This is the most amazing water filter on the market. If you are looking for a cheap piece of junk with a plastic handle that might break, buy any of the others on the market. This is used around the world. I have used it in the US and abroad. My friend convinced me since he had used it on a mission trip in the Philippines. I talked to a guy who, while in Utah, could not find anything better than a mud puddle to drink from. He pulled out his Pocket Katadyn and it worked great. Other filters have a relatively short life span. Think about this. The Pocket has possibly a 13,000 gallon life on one filter. If you were to use this filter to pump only one gallon a day, you would need to buy a new filter element 35 years later. That's assuming your not normally drinking from a mud puddle. Even when the filter gets hard to pump and dirty, all you have to do is open it up and clean it out and it will pump smoothly again. If you consider the life span of this pump it may be the cheapest filter on the market. But if you are one of those people that like to buy cheap things that break and have to be replaced buy one of the cheap filters out there.

True this one is a little heavier, but it is worth having a filter that will work and has a metal handle so you won't have to worry about breaking it. Although if you do drop it on a rock it is possible to break the filter element. So caution is still needed.

I added the Carbon charcoal extension that enables you to drink from virtually any source. The extension was only around 10 to $12.

This is the best filter on the market.
Well worth the money.

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.

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.
