All from GRAYL

The young American brand GRAYL produces revolutionary filter bottles that can reliably remove pollutants from polluted water in just a few seconds, such as viruses, bacteria, protozoa, solid particles, heavy metals and chemicals. In addition, the whole process is as simple as a slap. All you have to do is fill the bottle and depress the piston, the rest will be taken care of by a replaceable filter cartridge, which uses an ingenious combination of activated carbon and electrostatic absorption. In an instant, it turns an unattractive liquid into clear water without unpleasant odors and odors. It is an ideal companion for trips around the world and to remote mountain areas.
