The FitsAll Filter from SteriPEN allows you to prefilter your water before purifying with your SteriPEN. This clever device acts as a 4-micron filter and a funnel/adapter that works with nearly any bottle type. In addition, the FitsAll filter allows the SteriPEN Classic and the SteriPEN Journey to be used in the inverted position with wide-mouth bottles for easier operation.
The FitsAll Filter’s unique design offers the flexibility to filter water into bottles with a wide range of mouth sizes. Water can be poured through the FitsAll Filter or you can submerge the combined FitsAll Filter and bottle of choice. The SteriPEN FitsAll Filter cup and funnel fit into 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.
Weighing only 2.3 oz., the FitsAll Filter is made with rugged, flexible materials that allow the filter to be squeezed during storage and return to shape when unpacked.
