ShuRex Gravity-Fed Water Filtration System — 12L Portable Purifier for Travel, Backpacking & Emergency Prep

Overview

ShuRex Gravity Fed Water Filtration System is built for travelers, campers, and emergency kits. The 12-liter gravity bag provides ample hydration for a family or group on outdoor excursions, while a dual-filter core works to address particulates and odors as water moves through the system.

How the filtration works

The core combines a hollow fiber membrane with 0.1 micron pores for fine particulates and a carbon filter to help reduce tastes and odors. Both filters are replaceable, so you can refresh performance as you go.

Capacity and speed for groups

With a 3 gallon (12L) bag, you can meet the water needs of multiple people during hikes, camping trips, or roadside stops. The Duo Filtering Straws design makes it easier for several people to sip water without waiting for the bag to refill.

Materials you can trust

The bag and components use food-grade, BPA-free materials designed for everyday use in the outdoors. Durable construction helps you rely on it across varied terrains and weather conditions.

Versatility for different setups

You can operate the filter straw by itself or pair it with the gravity bag. An extension tube lets you position the straw farther from the water source, and you can even connect to standard water bottles for flexibility.

What’s included

• 12L/3 Gal water bag
• Filter Straw x2
• Adjustable Tree Strap

Real-world use scenarios

Ideal for backpacking trips, family camping, or emergency preparedness kits, this system combines portability with reliable filtration. Picture filling water at a campsite faucet, then pouring filtered water into a bottle for a quick refuel before the next leg of your journey.

Care and replacement

When the life capacity nears its limits, replace the Hollow Fiber membrane (up to 6000 L / 1500 gal) and carbon filter (up to 300 L / 80 gal) to maintain performance. Following simple cleaning and storage tips helps prolong life.
