The 7 Best Survival Water Filter Review

Where there is water, there is life. Small wonder then that people the world over are fighting to preserve this most precious of natural resources. Without clean, fresh water, the planet is doomed.

The earth’s surface is covered with undrinkable salt water, and the rest is found in lakes, rivers and streams. This water is largely contaminated with chemicals and micro-organisms. If you’re in the wilderness, you’d have to weigh your options carefully as drinking water like this could make you ill.

You can Directly from the Water Source

For scenarios like this, there are a number of very effective, lightweight, portable survival water filters to look at which can save your life. Some of the straw-like type filters have a built-in element that allow you to drink directly from the source.  Most filters have an internal cartridge that has microscopic pores that catch debris and bacteria. Over time, they will need to be replaced.

Some features to look for in a survival filter include, among others:

  • lightweight, compact and portable
  • filters which are cable of filtering out the smallest contaminants
  • durable
  • meets water filtration standards set by the EPA

Yes, there may be water to be found everywhere, but it may not be drinkable Synthetic solvents, pesticides and plastic residues are also found in the water we drink, and fluoride, chlorine and chloramine are added to our water to make it “safe” to drink.

Whether you find yourself in a city emergency scenario, or you’re lost in the wilderness, without clean water, you quickly start to see the signs of illness and dehydration. The need for water is greater in hot climates when the body loses water quickly through perspiration.

There are many of these water filters on the market – some wonderfully affordable and simplistic while others are more sophisticated and costly. Each one comes with their own set of pros and cons.

Here, we look at different survival water filters:
