in the house. Ideally, each member of your family will have a personal filtration system, and a larger system should be kept ready in the home for an emergency.
