Many walkers use a hydration bladder stashed in a rucksack with a feeder pipe that they drink from while on the move. You could just filter the water before putting it into the bladder, but a more practical alternative is to fit this inline filter to the bladder’s feedpipe so the water is filtered as you suck it through the system. The Pure Hydration Aquasak Inline Filter is designed to work with standard hydration bladders from CamelBak, Source and Platypus as well as others. It’s easy to fit, is very light and relatively cheap. But once the filter reaches the end of its service life the whole unit needs replacing. While it works well as part of your hydration system, it can’t easily be adapted for other filtering requirements, so you may end up having to buy another purifier to filter water for campsite purposes.

The Pure Hydration Aquasak Inline Filter is a useful option for use with a hydration system, but it’s far less versatile than standalone water purifiers.
