When clear water is not available, use the Water Bottle Pre-Filter by SteriPEN. The Pre-Filter filters out particulates and debris and fits most wide-mouth water bottles.
Once water is filtered, attach the SteriPEN Classic or Journey to purify the water using UV light, ready to drink.

Features:

• Filters larger particles from river or lake water
• 4 micron screen
• Attaches to most wide mouth water bottles
• Pour water in, or submerge bottle to fill through filter
• Full instructions included

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.

Features:

• Fits most water bottles
• Adapts for use with SteriPEN
