The portable water filters are also known as backpacking water filters/ hiking water filter.
What to consider when buying a portable water filter
When traveling, you can’t manage to carry water that will satisfy all the days that you are out.
You should first know where you will get your water for drinking. Remember every water source has its contaminants.
If you are traveling in areas near agriculture land that water has contaminants like pesticides, herbicides, and other chemicals.
Some areas have water that is muddy, salty, and water that has sediments and silts.
Other water sources have contaminants such as bacteria, viruses, and cysts.
Weight and Size
When you are traveling, you can’t manage to carry a filter that is heavy or large that is not easy to pack. Choose a filter that is light and small to pack in your bags.
When buying a portable water filter consider how long it will take to filter water. The shortest time the filter will purify the water the better.
Method of filtration
There is a different method to filter water, and each method filters specific impurities.
We have processes such as oxidation/ chemical (bacteria and organisms), carbon (small particles), Reverse osmosis (large particles), and Ozonation (bacteria, cysts, and virus).
For instance, your water source has virus contaminants; these are rotavirus, Norwalk virus, Hepatitis A, and Norovirus purification method needed reverse osmosis or ozonation, chemical process, and ultraviolet light
If your water has bacteria, these are salmonella and E. coli you need reverse osmosis or ozonation, chemical process, and ultraviolet light
There are water sources that have protozoan cyst these are Giardia lamblia and Cryptosporidium the method used to filter is the ozonation chemical process and ultraviolet light.
Other impurities that are found in water are heavy metals, sediments, mud, silt, large or small particles they require carbon or Reverse osmosis to filter them.
Effective against which impurities
Every water source or every place has different water contaminants when buying a portable water filter you should know which dirt it removes in the water.
All water filters have a lifespan their last from one month to one year When buying a portable water filter consider how long the cartridge will last and how many gallons of water will make it filter.
