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.
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.
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.
Once effectiveness has been established, another consideration is the weight and size. A device may be effective but may be too bulky and difficult to transport. One that is compact and easy to store is preferable, particularly when considering that long distances may need to be covered. There are small compact devices on the market today that have the ability to process up to 500 gallons or so before the filter needs changing.
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. There is no point in going for the most expensive product on the market and then find that operating it may be difficult, especially in an emergency. Reading online reviews may be helpful in finding out how other individuals have experienced using a particular unit.
These units are widely available, including from many online sources. Making a choice can be difficult but bear in mind that this decision may be a life or death one. Do not compromise on effectiveness for the sake of price. As long as you take all the factors into consideration such as effectiveness, size, weight and ease of use, you can choose a unit you feel does the job properly and suits your budget.
