So why bother with a water filter? Surely you can just carry a water bottle with you and fill it up before your adventure? Whilst this is true, what happens if that water supply runs out? What happens if you drink your bottled water and have underestimated your water allowance?

In situations like these, the best water filters are invaluable. They allow you to continue using clean water for washing and drinking, even if your original supply has run out. You can simply scoop some water from a stream or river, use the filter, and use the water as usual!

But why can’t you simply drink natural water without a filter? You can, however it is best practice to use a filter. Stream water or lake water can transmit the following water-borne infections – e coli, salmonella, giardia, and dysentery.

In short, investing in a filter is just the sensible thing to do to prevent any of the above!
