Using the faster flow does shave off pumping time if that's what you need. Switching between the two modes takes just a couple twists and turns. The ceramic prefilter is great for removing sediment in dirt filled water. If that gets too mucked up take off the top and give it a wipe or two and you'll be good to go again. The third stage filter is the active carbon core reducing chemicals and bad taste which is certainly a plus. It screws on to the top of nalgene wide=mouth bottles and can hook up to your Camelbak hose so you don't have to remove it from your pack. Sweet!
