Katadyn Pocket Microfilter

When you're trekking through remote wilderness, camping at high altitude, or traveling to regions where water safety is uncertain, having a reliable water purification method can be the difference between a successful expedition and a medical emergency. This compact microfilter represents one of the most trusted solutions in the outdoor industry, engineered by a Swiss manufacturer with over 80 years of water filtration expertise. Designed for serious adventurers, backcountry hikers, and international travelers, this ultralight system fits easily into a pack side pocket while delivering exceptional purification performance that meets or exceeds EPA standards for pathogen removal.

• Hollow fiber microfiltration removes 99.99% of bacteria, protozoa, and cysts without requiring chemical treatments
• Ceramic cartridge rated for approximately 25,000 liters (6,600 gallons) of continuous use before replacement needed
• Weighs only 2 ounces, making it ideal for ultralight backpacking and minimalist travel kits
• Compact 7-inch length with integrated squeeze mechanism—no separate pump or container required
• Field-cleanable design allows users to extend cartridge life through simple brush cleaning in the field
• Produces 0.5 liters per minute flow rate, suitable for individual hydration needs on extended trips
• Compatible with virtually any standard water source: lakes, streams, rivers, and questionable tap water internationally
• Swiss-engineered construction with durable plastic housing and stainless steel components resistant to corrosion
• No batteries, no maintenance beyond periodic cartridge cleaning, no replacement of expensive filters in remote locations

In real-world backcountry conditions, this microfilter excels when reliability matters most. Whether you're drawing water from a high alpine lake, a murky stream in Southeast Asia, or an unreliable rural water system, the hollow fiber technology creates an impenetrable barrier against Giardia, Cryptosporidium, bacteria, and sediment. The intuitive squeeze design requires no learning curve—fill the intake tube, submerge in any water source, and squeeze directly into your water bottle or hydration bladder. The modest flow rate actually works in your favor on long-distance treks, as it encourages measured water consumption. Field testing by outdoor professionals confirms the cartridge maintains consistent performance throughout its rated lifespan, and the brush-cleanable design means you're not stranded without purification if you run out of replacement cartridges during an extended expedition.

This microfilter is purpose-built for wilderness athletes, international backpackers, and preparedness-minded travelers who refuse to compromise on water safety. It's the choice of expedition leaders, remote research teams, and anyone who takes their hydration security seriously. For trips where weight matters, reliability is non-negotiable, and the water source is unknown, this proven system delivers uncompromising performance in an ultralight package.
