Katadyn Exstream Purifier Bottle – In Your Choice of Colors
I really wanted to like this product but I found the plastic to be very hard. I also thought it would have more water space. I returned this product.

Took it on a week-long wilderness solo trip. Performed as advertised. Water tasted great, without any chemical taste. The pump is sufficiently productive. Rugged and solidly engineered, but lightweight. Survived considerable abuse. Looks even more rugged now with the print almost rubbed off. Easy to (dis)assemble and clean. Gives you the minimalist feel without leaving anything to desire. Together with an s-binder attached to the loop, has become a permanent accessory in my equipment.

I travel to India a lot. All those stories about the lack of potable water are true. In fact, that scene in “Slumdog Millionaire” (if you haven’t seen it yet, go tonight) where the protagonist is working in a fast-food restaurant and fills an empty water bottle with tap water, and then glues the serrated plastic top – it’s all true. The only time I ever got sick there was when I drank an expensive bottle of designer water, obviously faux.
Still, I love India. It’s all the better now because I take this purification system with me. It’s very easy to use and works well (or at least, I never get sick anymore). Sure, it takes up some room in the carry-on suitcase, but it’s worth it. I now take my Katadyn whenever I travel to developing countries.

Honestly, I only used this for one trip through Peru because I gave it as a tip to our tour guide, who was manic about recycling our wasteful plastic water bottles and who clearly taken by it. She loved it because it’s so simple. Personally I suck down water like mad, and I didn’t find that it held enough water for the day. So, I had to buy some bottled water anyway. If you’re thinking about this product for city-based travels (where tap water can be found) then it’s probably perfect. I did find a solution that works for me, which is a high end but impossible to break water purifier (MSR MIOX) to use with my camel back. Now I never run out of water. The MIOX is expensive and somewhat complicated to use, but I’m an engineer, so it’s fine for me.

I took this water bottle to India, and I drank the tap water and didn’t get sick. This was my favorite travel companion on this trip. If you are going to travel to a country without potable tap water, I would strongly recommend this product. It’s simply not feasible to get bottled water all of the time, and if you’re exposed to excited germs it’s best not to be dehydrated too.
I didn’t test this on muddy icky water, and I didn’t try anything as daring as drinking water from the Ganges. It won’t protect you from impurities like heavy metals, although the charcoal filter should dramatically reduce many organic impurities. I had no problems with customs or airport security, although they did check that it had no water in it.
Because of the iodine treatment, the water does taste a little bit like iodine. This is a small price to pay for potable water. Also, it is important to read the manual. You have to let the water sit in the filter for two hours and you have to flush water through the filter if the filter starts dry.
