Platypus GravityWorks Pouch and Filter

Product Name
 
The GravityWorks water filter system is a backpackers and hikers delight... and great for anytime you need to treat and filter water.
 
The system combines two Platypus water pouches with an inline filter.

To use you simply fill up one of the reservoirs with the dirty water from a river, lake or other water source and let gravity do the work of moving the water down through the filter into the second pouch with all of your clean water.
 
One good tip with this system is if the filter gets clogged (and it does happen with these style water filters since they are designed to filter out microscopic organisms) you can simply squeeze the clean bag to backflush the line and filter.
 
The real benefit of the GravityWorks over typical manual water filters is it uses gravity and has simple pieces. And unlike nearly all other water filters on the market, GravityWorks does not have any mechnical or moving parts that can break. You can pickup replacement inline filters inexpensively.
 
In the field this  filter can be adapted to other things you may have on hand. Simply plumb the bottom of a bucket and you can hook the hose and filter up and let gravity do the work for you to filter gallons of water at a time.
