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 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.
Some filtration units consist of as many as three different filters with a carbon filter at the core. This ensures that as many contaminants as possible are dealt with and the end product is not only safe but pleasant to drink. There are those that are easily operated with a manual pump. Ease of use can be vital in an emergency situation.
There are a vast number of units on the market today. Purchasing from an online store offers the chance to compare all the relevant details relating to such a unit. It is important to examine all the information given such as what it is effective against, size, weight and exactly how it works. Prices can also be compared. When selecting such a unit, it is worthwhile spending the most one can afford as it could be a life saving choice.
