If you are travelling a lot around the world and never certain whether the local water will be safe to drink or not then getting a portable filter can be a great solution.
Not only will you be able to drink the water safely but it'll also taste a lot better too! If you are going to be camping around the world then even seemingly simple this like cleaning your teeth in the morning can become difficult without clean and safe water.
Sometimes you won't be sure whether the water is safe, and sometimes you'll know it is definitely not.
In either case it pays to be on the safe side by using some sort of water purification system.
What To Look For In A Portable Water Filter Water filters are not all as good as each other.
Some will simply make the water taste better, while others will purify it.
You need to make sure exactly what the filter does and what it doesn't do.
While a filter that makes the water tastes better might be handy, one that makes the water clean and safe to drink is much more useful if you are going to travel the world camping.
You'll also need to make sure that the filter is compact and easy to carry around.
It needs to be convenient as you'll probably b taking it everywhere, you don't want it to become a hassle.
Another important point is how much water the filter will work with before it needs to be replaced.
If you are going to be going away for a long time you may need to take a supply of them to last you the whole trip.
