When you go camping or hiking or even in an emergency situation, there are many chances that your water is not as pure as you would like it to be. This is the reason you will need a water filter and the article below aims to help you by making a thorough Sawyer water filter review. But first, let us see why we need water filters in the first place.

Today, survival has become not only a common leitmotif in TV shows, but also a part of a reality that can strike us anytime and that should concern each one of us in the most serious way. A catastrophe may break out any moment: a war, a final energy crisis or a series of devastating natural disasters. All these negative factors can always throw mankind 1,000 years ago.

The risk of such a doomsday scenario is, as you can tell for yourself, becoming bigger. It is therefore imperative to know even basic techniques and methods of survival in nature. This knowledge may also help you if you are a trip lover and you are constantly finding your way out of the crowded cities to wild and peaceful places.

Equally important it is to know how to use a number of objects that can help us thrive the hardships and obstacles of the wilderness. Treat them with the greatest respect. They may appear as common objects to you, but if you take a moment to analyze them, you will discover how helpful they can be.

These are simple items found in almost any home, if you will search for them. But they are very important as they make the difference between life and death and between hope and despair.

The importance of water filters

Probably the most overlooked items in a survival kit is the water purifiers which are actually the biggest help of someone caught in hostile natural environments where water sources are either polluted or ruthless swarm of bacteria and viruses. Yes, this is true! Have you ever seriously wondered how important is water for your own life?

Filters for purifing water

The lack of air leads us to death in agony after just 3-5 minutes. The next vital element is water. Without water you may survive up to 3 days (that’s just if you’re lying and do not do any physical activity after which sweat occurs). If you are in deserted areas or even in a temperate climate area during hot summers the lack of water can kill you even after a day without proper hydration.

Water contamination

Water may be contaminated by two kinds of agents: organism contaminants or chemical ones.

Organism contamination

There are a lot of hazards that can be found in water. Organisms are very small, with a size in the range of microns. Here are some examples:

  • Viruses (hepatitis, rotavirus)
  • Bacteria (100 times larger than viruses. 90 % of the bacteria are harmless to humans, some of which are even necessary, but the remaining 10 % are dangerous, like Typhoid or Cholera)
  • Protozoa (very simple organisms, they cannot be seen with naked eye and some of them can form cysts)
  • Cysts (these are micro-organisms that can survive in harsh conditions, in water of fecal materia. You may find Cryptospyridium or Giardia amongst them)

Chemical contamination

In this case, the water is contaminated with metals (like mercury, lead, arsenic) or with nitrates/nitrites. They appear due to human activity. You should pay attention while you are in mining areas as the water may be infested.

Chemicals must be filtered somehow as they cannot be destroyed as easy as the organisms.

Water purification

There are few ways you can purify the water in order to be able to drink it.

Boiling the water may kill the organisms. Along with an increased altitude, the water will boil at lower temperatures so you have to wait more until it is ready and good for drinking. Bacteria are instantly killed at 82°C. Cysts are killed within 10 minutes of exposure to a temperature of 70°C.

Boiling water

Chemicals are not eliminated by heating the water!

Chemical treatment means using chemical agents to kill the micro-organisms in the water. The best known are purifying pills. Basic used substances are chlorine and iodine. Do not use chlorine or iodine directly unless you know exactly the dose. It is recommended to buy pills especially created for this purpose.

Distillation and evaporation means to capture the vapors which are then converted back to water. This can filter out certain chemicals.

Filtration is done by passing the water through filters with different material densities – the denser the material, the larger the number of filtered impurities.

Unfortunately more and more waters are intensely polluted all over the world. They become true “breeders” for bacteria. If you run over water sources you do not know for sure they are drinkable, purifying pills of water filters are the aces in your sleeve. In other words, take care not to miss the water purification devices in your backpack whenever you leave home for a journey in nature.

Evaporation from plants

You may find water filters under any shape, size and price. They may vary from a device that can filter a few liters of water to a small pill that will instantly purify a portable water canister. When you buy them be careful that the pills or filters have the ability to neutralize giardia worms and the protozoa of the genus Cryptosporidium (the protozoa in question causes diarrhea leading to terrible instant dehydration and can be deadly in children). As stated before, they are the most common intestinal parasite in water ponds, lakes and even some springs.

From all the water purifying devices, water filters are the most versatile and reusable. While a pill can be used only once, the filter may last for months.

    I think boiling water is the most efficient way to purify it. But, sometimes fire isn’t available that’s why water purification tablets are a must-have in your Bug Out Bag or backpack.

    • Samuel Funt

      Boiling may be the most efficient way of purifying water, but you should have alternatives in case boiling is impossible at a given instance in time, and purification tablets are a good choice.

  • Ethan Barston

    When I was in the Army we had one of these. It is light, good to carry around and takes almost no space at all. Definitely, a must have for anyone who plans on venturing to wild nature for prolonged periods of time.

  • Thank you, Ethan, for sharing your opinion with us.
