Remove larger particles from untreated water on hikes or camping, before sterilizing with a SteriPEN.

Removing particulates before you purify your water with SteriPEN’s UV technology is highly recommended and makes for a much more pleasurable drinking experience.
The SteriPEN FitsAll Filter effectively removes particulates from water with the use of a durable 4 micron screen. Its unique design, featuring the filter cup and funnel fit, offers flexibility to filter water into bottles with a wide range of mouth sizes, including narrow-mouth bottles such as commercial water bottles, soft-drink bottles, canteens and SIGG™ bottles. On wider-mouth bottles, such as Klean Kanteen®, Gatorade® and Nalgene® bottles, only the cup is necessary.??
Water can be poured through the FitsAll Filter or you can submerge the combined FitsAll Filter and bottle of choice. The FitsAll Filter cup also serves as an adapter that allows the SteriPEN Journey or Classic to be used with these wide-mouth water bottles in the inverted position.
