Rating : - Katadyn Pocket Water Microfilter
There are trade offs among weight, size, and cost with the water filters I have used. This one is more expensive, smaller, and packs easier, but is a little heavier for its size due to the nature and quality of the materials utilized. Others are lower priced and made of lighter plastic materials, but occupy more space. I have used this on three and four day hikes. It performs as one would expect. Prepare to do a good deal of pumping to produce your water. I gave it four stars only because it would be nicer if the design incorporated hoses with a greater diameter to allow more water to be filtered with each pump.
