Remove debris and particulates from water with the Water Bottle Pre-Filter from SteriPEN. The 40 micron durable nylon screen removes debris and particulates from your water, preparing it for treatment with a UV purifier. Designed for 32 ounce Nalgene bottles, this pre-filter will work with most bottles with a wide mouth. When used with the SteriPEN Classic 3, Ultra or Aqua, it forms a watertight seal. Features:
* Reversible cartridge for compact, convenient storage
* Dual water seals to prevent contamination of drinking surface
* Used with Nalgene and similar 32 ounce wide-mouth water bottles
* Manufacturer: SteriPEN
* Use With: Wide Mouth Bottles
The SteriPen Pre-Filter is designed to filter out particulates and sediment from your water before you apply the UV purifier. Designed for use with wide-mouth water bottles, the Pre-Filter has a 4x4-micron filter screen that sifts sediment and small particulate matter out of the water. The screen is held within a cartridge with an air vent at the top and allows for either pour through or immersion methods to filter the water. Once the water is cleared, the water purification process employed by the SteriPen UV water purifier will be more effective.
About SteriPen Ultraviolet (UV) Water Treatment:
The ultraviolet (UV) water treatment method has now been used for over one hundred years, and is currently used to purify drinking water by some of the largest cities in North America, Europe, and Asia, including Seattle, Washington and Tempe, Arizona. Ultra violet light is also used by bottled water manufacturers to purify their source water.
The EPA officially recognized the use of UV water treatment as a proven, viable technology in 1996. In a simple but effective process, UV purification destroys over 99.9 percent of harmful microorganisms in drinking water. The UV energy emitted by the light is absorbed by the cells within potentially harmful microbes. The UV energy breaks down the cells' ability to reproduce DNA--making it impossible for them to reproduce and make you sick.
Thousands of outdoor enthusiasts all over the world have trusted SteriPen for many years. Introduced to hikers and campers at REI in 1999, Time Magazine named the SteriPen one of the "Best Inventions of the Year" in 2001. SteriPen's speed, effectiveness, and portability have impressed end users and media alike. Backpacker Magazine, Newsweek, and the Today Show have featured SteriPen as a powerful, user-friendly alternative to pumps, chemicals, and filters.
SteriPen products have been tested by the Water Quality Association (WQA) against the US EPA Microbiological Water Purifier Standard. SteriPen has received the WQA's Gold Seal, certifying that SteriPen purifies water safely and effectively.

After a while the filter can start clogging with sand and other debris, but i've been able to back wash it to get most of it out. Don't get me wrong, I love my gravity filters, but if you need 1.5 liters of water in 2 minutes, this is the product to buy!
If the water you intend to sterilise is cloudy, if possible collect the water in a container and allow the sediment to settle. Then pour the clearer water through the prefilter making sure the air valve is open.
If you bottle fill from a stream, pre wet the filter and reinstall it, then open the valve and submerge the bottle up to the air valve...I leave half the valve under water and half above to get things started, then you can position it to get the maximum flow by observing the bubbles.
It’s not fast, but it’s doable.
Naturally, if you were pumping the water in through a Katadyn or MSR it will be much faster, and I usually have my Katadyn Pocket at hand.
But if you don’t want to pack your high spec filter, this prefilter gives you a workable option, albeit slower.
We had planned to camp alongside of a clear running mountain stream and had no idea that we would actually need the filter. But, we had an unexpected rain storm that lasted for two days and the clean, clear, mountain creek turned into muddy wash.
The SterinPen Pre-Filter was our only means of cleaning the silt and trash out of our water prior to using our SteriPen Traveler UV light clear water Purifier.
The pre filter is slow and the UV light filter eats batteries like a hungry animal. It took two of us about two hours and two sets of batteries to filter and clean 10 gallons of water. Not fast or cheap but it beat the heack out of the alternative.
In the past I've used a couple of pump type water filters but they took up a lot of room, were just as slow and I never felt as comfortable drinking the water that they filtered as I did using the SteriPen combination.

The only word of caution that I would have relates to the moderate fragility of the replaceable filter cartridge: carry it protected in your pack because, otherwise, any sharp object could likely puncture the filter fabric. It is for that very reason that Steripen recommends to insert the filter cartridge upside down in the prefilter body when you are storing it after use.
The filter cartridge is washable and should provide average hikers good service for a very very long time. If confronted with really dirty water with a lot of sediments, as I have encounterd in some tributaries of the Amazon River, you may want to use the prefilter AFTER having collected that water in another vessel to let it settle for awhile. Then you would be in really good shape preventing near immediate clogging of the prefilter.
Have a drink on me!😉
Er filtert keine Bakterien, Viren oder chemische Verschmutzung. Bei sichtbar verschmutzten oder bakteriell bedenklichen Wasser habe ich deswegen einen richtigen Filter von Katadyn (Hiker).
