Gravity Feed Water Filter Spring Roll Field Bag

Spring Roll portable filter! What is it?
The Spring Roll is a portable water bag with ceramic filters that can be filled and hung from a tree. When you need water hang it up somewhere while it drips into a container that way you’ll always have quality water to drink. Take it camping, hunting, or when bugging out in an emergency. Each bag uses two (2) filters. These are a different filter than those used in the buckets.

A Spring Roll contains two ceramic-activated carbon filters with pre-filter socks. They are carefully positioned inside a sturdy, water-proof, food-grade water bag with an outlet for filtered water. All you do is fill the bag with unfiltered water, hang it somewhere to let gravity do the work, and convert it to potable water. No tablets, pumps, or fancy equipment are needed when you use our pristine filtering elements.

Its components are washable for increased longevity, filters are replaceable, and the unit is lightweight and easy to transport.

The Spring Roll can be a perfect solution where potable water is a real issue or concern. Campers and hikers love them and maybe you would want one for emergencies. And some people use charcoal ceramic filters in their houses to make chlorinated water taste better.

Set up and storage:

• Use the threaded straps to hang the Spring Roll from a sturdy support structure such as a tree branch or well-anchored hook.
• From the top opening of the Spring Roll, you can pour up to three gallons of unfiltered water.
• The first time you use a Spring Roll flush it for five to ten minutes before drinking the water.
• Once the filters are saturated and with consistent water pressure clean and safe drinking water will flow at approximately ten gallons per hour.
• When not in use, clean all Spring Roll components before storage and allow them to dry completely to prevent mold and other pollutants from growing.

Cleaning:

• Unscrew the outflow nozzle from the bottom exterior of the Spring Roll.
• Gently remove the filtering unit from the bag.
• Remove the cylindrical plastic encasement from the dual filtering units.
• Remove pre-filter socks and wash gently in soapy water. Rinse thoroughly.
• Ceramic filter domes can be twisted off and rubbed clean with a lightly abrasive material such as fine sandpaper, a scotch pad, or a new dish sponge.
• All plastic parts and the bag can be cleaned with a cloth and soapy water.
• Rinse off, let it dry, and reassemble. This way your Spring Roll will be restored to as good as new!

Contents: A Spring Roll comes with two removable filters, two pre-filtering socks, a protective casing, a hang-able roll-up bag with a strap, 30″ of vinyl tubing, and a cap.

This water filter utilizes a simple 4 Stage process:

• The washable pre-filter socks catch the largest particles and greatly extend the life of the encased ceramic filters.
• The Ceramic filters are made of diatomaceous earth to prevent anything larger than 0.7 microns from penetrating the filter when it is new.
• The ceramic contains silver, which is a natural bactericide.
• The ceramic encases the high-grade Granular Activated Carbon. GAC has a vast pore structure with enough surface area to adsorb numerous organic and inorganic compounds and impurities from contaminated water. Activated Carbon is very reliable eliminating unpleasant tastes, odors, and color.

A unique aspect of ceramic technology is the pore sizes tend to reduce. This is due to the filtrates that build up and block portions of the ceramic wall. Pollutants tend to build up over time and shrink the pores that are tiny and labyrinthine, to begin with. So with use, only the very smallest particles will be able to penetrate the ceramic of the filter, thus making the water cleaner than when the filter is brand-new. Inevitably over time, this will reduce the flow rate, lightly sanding the filter surface prolongs filter life.

It’s important to note our filters aren’t meant to remove viruses due to their nanoscopic size nor are they capable of desalinization. They have not yet been tested for EPA standards, although they have been tested for bacterial removal and have consistently removed four logs (99.99%) of environmental and laboratory bacterial samples.

Bacteria such as E-coli and Protozoa such as Cryptosporidium and Giardia can be effectively removed. In an emergency or outdoor situation, microbiologicals are the most important contaminants to prepare against. This product has been used for years in disaster situations in remote locations with no known recorded illness or side effects.
