The Vario microfilter is an amazingly compact water filter mainly used in the outdoors. It is created by Katadyn. The point of the Vario filter is to make dirty water pure enough to drink quickly so that you are not slowed down. This item is unique because it offers two different types of filters for different water conditions. There is a 'fast flow' or a 'long life' option. Also, the Vario microfilter is able to pump up to two liters per minute. The main competition for the Vario Microfilter is the MSR MiniWorks water filter. The two filters are strikingly similar.

Katadyn is water filter company that was started in Switzerland. Katadyn has been creating personalized water filters since 1928 and has now become the global number one in producing water purification systems. Katadyn has been making products for militaries, health organizations, and outdoor adventures all over the world.

I recently went on a camping trip and I used the Vario Microfilter the entire trip to supply me with water. It is small enough, about the size of a 32 ounce nalgene bottle, and light enough, just under a pound, to go everywhere I went in my backpack. It is one of the easiest filters I have ever used. With a simple twist of the top you can change it from 'fast flow' to 'long life' and back again. I enjoyed using the Vario Microfilter because it was so simple. All I had to do was screw the bottom onto my nalgene (it fits most bottles that size), stick the hose in the water I wanted to purify, and start pumping. In an incredibly short time my bottle was completely full. Also, the Vario Microfilter is not difficult to clean. It is very easy to take apart and put back together. All the supplies needed to clean the tool are included in the box.

The only thing that I did not enjoy about the Vario was the lack of information about getting started with it. After you figure out how everything works it is incredibly simple to use. However, I would suggest becoming comfortable with the water filter in your sink or bathtub before you head out in the woods and try it out there. It took me a little while to figure it out at first. It would have been handy if there was a 'how to' book included in the package. Other than that I think the tool is an amazing piece of work.

I would suggest the water filter to anyone who spends a good amount of time camping and hiking. It is rather expensive, around $80 but if used often will make up for every cent and many more. You will not have to worry about lugging water around anymore.
