Uncharted Supply Co. Puribag

Yes, the Puribag Micro filter is designed to be versatile. It features a universal thread that attaches to most standard 28mm plastic water bottles, allowing you to filter water on the fly without using the included bladder.

The Puribag Micro filter is rated for up to 5,000 liters of water. While there isn't a digital counter, you should replace the filter if you notice a significant decrease in flow rate or if you have reached the 5,000-liter capacity based on your usage frequency.

The backpack is designed to be lightweight and durable for outdoor excursions, but it is not a fully waterproof dry bag. It is intended to carry your hydration system comfortably while you are on the move.

The 0.1-micron filter is highly effective at removing bacteria, protozoa, and sediment from water sources. It is not designed to remove viruses, so it is best used with fresh water sources like streams, lakes, or rivers rather than water potentially contaminated by sewage.

The 2L bladder is made from a flexible material, meaning it can be rolled up or folded down to a very small size. This makes it easy to pack away inside your gear when not in use or when you need to save space.

The system is primarily designed for you to fill the bladder with water and then drink through the inline filter. While you could technically use the hose to draw water, it is much more efficient and safer to fill the bladder first and let the gravity or suction filtration work through the hose setup.
