SteriPEN JourneyLCD handheld water purifier

SteriPEN® JourneyLCD Handheld Water Purifier (JY-RP). The revolutionary SteriPEN JourneyLCD uses universal symbols to take the guesswork out of the water purification process. Journey’s integrated LCD screen displays the user’s dose selection (1/2 liter or 1 liter), battery status and countdown timer. The LCD screen also tracks the number of uses and signals when lamp usage approaches its life limit. At 8,000 cycles, lamp life for SteriPEN JourneyLCD reaches a new high (purify 1 liter 4 times a day for nearly 7 years!). Like all SteriPENs, the Journey is Fast (48 seconds for 0.5 L (16 oz.)), Light (128g /4.5 oz.), Effective, and even easier with it’s innovative LCD screen. The Journey mates with the SteriPEN pre-filter and is sized between our Adventurer and Classic. Journey ships with two non-rechargeable (disposable) CR123 batteries.

  • Dimensions: 18.6 cm (7.3 in.) in length, 4.1 cm (1.6 in.) in width, and 3.3 cm (1.3 in.) in depth.

FtsAll Filter - in commercial water bottle and nalgene bottle

SteriPEN® FitsAll Filter (FAF-ADP) - NEW ACCESSORY! Use the new SteriPEN FitsAll Filter to remove particulates from water with the use of a durable 4 micron screen. It is recommended that particulates be removed prior to treating water with a SteriPEN UV purifier.

The FitsAll Filter’s unique design offers 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.

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. Weighing only 65 g (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. Nested storage dimensions are 88mm (3.5 in.) x 95mm (3.7 in.) x 72mm (2.8 in.).
Available late April 2009
