Nescessary for filtering!

Just because you have a Steripen doesnt mean you will have clean-debris free water. This filter is essential, in fact it should come with the Steripen standard (that crucial). It screws on top of your wide mouth Nalgene bottle as you dip it into a stream lake etc... and the nasty silt sand etc... get stuck outside the filter and not inside the water you are about to zap with UVC light. Then as the water bottle is filled with untreated water pull out the mouthpiece portion while leaving the filter screwed into the Nalgene and add the Steripen then turn the Nalgene upside down and rotate for 90 seconds and blam fresh water without debris and killed microorganisms. The one thing this and the Steripen do not do is eliminate color from the water. So hopefully that dosent bother you, but most streams and lakes you get pretty clear water anyway.
