What are the best portable water filtration systems for UK backpacking and camping?

When planning a backpacking or camping adventure, reliable access to clean water is a key concern. The human body can only survive for about three days without water, which makes the need for a portable water filtration system paramount. In the UK, despite the apparent abundance of fresh water sources, waterborne pathogens like bacteria and viruses still lurk in unsuspecting streams and rivers. The right water filter can be a lifesaver, removing these harmful contaminants and ensuring you have safe, clean water to drink. In this article, we'll delve into some of the best portable water filtration systems available for UK backpacking and camping.
