SteriPEN FitsAll Hydration

The SteriPEN FitsAll Filter effectively removes particulates from water with the use of a durable 40×40 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.
