Most people that hike regularly and are always going to different kinds of hiking trails need some kind of permanent and harm free way of keeping themselves hydrated. The available water will be that of the river or lake which cannot be drunk without purification. By using a portable water filter, you can even drink water from a pond. This is because water filters remove all the pathogens and other harmful metals that are present in groundwater. Not just that, by keeping a portable water filter, you’ll have an unlimited supply of clean water as most of these can purify up to 2000 gallons of water.
No matter how regularly a hiker goes into the wilderness, they can never carry more weight than they usually carry. This is why they need portable water filters because water bottles will just add on to the weight that they’re already carrying in their backpacks. For hikers that cannot carry even a little more weight, the survivor micron filter is the best. It only weighs 3.5 oz. and can be carried around in your pocket. There is also the Sawyer mini filtration system that cleans all of the harmful chemicals and can just be screwed on top of any bottle for use. These water filters not only purify water of bacteria, protozoa and other chemicals, they also remove any sediment that might be present in the water so that you have clean drinking water.
It is not advisable to set out on a hiking trip without proper arrangement of water. This can lead to dehydration due to which you might have to stop halfway and call for rescue. This is very likely as dehydration can cause unconsciousness and many other things due to which you won’t be able to continue.
