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.
In 1980, this thing was $180 at REI. After a bad experience with the Lifesaver LS6000 last year, I finally pulled the trigger for the Katadyn Pocket. This review compares my experience using the Katadyn Pocket Micro/external carbon cartridge/Steripen Classic as a system vs the Lifesaver LS6000/4000 water purifier. I won't spend much time on the external carbon cartridge and Steripen here because they will be reviewed separately with links to them at the end of this review. Use this review to supplement what others are saying.
I originally chose the Lifesaver LS6000 (also now available through Amazon) over the Katadyn for a remote Arizona camping trip because it was a PURIFIER rather than just a filter. The LS6000 (LS4000 is the same technology, just smaller capacity) seemed like it would be more convenient because in actual operation, it is essentially a single, self contained collector/water bottle with an integrated activated carbon filter. But after a frustrating 1 week experience with the LS6000 putting GALLONS of water through trying to get rid of a cheap plastic taste, I finally returned it to the distributor.
I paid return shipping for the privilege of testing the LS6000 and I still wasn't going to have a filter for my trip. Not too happy about that. While it was probably filtering to the 15NM spec, more than 13 times the filtering power of the Katadyn (200NM), it just didn't hold up to the video claims that the water produced tasted like bottled water. That was my only real beef with the LS6000. See my review under the LS6000.
The backup plan was to order the Swiss made Katadyn Pocket Microfilter, along with the Katadyn activated carbon filter cartridge and the Steripen Classic...all at fantastic sale prices + free super saver shipping at Amazon. The Pocket retails for $289 and I paid $189 with free super saver shipping. Source the Eneloop batteries for the Steripen from whom you choose, but they are the only batteries I recommend for the Steripen. It took 8 months to get everything together but the batteries taking advantage of Amazon's best discounts.
With the 2 hoses (intake/output) plus the charcoal filter cartridge and Steripen, this system becomes a bit more of a project to filter and purify water than the Lifesaver. But, I have to say that that in terms of water that was just pure joy to drink, this busier (and initially pricier) setup was superior to the simpler Lifesaver system. I was also into this combination for about $313 for everything ready for the wilderness vs $179 for the LS6000 on Amazon.
Another downside of the Katadyn is that after you are done with it, it's a little busier to put away. It's a good idea to remove the hoses, carbon cartridge taking care to put the output hose (along with the carbon cartridge) in a separate ziplock bag to prevent cross contamination. The covers for the hose connection ports should be installed, also to prevent cross contamination. It all fits in the Katadyn's pouch. If you used the Steripen, too, then you should dry it off, recap it and return it to its ventilated neoprene pouch. With the Lifesaver, you just close the teat, snap the cap back over the teat and put the bottle back in your pack.
Using the Katadyn with the Steripen- Much of what I've read points to treating for viruses in pristine free running North American waters possibly being overkill. In clear running mountain streams I probably wouldn't bother with the Steripen as the Pocket alone probably will take care of the "bugs" that would be found under those conditions and the carbon cartridge will do its job to provide the fresh clean taste you might expect. However, the closer you get to high use areas by people and animals, the more I would look at some way of dealing with the potential for viruses, e.g., Steripen. Treating with the Steripen takes about 90 seconds for 1 liter of water and 48 seconds for 16 oz. The LS6000 removes viruses during the filtering process without the need for any further treatments. I would be cautious drawing water from sources where boats with fossil fuel motors operate no matter which filter system is used..
I tested the output of the Katadyn without its optional carbon filter under the same conditions as the LS6000 and found the water also had an off taste, most likely imparted by the ceramic filter. The taste wasn't the same or as offensive as the LS6000 with its integrated activated carbon filter, but you could still pick up that the Katadyn's output was "off". I put the Katadyn activated carbon filter on the end of the output hose, pumped a new cup of water and VOILA(!), the water was PERFECT!
IMPORTANT UPDATE 5/12/2010
Re: Off taste in Katadyn Pocket Microfilter-- After reading reports of others obtaining the fresh clean water taste WITHOUT an activated carbon filter, I pursued this a little further. After drying the filter for a few days, I reassembled everything and tried again, except this time NO CARBON FILTER. After pumping 12 oz of water through the dry filter into a measuring cup, there was NO OFF TASTE AT ALL. Referring to the user guide it says to flush .5L (~1 pt) of water through the filter before 1st use, .2L (~7 oz) before each use thereafter and 1L (~1 qt) after having air dried the filter for long term storage. As reported in this update, I had pumped only 12oz of water through the dry filter. It would seem that if an off taste is occurring, it can managed by flushing the filter before filling the container. Will look at this further and update this review again. However, the carbon filter might still be needed to remove mossy or fishy tastes from streams, etc. The original review continues below.
So far I have tested the Katadyn with our hauled tap water, from our rain barrel system (not available for the LS6000 test) and then on to the (brown) spring streams of the Kaibab National Forest, natural standing water "tanks" in the Sycamore Canyon Wilderness and the nicely flowing waters of the Upper Verde River. While the rain barrel water tasted like the tar from our asphalt shingle roof, water filtered from the other sources with the Katadyn/carbon cartridge was a pleasure to drink (used the Steripen in ALL of these waters!). The LS6000 had no follow-on testing because I couldn't produce satisfactory results from our hauled water source.
The output hose for the Katadyn has a spring loaded clip that attaches nicely to my canteen, cup, or most any other container. When using the Pocket with the activated carbon filter, an extra length of tubing is recommended from the output of the carbon filter if it does not fit stably onto your water container. Empty containers with narrow bases can be a little squirrelly to fill. With the Lifesaver, you just unscrew the bottom, submerge, replace the bottom, pump a few times, and open the teat and drink. Putting it back in your pack is a snap. You can also use the LS6000 to fill containers by opening the teat and aiming the pressurized stream accordingly. My Katadyn was supplied with an "O" ringed hose adapter for filling camelpacks.
Using the Katadyn, even without the optional carbon cartridge, is a bit of work for only a 12 oz drinking cup of water. Once you pull this device out of its pouch, connect the hoses and set up the water container, it is best to fill at least 1 32 oz Nalgene bottle, canteen, etc. plus the containers of others in the group. In the wilderness, I would probably want to remove the Katadyn's ceramic cartridge and air dry it every 3-4 days. I also like to blow out the carbon cartridge and dry it as much as possible. I have not had to clean the ceramic cartridge, even after the tar tasting water of the rain barrel. The LS6000 cartridge is a little busier to remove and dry. The integrated activated carbon filter of the LS6000 should probably be left alone unless you are going to replace it. Probably wouldn't bother drying the LS6000 until returning home.
The Lifesaver, because of its teat system, is more of a personal water bottle (kind of like your toothbrush is personal). The teat is designed to be pulled open with your teeth. The LS6000 will become more work in water sources where you are unable to submerge the entire bottle to collect water. Worst case, you have to resort to a smaller scoop, dig or use the supplied sponge to soak up water and squeeze it into the bottle. The LS6000's cartridge can be backwashed, but looks to be a chore. With the Katadyn, I was still able to pump from sources that were only 1 inch deep. As long as you can submerge it, the Lifesaver system gets you collecting water and drinking in seconds while you could still be connecting hoses on the Katadyn. The Lifesaver will be more work to fill containers.
Another minor concern I have with the Lifesaver is that if you neglect to secure the cap for the teat or if its seal deteriorates, you could contaminate it when you submerge it in a water source. With the Pocket, the intake and output hoses are separated substantially, minimizing the potential for cross-contamination. The Katadyn also comes with port caps that should be installed prior to putting it away. Remove the output hose and cap the output port first, then the intake.
As far as maintenance goes, the Lifesaver seemed a little busier to maintain than than the Katadyn. There's really not much to do with the Katadyn if you draw water from clean sources. Clean the ceramic cartridge if it gets harder to pump and use the supplied gauge to measure the diameter of the ceramic if you are cleaning it a lot. Lube the 'O' ring on the pump with the supplied silicone, when necessary. You can download the servicing instructions for both prior to purchase. I certainly recommend that in the course of your decision... Read more›
Product Description
Amazon.com Product Description
Water treatment products are in high demand for outdoor enthusiasts, international travelers, and relief agencies. Few are better for long-lasting continuous use, however, than the Katadyn Pocket water microfilter. Made of heavy-duty materials, the Pocket features a silver-impregnated ceramic element that's effective against bacteria and protozoa even in extreme conditions. Unlike disposable filters, the ceramic element can be cleaned several times, even in the field. More importantly, the element filters all microorganisms larger than 0.2 microns (0.0002mm), producing clear, drinkable water no matter where in the world you are. The pump also includes an improved, round pump handle for better ergonomics and an outlet hose that attaches to water containers with a single clip.
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 ImportantThe 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.
