Nothing is safer or easier to use for purifying the most demanding backcountry water sources than the Guardian purifier. Originally designed for military squads, it brings this highly advanced technology to global travelers, backcountry users, and those stocking emergency kits. Fast and easy to use, this pump purifier offers the added viral protection you need when traveling in developing nations and popular wilderness areas. The filter cleans itself while pumping. Its advanced hollow fiber filter offers the most reliable way to purify even filthy water conditions. Add its long-lasting performance and revolutionary self-cleaning ease, and this may be the only treatment device you’ll ever need. With user-friendly handling, long life span and compatibility with standard drinking bottles it is a great companion for every trip.

Fast & Easy: Pumps a rapid 2.5 liters per minute, offering added viral protection without the need for chemicals, bulbs, batteries, or waiting.

Self-Cleaning: Pump self-cleans on every stroke, providing consistently fast flow rates with zero hassle—no backflushing or filter-scrubbing ever required.

Long-Lasting: Leading-edge hollow fiber cartridge treats up to 10,000+ liters.
Extremely Durable: Engineered to withstand heavy use, freezing, drops*, and harsh environments.

    Scheint sehr gut. Praktische, kleine Tasche.

    Ich bin mehr als zufrieden mit dem Wasserfilter. Gewicht und Packmaß sind im akzeptablen Bereich für längere Rucksacktouren. Die Filterwirkung ist absolut perfekt (zumindest bei den Wasserquellen die ich bisher genutzt habe- Durchfall hatte niemand aus der Gruppe "grins"). Dir Grundsätze zur Entnahme von Oberflächenwasser sollten natürlich beachtet werden (schnell fließend, Quellennah, nicht gerade in Industriegebieten etc.)

    Die Pumpe ist kleiner und leichter als gedacht, sehr gut im handling. Habe sie im Gelände noch nicht ausprobiert, denke,sie hält, was sie verspricht.
