Familiarity: I've put it through the wringer
This filter is awesome! I have been using this for a couple years and it still is working great. To help make it flow a little faster get the water down the tube to the filter and once the filter is wet it will start flowing a lot faster. Grab the water, hang it up, and let it flow! Then go set up your tent, grab your snacks and relax.
