Description

SteriPEN Pre-Filter

The SteriPEN Pre-Filter filters fits on Nalgene® and other 32 ounce wide-mouth water bottles and filters out particulates and debris. When in use, pour water through the durable 40×40 micron screen filter cartridge to fill the bottle. Then you’re ready to purify the water with a SteriPEN UV water purifier. Remove the filter cartridge from the Pre-Filter, insert the SteriPEN into the center of the filter, flip the bottle, and agitate the water until the SteriPEN indicates the treatment is complete.

I am planning a Spring trip to the Southwest. The rivers will be full of silt - sand and some very fine sediments. Will either Steripen filter remove enough silt to enable the steripen to do its thing?

Asked by: UtahHo

I've a new Steripen Classic 3-I find when using the pre-filter there are still lots of white pieces of debris/particles in the newly filtered water. The filter is on right but is loose as there are only 2 sides with grips on. Is this normal?

Asked by: Marisa

My Prefilter doesn't screw to the top of my 32 oz 10 year old Nalgene bottle. Their is a great deal of friction between the bottle and the rubberized blue rim of the filter. When I align the threads the friction is just too great to overcome.
