Show Description

Filter water faster with minimal pumping effort. This lightweight, ultra-compact, high-flow system filters down to 0.2 micron, removing 99.99% of all bacteria and protozoa. The output is a considerable 2.75L of water per minute.

  • Hollow fibre technology uses proprietary polymer fibres to create a high surface-area filter that allows water to flow quickly through a 0.2 micron effective pore size.
  • A quick-connect adapter attaches the filter to any bottle or reservoir with a standard 63mm threaded opening.
  • The polycarbonate filter body is tough, compact and light in weight.
  • Silicon input hose with pre-filter.
  • Field maintainable, can be easily reconfigured to allow backflushing for flow recovery. No tools required for complete disassembly.
  • Note: These fibres are slightly more brittle than other filter materials and somewhat more susceptible to damage from strong impact. Although the cartridge is protected by the polycarbonate pump body and has been drop-tested to three feet, you should consider carrying a spare cartridge on long trips – they are small, light, and relatively inexpensive. Do not allow the cartridge to freeze after initial use.

Filter type

Water can be treated using various types of filters, chemicals or non-chemical purification methods, or a combination. Filters on their own will not remove viruses as they are too small.

Hollow fibre technology
Output 3L/min
Dimensions 17.8 x 8.3cm
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.

Effective against particulate

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.
