    Comments about Katadyn Pocket Filter with Output Hose:

    Had this filter for about three years. Have used it on thru hike of Ouachita Trail and yo-yo hike on the Ozark Highlands Trail. Both hikes were one month in length.

    If your gear must work, this is the filter to get. Thing weighs more than the one pound advertised but it's built like a tank. Don't think you could break it. Machined metal (milled) top and bottom, thick plastic middle, and thick walled hoses. Really well thought out.

    Can get hard to pump after about 128 oz of relatively clean water and 64 oz of dirty water. This is because of the 0.2 micron ceramic depth filter. Once dirty the filter is easy to clean with included scrub pad. Usually unscrew to drain filter after use anyway, so just clean real quick.

    The filter comes with 2 scrub pads, extra o-ring, lube, go/no-go filter gage, and water container attachments (never used), and a sturdy carrying case.

    I have filtered more than 150 gallons of water through this thing and the filter is no ways tired. Advertisements state the filter is good for up to 13,000 gallons. Don't know about that. Guess it depends on how well you clean it. Hope it last close to the advertised usage because buying a filter for the thing is like buying a whole new filter.

    Anyway, if you are like me and your gear is your legs and must work during your hikes, you can count on this filter to make it with you to the bitter end.

      I'm in the Army and I have used this in Iraq and Afghanistan. Works great, easy to use, easy to take care of. Only drawback is that it doesn't have a carbon filter. water is generally good but won't take out complex minerals and chemicals. you can get an in line carbon filter for about $10.

        Comments about Katadyn Pocket Filter with Output Hose:

        Don’t mess around with cheaper filters having a reliable water filtering source is crucial. Spend the extra money and get the peace of mind of having the best most reliable filter. This thing is built like a tank and will not ever let you down. It filters great and takes out all that nasty stuff that will make you sick. The pre filter on the intake tube is nice too, keeps big particles from entering the filter. It pumps remarkably fast compared to other filters. Some other campers were using MSR filters that would yield just a few drops every stroke. This Katadyn filter really pumps it out. Filling Camel backs is easy just take off the mouthpiece on your camel back drinking tube and stick the outlet hose of the filter into it and start pumping. Filling an entire camel back really doesn’t take long at all. Cleaning it is really easy and the filter element life of this thing is incredible. The only downside I can think of is the filters weight. It is heavier than other filters but don’t pass it up because of that. It is definitely worth carrying the extra little weight. The Katadyn pocket filter is worth every penny, you’ll definitely enjoy owning one. Other campers will enjoy it too when their filters break down and they need to borrow yours. I have had to lend mine out to thirsty campers with other broken filters many times. The carrying bag that it comes with is nice and sturdy. It also comes with some cleaning pads, lubrication, and an extra o ring for the plunger. The warranty is amazing as well.

            Comments about Katadyn Pocket Filter with Output Hose:

            havent puchased this yet but as i sit at home with mild diarrea, and an unpaid day off, researching water filtration and purification this is the only filter WORTH purchasing. (1)Filter Life;pocket filter life is up to 13000 gallons. thats 5 gallons a day for a little over 7 YEARS. Most other filters average around 150 gallons or 5 gallons a day for 30 days. to equal the pockets life one would have to purchase 87 replacement filters. WOW THATS ALMOST 3500 BUCKS.(2)Filter Size;most filters have a 0.3 micron sized filter which can successfully remove bacteria and protezoa suchas giardia. however to remove cryptosporidium a 0.2 micron filter is required, which the pocket filter has. Additionally iodine does not kill crypto nor does sodium hypoclorite(bleach)and prolonged use can cause kindney and liver problems. clorine dioxide does kill everything if you can stomach it. giardia and crypto infections can last weeks meaning time off work $$$$$$$. Pocket filter is garanteed for 20 years making it the stongest longest lasting most reliable and in the long run most economical filter on the market. FYI Crypto has been found in 77% of surface water in the U.S.. Viruses have been found i 20% of surface waters(per epa website)to kill them one would have to resort back to chemical treatments which taste like [*] or simply boil. boiling is considered the most effective form of water purifacation however it takes a long time and youre left with hot water to drink(to cool put container/ resevoir with purified water back in stream taking care not to contaminate mouthpiece/opening)(chance of viral infection is very low compared to bacterial and protezoen, I'll risk it)now for soluble toxins such as pesticides/herbicides and heavy metals such as mercury(which is abundant in surface waters following forest fires) use the katadyn activated carbon in line filter($15).Boil ,Pocket filter and carbon filter and you will have better quality water than most bottled water(fyi bottled water has the same FDA regulations as municiple tap water and most of it isn't any better than tap water)

              Comments about Katadyn Pocket Filter with Output Hose:

              I bought this filter 20 years ago and used it extensively. Due to a variety of factors, I stopped backpacking for about a decade and have resumed backpacking. Last summer pulled out the filter, cleaned it out, which is easy and it worked just like new. I understand the newer model has a clip to place the output tube in a water bottle, but I have jerry-rigged my own clip and it works great. If the filter gets dirty, it can be a little difficult to pump. However, a quick and easy cleaning of the ceramic filter remedies the problem. I love this filter and am really happy that I didn't discard it or give it away in my hiatus from backpacking.

                Comments about Katadyn Pocket Filter with Output Hose:

                The Katadyn filter is an excellent product, the best of it’s type in my opinion. It also not the right filter for everyone. The Pocket is signifigantly heavier and more expensive than many other water filters on the market, but the additional weight is a function of how the filter is designed itself. The Katadyn Pocket is very solidly built—only exceptional abuse will damage the thing. Also, the thick ceramic filter adds to it’s weight, and is actually the reason I chose it. Unlike many other similar filters, the Pocket does not become exceptionally nasty if it’s not dried. Also, the filter cartridge lasts for many, many times longer than any other model on the market. In all, I don’t mind the bit of extra weight when I’m backpacking in the wilderness, and I love the durability and ease of cleaning, especially when I travel in developing countries

                  Very well built. It weighs more than some of the others, but It will definately outlast them. If the ceramic element gets dirty it can be hard to pump, but it is so easy to clean that it isn't a problem. The ceramic element has a very long life so it is always ready to go. If you use a filter often this is a must have.

                  Very sturdy and built to last. I've had it for 4 years now and have had no problems with it. Dont expect it to filter out color of water when the water contains significant amount of mineral (ie. iron). As mentioned by reviewer below, it is not for everyone. The water output is small compared to other models out there. My right arm got significantly bigger after pumping 2 liters of water. No need for lifting weights!

                    I can't speak for the current model, but I bought the original in 1982, it's been to Africa twice, UK, Russia, all over the USA & Canada and has never failed. In the last few years some of the seals have started to leak so it water squirts out the joints a bit when pumping, but seriously, it's 25 years old. Hmm, maybe time for a new one...

                      Comments about Katadyn Pocket Filter with Output Hose:

                      I've tried (and broken) numerous different water filters. I consider myself very gentle with my equipment but lately several of my new and old "plastic" filters have failed and broken after only a few uses. I won't "name names" but these were name brand filters... I finally abandoned my quest for the uber-light and got a Pocket Filter. I could not be happier with my decision. The Pocket worked great, every time. My husband and I just finished a month-long hike in the high Sierra's and never worried once about whether our water filter was going to work or not. While on the trail, we spoke with several other hikers who broke their "plastic" filters too and were resorting to purification pills as a back-up. We told them to get a Pocket. The Pocket was easy to use, easier to maintain and solid as a rock. Do not let the weight of this filter dissuade you - you will be glad to have this filter when it really counts. The only thing I wish I could change would be to have a longer output hose. A MINOR suggestion and something I can remedy myself.
