When clear water is not available, use the Water Bottle Pre-Filter by SteriPEN to filter out particulates. This unit screws onto the top of wide-mouth drinking bottles, and has a removable mesh filter cartridge with a 4 micron screen in the middle of a collection area on top, to hold back the sediment and leafy or other debris as you fill it gradually. Replacement screens are also available for it, here.

Product Notes:

The top unit fits on any Nalgene® brand wide-mouth water bottle (like the one shown on the right of the product photo for a related product, the SteriPEN - FitsAll Filter) and on similar 2-1/2 inch diameter wide-mouth water bottles.

Of course, it also works on SteriPEN's own Classic, Journey, Adventurer or Traveler bottles, although you do not need to use those proprietary ones. But if you are, the Pre-Filter assembly can do double duty there, if you are using it in conjunction with one of their their Handheld UV Water Purifiers: if you remove the filter cartridge (which is easily done with just a twist), it can hold the UV sterilizer in place, instead of you having to hold that in and stir it by hand.

The main unit has a dual O-ring seal protection to prevent the sediment from getting into the bottle. Dimensions: 67mm (2.6 inch) outer diameter at the bottom, 47mm (1.85") high.

The Replacement Filter Cartridge is of course designed for that same Water Bottle Pre-Filter. These cartridges encasing a 4-micron mesh screen are re-usable between uses after rinsing them with clean water, but they may eventually become clogged or frayed. To install them, simply insert the Replacement Filter Cartridge into the opening in the base, oriented with the air nozzle tip facing up, line up the tabs and position it beneath the tabs on the base, and turn it slightly to lock it into place.

Suggested Usage:

Simply screw the base onto the top of your target bottle in lieu of its regular lid (ensuring the prefilter is positioned with its tip facing up), open the tip of the air vent, and gradually pour water into the base (there is a collection ring about an inch deep).
