The Katadyn Pocket, the top-of-the-line offering in Katadyn's Endurance Series water filters, is designed to provide maximum water capacity and high performance. Filters bacteria and cysts, including Giardia and Cryptosporidium. Lifetime warranty.


Katadyn's Endurance Series water filters are designed to provide maximum water capacity and high performance even under the most rigorous conditions. Built to last, the Katadyn Pocket is the top-of-the-line offering in the Endurance Series. Katadyn believes the Pocket is simply the longest-lasting and most durable microfilter available today and stands behind their claim by offering a lifetime warranty on the Pocket.

A 0.2 micron ceramic filter, the key to the Pocket's extended life and durability, is effective against bacteria and cysts, including Giardia and Cryptosporidium. The Pocket can produce an astounding 13,000 gallons of drinkable water, depending on the quality of the water source, before filter replacement is required! A rugged aluminum exterior protects the filter from breakage and freezing, rendering the Pocket almost indestructible. The filter can be removed and cleaned to combat bacterial growth.

A simple-to-use ergonomic pump allows the Pocket to easily filter up to 1 quart of water per minute.

The Pocket includes an input hose with modular pre-filter, an output hose with a universal bottle clip, a measuring gauge to monitor the life of the filter, and a hydration system connector. A deluxe carry bag has sewn-in field instructions and field tips. The Pocket also comes with a tube of silicon lubricant to keep parts moving smoothly and efficiently. Two abrasive cleaning pads are included for regular cleaning of the Pocket.

Likes: The best of its kind that I have found out there. I have used this in the field and have included it my emergency prep equipment proving to be incredibly sturdy and predictable.

Dislikes: On the heavy side when you are counting ounces on a hike. Also was surprised how expensive this product was compared to the competition.

Likes: This filter is superb. It is solidly constructed and built to filter thousands of gallons. It doesn't feel cheap or flimsy like some other models. The filter is compatible with a small carbon filter accessory that is good for about 50 gallons per refill. The carbon filter, combined with the ceramic, will give you clean water pretty much anywhere. I recommend this not only to backpackers but also to international travelers.

Dislikes: The sleeve is made of plastic. While it is well-constructed, the smooth surface doesn't give you a good grip when it's wet out. I added some grip tape to remedy that.

Like all water filters you have to make sure it is properly used in climates that reach frozen temperatures.

Likes: Really nice filter. Very high quality and works great.

Dislikes: A little on the heavy side but I'd rather carry a little extra weight and know I have a bulletproof, extremely reliable filter.

Likes: Wonderful. I took this on a 50 miler and it was fast and did everything I needed it to do. I also liked how it came with spare parts insteaed of having to order them if something broke.

Dislikes: I wish the outlet hoses where slightly longer.
