We use these on our annual kayaking trips and although they do a good job filtering your water it leaks back out of the filter when you go to take a swig out of it so water pours down your chin or top. A bit annoying.

Rated 5.0 out of 5.0 by Bob Wohlers ALWAYS Pre-Filter First! Off-Road Safety Academy
If like me, you need to source dirty water containing lots of particulate matter ("Crud"), it is a necessity to pre-filter the water prior to applying any type of water disinfection treatment. Nobody likes "crunchy" Crud in his or her naturally sourced drinking water. Yuck! With the SteriPEN Pre-Filter, your removal of Crud is EASY. With this ingenious device, you can easily source water from a tap, lake, pond, or stream. SteriPEN's Pre-Filter also makes it incredibly easy to use your SteriPEN to disable the genetic code of all the bad Critters that can be found in wilderness water sources. Simply remove the small pre-filter from it's bottle cap and place your SteriPEN down into the water. Many models of SteriPENs will seal against the bottle top's opening. This allows you to turn the bottle upside down and shake it during UV treatment. There you have it… No Crud and complete disinfection. With SteriPEN's Pre-Filter and use of any model SteriPEN, you have a genuine water disinfection "system" that is small, convenient, and trust worthy.
