The Hiker Pro Microfilter from Katadyn is small, weighs a mere 310 grams, and thanks to its large filter area delivers an outstanding pumping performance. It reliably eliminates bacteria, cysts, and sediments from water. The filter is very easy to clean on trips thanks to its cleanable filter protector. The filter protector also appreciably extends the life of the 0.3 micron glassfiber filter cartridge. Its active carbon filling improves the taste of water and eliminates odors.
