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
Dimensions 18.5 x 3.5cm
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.
