Show Description

Great for groups and expedition use, the time-proven and field-proven ceramic filter is combined with an optional carbon stage to remove some chemicals (including iodine and chlorine) as well as tastes and odours. The weight of the rugged polymer and stainless steel housing is somewhat above average, but so is the rapid output of clean water.

  • Housing has an ergonomic grip.
  • Supplied adapter directs water into wide-mouth 1L bottles, or Sigg bottles, to minimize spillage and the risk of cross-contamination.
  • Included measuring gauge is used to check minimum diameter of the ceramic element to determine when replacement is necessary.
  • Flow rate is 1.2L / minute.
  • Effective against all protozoa, and most bacteria, including smaller ones such as campylobacter.
  • Silver-impregnated ceramic filter element. Nominal life of 50,000L (actual yield depends on water quality and clarity).
  • Granular carbon treats up to 400L.

Cartridge life

The life of the filter cartridge is based on the quantity of water you can treat before the cartridge is no longer effective. This does not apply to battery operated or chemical filter systems.

Filter size

A 0.5 micron or smaller filters protozoa and some large bacteria; 0.2 micron or smaller filters smaller bacteria such as campylobacter.

Effective against protozoa

Protozoa are larger than one micron and include cryptosporidium and giardia.

Effective against viruses

Most viruses are in the 0.1 micron size range, but they can be as small as 0.002 microns.

Particulate consists of very small bits and pieces such as dirt or bugs.

Effective against bacteria

Bacteria can cause illnesses such as diarrhea and dysentery and are about 1.0 micron in size, although some can be as small as 0.2 microns.
