Hollow Fiber Technology
GravityWorks filters are made of hundreds of hollow fibers bundled into a single filter. Water flows through the walls of these fibers, leaving impurities behind. The resulting filter provides up to 18 times more surface area than traditional filter media.

GravityWorks filters provide clean water faster than most pump systems, and they make it easier to store, transport and dispense all the water you need. All GravityWorks filters meet EPA and NSF guidelines for the removal of Bacteria and Protozoa, including Giardia, Cryptosporidium, E.coli, Salmonella and Cholera.

One very nice feature is that you can collect water from the smallest of trickles thanks for the zipper opening of the dirty water bag.
The other nice feature is that this system is so effortless. Just hang it up and let it do its thing.
The only con is that it is hard to dry the clean water bag after use/sanitation.
