In my quest for light weight camping items I found something that has peaked my interest.
A 3 oz water filter that is good for a million gallons of water. YEP.. Sawyer grantees it for a million gallons of filtered water.
The pouches are .5L , 1L and 2Liter pouches they along with the filter weight 3 oz total.
When you get to a water source and don't want to filter the water then you fill the pouches , put them in your pack and later in camp , filter the water into your water bottle of just drink directly from the filter when it is attached to one of the pouches.
One report about the filter I read the person figured out that this system would replace 20 normal filter replacements on the others where you eventually have to replace the filtering cartridge.
Here is there web site. ( It's the PointONE System. )
