The Pocket hails from Katadyn's Endurance series, a high-quality line of filters that produce up to 100 times more water than standard water filters. The Pocket is so tough, in fact, that it's the first choice for extreme adventurers like Mike Horn. Plus, it's the only water filter with a 20-year warranty. Other features include a measuring gauge that indicates when you should change the filtering element, a cushioned base that makes it easy to pump on all surfaces, a prefilter, and a carrying bag.
Why Water Filtration Is Important
The World Health Organization (WHO) attributes 80 percent of all travel diseases to contaminated drinking water. Drinking water contains three groups of pathogenic microorganisms: viruses, such as hepatitis A, Norwalk virus, or poliovirus; bacteria, like e-coli, salmonella, and cholera; and protozoans, such as giardia and cryptosporidium. Tap water and ice cubes are usually the culprits when traveling, but even bottled water can be questionable. The backcountry is also a source of waterborne illness. A pristine stream may be safe one day and contaminated the next, as microorganisms stemming from human and animal waste are typically spread by rain and runoff. As a result, the U.S. Center for Disease Control and Prevention recommends treating water from every source in the backcountry.

The Switzerland-based Katadyn has been producing high-quality portable water systems since 1928. Katadyn products are used by militaries, health organizations, and outdoor adventurers worldwide, making it the global leader in portable water treatment. With subsidiaries in the U.S., Germany, France, and Singapore, Katadyn products are used wherever safe drinking water isn't available, whether for travel, camping, or humanitarian applications.
The most rugged, longest lasting microfilter available. Chosen by the U.S. military and expeditions due to it's extreme durability and dependability. For those who want the best.
The Katadyn pocket has a well-deserved reputation for reliability and durability. It is one of the pricier filters but is also rated to pump much more water than its competitors. The Katadyn pocket isn't light (20 oz), but the better competitor pumps are also about 16 oz., so this isn't too much heavier. Some of the others pump a little faster, but they are usually 0.3 micron filters, whereas this is a superior 0.2 micron filter. The Katydin pocket is also the only pump with a lifetime warranty (excluding wear of the ceramic filter). If you search the web, you'll find a lot of reports of the $75 pumps eventually breaking, especially plastic handles. If you have to replace them (or their short-lived filters), you've already well into what it would cost to buy a Katadyn Pocket. This thing is pretty damn tough, and the only way to break it would be to take it apart and drop the inner ceramic filter. I've found it easy to use, though you need to hold it upright to keep water flowing. During 8 years of trips through the Sierra Nevada, Utah, New Hampshire, and Wyoming this filter has never disappointed. General tips to extend the lifetime of any water filter: 1) Use running water from streams/rivers whenever possible 2) Position the floater so that water inflow comes from the top of the stream and not the bottom (where a lot of sediment stirs about) 3) Rubber band a coffee filter around the prefilter to keep particulate matter out. 4) After pumping, unscrew the filter and drain the excess water. This filter is silver-impregnated though, to prevent microbial growth. If you want to keep your packing weight down, carry your water in collapsible water bladders instead of thick plastic bottles. You can buy a cheap adapter so that water is pumped from the filter right into the water bladder. If you search around the web you can find the Katydin Pocket for around 180 or less. I tend to pack light and have lots of fancy lightweight gear, but I am serious about my water sources and don't plan to compromise on this beauty.
