Title: Can't get Charcole Specs to purge...Even with Clean Water
Review: I purchased this Water Filter to go in my backpack so I didn't have to carry water which is extremly heavy. After following directions and purging a couple of liters and watching the initial carbon black junk come out....I can't get the speck of carbon to stop. I'm using Clean Tap Water and have used 10-15 liters of water to purge. The water going into it is cleaner than the water coming out of it...I have contacted Katadyn to see if they will send me a replacement filter cartrage...waiting for their reply. Steve from Oregon
