The pocket filter has a pore size of 0.1 micrometer, while the smallest bacteria is
larger than 0.2 micrometer. The filter has a very high effectiveness in removing bacteria
(for example, Campylobacter, Salmonella, Shigella, E. coli) and in removing protozoa
(for example, Cryptosporidium, Giardia).
Minerals are not removed from the water by the pocket filter.
No need for hand pressure as water flows freely through the patented pocket filter when attached to a water bottle.
The pocket filter is totally mobile, it can be used while traveling, camping, mountain climbing, at school, at home, in a hotel and dormitory.
