If you like your water to taste like iodine, this purifier is for you. If my life actually depended on it, obviously I would drink water from this bottle. Otherwise forget it.

Although this was easy to assemble, the spout on the bottle does not disperse water very well. The hole is too small and a great deal of water spurts out the sides (which is not going through the filter so it is impure water getting into the cup). Also, the little holes on the lid are confusing as to their purpose. I used this on an overseas trip and will probably never use again as it did not effectively purify the water and was quite frustrating to use.

A wonderful devise for backpacking or a long day of river fishing. Light easy to use and as long as there ie water around your in good shape. Great for back country camping.

I have used my Katadyn Exstream extensively while living and traveling internationally. It’s as convenient as a regular water bottle, and you can just fill it from the tap wherever you are. I also liked not using all the plastic bottles that people waste, especially in areas, like most of Central America, where most of them end up littering the streams, countryside, and side of the road. The filters also last a very long time when you are using them with relatively clean water to begin with. As for camping, they can get clogged quickly with dirtier water.
Note that the filters are by far the most expensive part, and look at how much you can expect to use them before buying this product.

This bottle filters everything. The flow isn’t the best and it tastes a LITTLE weird, but it filters everything including leptospirosis (important on our trip to Kauai). Katadyn is the way to go.
