The 6 Best Camping Water Filters

Drinking water is one of the two things required to sustain life. Being able to access clean water while camping or hiking for extended periods of time may get tricky. Depending on your camping situation, you may not be able to bring in all the drinking water you'll need. The recommended amount of water a single person should drink every day is about a half-gallon, and that weight can add up quickly. When you are active and expending energy, such as you do when hiking to and from a campsite, you need to increase that amount. How can you enjoy a relaxing hiking and camping trip and still have the energy and space needed to bring all that water around with you at the same time?

The solution is you don't have to take all the water you need. Instead, you can invest in a good camping water filter to ensure you have clean drinking water whenever you need it. Being able to utilize naturally occurring water sources as you work your way through a trail is a game changer for saving time and space, as well as providing peace of mind that you can drink from any water source safely. What are some essential features to be on the lookout for in a water filter? Continue reading to find some helpful tips.
