Katadyn Pocket Water Microfilter

I pumped water out of a canyon reservoir that didn't look so hot. My brother who was camping with me thought I was nuts. I had no problems, water tasted great, and it saved me from having to carry in all the water I would need for a three day hike. Invaluable.

I bought this filter last year and used it camping in the Porcupine Mountains in Michigan. I filtered water from the lake and it worked great. Although i would disagree that it pumps 1L a minute, it does do a sufficient job. The lake i was pumping from had a high iron content and i could definitely tell. I would recommend buying the Katadyn inline carbon filter to remove unwanted tastes.

Put simply - a brilliant piece of invaluable equipment - would not go outback without it.

Pros: reliable, great tasting water, very solid. Cons: heavy, expensive, water gets stuck in the filter after use and is very difficult to get it out Other notes: Does not pump at 1L/min, maybe 0.4-0.6L/min. I used it for a 7 person group for an 8 day hike, so it's definitely heavy duty. I give it 4/5 only because of the trapped water issue, otherwise it's an amazing filter.

Been using the filter almost 6 months now whilst traveling through Central and South America and it's performed faultlessly. We even used it whilst trekking the Inca Trail to Machu Picchu and in muddy streams. It's saved us having to buy lots of bottles of water. Excellent product.

Very well-made water filter, easy to use (pumping). If you are going to buy a water filter for the first time, take the time and look at this one. If I would buy again? Yes 100%

The sturdiest filter out there and it really doesn't weigh that much more than the better filters that cost $70-80. It is rated to 13,000 gallons- much, much more than its competition. By the time you've replaced a filter once or twice on the competition you could have bought this beauty. Search around the internet, you'll find lots of stories about the problems of other filters, even the plastic breaking. Tips to prolong the life of these things: 1) Use a rubber band to secure a coffee filter around the intake filter (to remove large sediment); 2) Use running water from streams/rivers when possible; 3) Using the floatation device, withdraw water from near the top rather than the river/lakebed, where a lot of sediment is stirred up.

The best $200 I ever invested! Really, we put this baby to the test in some nasty looking water on our 4-day backpacking trip and it performed wonderfully. I'm only giving one word of warning here; you will notice a slight filtered taste to the water, but nothing that is not worth drinking. Never got sick off the water, thanks to this little baby. It's fairly lightweight too which is a real plus. Buy this one if you don't want to worry about what you're drinking on your next trip.

All of my friends have different models than me such as: the MSR mini works, hiker, water works, and the katadyn mini. Everytime we go out they MAKE me bring mine. It is the most bombproof filter I have ever seen all aluminum construction, new and improved handle, and insane filter life!!! I would have to say the output on this filter is the best I have seen I can fill up a three liter hydromina bag in about 10 min. I would recommend this filter to anyone.

The pocket filter is great, but heavy. I have used at least six other filters and broke them all. This one can not be beat for capacity and durability. The weight is worth good water and this particular filter could easily be the only one taken with a small to large group. I wont carry anything else except maybe micro pur tabs when the water quality is known to be good already.

It seems the 2003 model of the pocket filter no longer comes with a brush, but is supplied with two green scratch pads. It also comes with a tube of silicon grease and a spare small "O" ring. The bottom of the filter is now flat so that it can be firmly placed on the ground or other surface without trying to balance it on a narrow bottom plate. Another improvement is in the output nozzle. It screws into the top plate and will allow a tube to be run to the container. A metel clip is provided to secure the end of the tube to the lip of a container so it will not "flop around" during pumping. Lastly, the handle has been re-engineered into a mushroom shape which allows much more comfort while pumping. No more "T" handle! At 13,000 gallons capacity per filter, the average owner will never see the day when it must be replaced, unless it is broken. The unit is built to last a lifetime, and comes with a lifetime warrenty, but weighs in at 20 oz. As an active duty U.S. Marine, this is the model of choice for uncompromising performance, durability, and maintainability in a field environment.

The Katadyn Pocket filter is very solid and I'm confident it will give me years of good use (probably a lifetime). After about 50 liters it became quite hard to pump, even though the water seemed pretty low in sediment. This was a noticeably sooner than other filters I've used (especially the far-cheaper PUR Hiker). Also, the filter does not appear to have all the parts described in the directions (notably the cleaning brush --- only brillo-type pads were included). I fear that the absence of the brush may have led me to clean slightly more aggressively than is optimal, scratching the ceramic element in a few places.

This is simply the best filter out there, in terms of durability, capacity, and effectiveness. It is also extremely heavy and not at all compact, but I would choose it any day over the smaller and less durable Katadyns or any other brand. As an added measure against chemical impurities (which are not filtered by the ceramic element), I use the StopTop from my old Pur Scout on the output hose. The StopTop uses activated carbon/charcoal in a manner similar to Brita or Pur pitcher filters to statically absorb certain chemicals (additionally, the StopTop perfectly fits wide-mouth Nalgene bottles). Apparently, Pur stopped shipping the StopTops with their filters because the charcoal also interfered with the purifying iodine, making the main filter less effective. I don't know if the Katadyn would have the same problem, since the filter is silver-impregnated ceramic, but it sure is convenient. Take note that the instructions are a little misleading about cleaning, since apparently the handled cleaning brush is no longer included. Instead they provide large scrubby pads to clean the filter. Highly recommended.
