Human beings can survive without food for some weeks but they cannot survive without water for more than three days. This is because every living cell in the body requires it to perform vital functions. This is why to is so important to have portable water purifiers for survival. This is more important than any of the other items required.
Drinking from sources that could be contaminated without purifying can make the difference between life and death. Most of the lakes and rivers of the world suffer from some form of contamination, even small streams that may look clear. Sewage effluent, parasitic worms, animal waste and industrial pollutants are just some of the contaminants. Serious illnesses can be contracted when drinking from a contaminated source. Particularly if an individual is in a remote area, far away from any medical help, this can prove fatal.
Purification of water can be attempted in various different ways. Boiling is often used and this does kill viruses, cysts and bacteria. It does not deal with noxious chemicals and dirt, often having a foul taste. Filtration is often used too and this can be more or less successful, depending upon the efficacy of the filter or filters used. Using chemicals or UV lights are other options.
When buying a device, it is very important to read any information given about it to see how effective it will be. There are those that not only eliminate viruses, bacteria and protozoa but noxious chemicals and most of the dirt particles and foul taste too. One that offers the most comprehensive contaminant removal is obviously best.
Considering the size and weight of such a unit is also important. Considerable distances may be covered and a unit that is large and difficult to carry is not advisable. Fortunately, there are many compact units on the market today that offer great convenience. The fact that they are compact does not mean that they are unable to produce the necessary gallons of water.
When it comes to surviving in the face of some threat, one has to consider the time it may take to purify. In such a situation one may find it necessary to keep on the move. It may be difficult to stay in one spot for a long period of time.
It is also important to find out how easy it is to use. These units work in all sorts of different ways, including use of a manual pump.
