Katadyn MyBottle Purifier Bottle



Show Description

Contained in a water bottle, this purification system is convenient for backpackers, day trippers, and other travellers. Just add water. The system works in three stages – a large cyst filter removes protozoa, an iodine resin cartridge kills smaller bacteria and inactivates viruses, and a carbon post-filter removes chemicals, tastes, and odours.

  • Bottle is made of food grade polyethylene.
  • Effective against protozoa, bacteria, and viruses.
  • The cartridge and filters are independently replaceable and each one lasts for about 100 litres of water.
  • Ergonomic drinking valve opens with a flick of the finger.
  • Fits into bike bottle holders and bottle belts.
  • Due to residual iodine, this product is not for use by pregnant women or people with existing iodine sensitivities.

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.

Glass-fibre filter w/carbon core
Dimensions 26.5 x 8.5cm
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.

Effective against protozoa

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

Effective against viruses

Most viruses are in the 1.0 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.
