The Katadyn MyBottle virus filter is based on a multistage filter system. The first stage is an integrated 0.3 micron
preliminary glass fiber filter which removes bacteria and protozoa such as giardia and cryptosporidium as well as all particles larger than 0.3 micron.
The second stage is the new ViruPur 3-layer filter medium which adsorbs viruses and minute particles on the basis
of electrokinetic in-depth filtration. This is possible due to the differences in the electric charges of the materials.
Whereas the aluminum-coated glass fibers of the ViruPur filter have a very high positive electrical charge, that
of viruses, bacteria, cysts, and other particles is lower or negative. These differently charged electric fields exert
forces of attraction causing contaminants to be retained on the ViruPur filter and to build up on its surface.
Finally, the water flows through an activated carbon filter which reduces organic contaminants as well as
unpleasant odors and taste.
Bottle holds 20 ounces of water ready to be filtered. Rated use capacity, 26 gallons.
Integrated counter in cap to keep track of fills. Replacement filters available.
