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.

5.0 out of 5 stars Easy to use pre-filter for steripen
By Nathan on June 20, 2019
Perfectly fits a standard wide mouth nalgene water bottle and works well to filter out sediment from water before treatment. Rubber gasket ensure no contaminated water reaches the inside of threads on your bottle. But do not forget that your nalgene cap isn't protected so don't accidentally submerge that unless you're ready to clean or sanitize the cap. If air vent is removed and flipped upside down into storage/transport position, a standard cap has enough reach to screw on top and keep the whole unit as one with less chance of losing during storage or transport. This is my go to setup with a steripen for camping or kayaking so I do not have to pack a lot of extra water. With everything attached, nalgene and pre-filter will fit into most water bottle pouches. I recommend this product!
