Nothing is more important when trying to survive than water. Our bodies are made up of about 60-80 percent of this precious liquid and cannot function properly without it. When long periods are spent without access to a drinkable supply, individuals require portable water purifiers for survival. Without a source of drinking water, no other fancy equipment is relevant.
A large percentage of the lakes, rivers and streams in the world are contaminated, even those that may look clear. Sewage effluent, animal waste, parasitic worms and noxious chemicals are just some of these pollutants. Taking even one drink can be deadly due to various illnesses that can be contracted. This is particularly dangerous when in remote situations where medical help is unavailable.
A number of different methods such as boiling, filtering and use of chemicals are used to deal with bacteria, viruses and other problems. Some of these methods are more effective than others and a combination of methods may be used too. Boiling definitely helps to get rid of viruses, cysts and bacteria. However, toxic chemicals, dirt and bad taste are not removed. Filtering varies considerably in the results obtained, depending on the type of filter used.
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.
The size and weight of such a unit is another important consideration. This is particularly important when covering long distances. In such a situation, one must look for the most compact, easy to store unit. Big is not always best and some of the most compact units on the market today are perfectly capable of offering comprehensive contaminant removal and supplying the quantity required.
Some of these units may take a considerable amount of time for purification. This has to be born in mind in survival situations when the individual may have to be able to drink while on the move. Of course if one is able to stay in one spot for a considerable period, this is not a problem.
One needs to make sure that the unit purchased is easy to operate. This is also important in an emergency situation where a unit that is difficult to operate may cause fatal delays. Some are very ease to use and are operated with a manual pump which pushes the water through various filters like ceramic, glass fiber and carbon until it is safe to drink.
Many suitable units are available today from local and online stores. Shopping for such self-contained units online offers convenience and the ability to compare many different types and their prices as well as read reviews written by customers. Selecting the best possible item one can afford with regards to effectiveness, weight, ease of use and other such factors is vital in a survival situation.
