A human can go for more than three weeks without food, but water is a different story. More than half of the body is made up of it and every living cell needs it to keep functioning properly. After three days of not drinking, the body starts to shut down. This is why when they have no access to an uncontaminated supply, they need portable water purifiers for survival.
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.
There are several different methods that can be used for purification. Boiling kills bacteria, viruses and cysts. However, it does not deal with toxic chemicals, dirt, sediment or a foul taste. Filtering is another method and various kinds of filtration can be used. The results of filtration vary considerably, depending upon the type of filtration used. Another method is to use chemicals.
When considering purchasing such an item, one of the most important factors to consider is exactly how many of all the pollutants it deals with. Some manufacturers will advertise about how effectively bacteria and viruses or dealt with but neglect to mention toxic chemicals. It is best to go for one that deals most comprehensively with all contaminants even though it may be more costly.
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.
Another factor to bear in mind is time. A treatment method that takes too long will not be suitable. Individuals often need to drink as they move when under threat. They might not be able to stay in one place for the time required for certain treatment methods.
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.
