Store Availability

Our team of trekking enthusiasts created this filter to go with your flexible water bottle and filter water while trekking. Fits on the quick stopper.



Filters 99.9999% of bacteria (E. coli, etc.) and 99.9% of protozoons.

Battery life

Filters up to 1000 litres of waters, blocks itself once the limit is reached.


Fits on the quick-open top of the Forclaz flexible 0.6 and 1 L water bottles.


First use

Before first use, rinse the bottle, top and filter with drinking water (3 x 1 minute).
When using for the first time or whenever the filter is dry, fill the bottle with water, screw on the cap and leave to stand for a few minutes to prime the filter. Then draw in 5 quick sips to enable the water to flow.

Directions for use

Rinse your water bottle & filter with drinking water to remove dust and dirt.
Fill the water bottle with fresh water (do not use stagnant water) from the best available source without making the bite valve and top dirty. The clearer and cleaner (no impurities) the water added before filtration, the longer the filter will last.
Avoid drinking any of the water that runs down the side of your bottle while drinking.

Advice for use (continued)

Make sure that the bottle and filter are tightly closed.

The filter will stop allowing water to pass through when it has reached the end of its life.
If you can no longer suck the water, it is time to replace the part that contains the filter.
Thoroughly dry your filter after use.

Filtration system

We chose a micro-filtration technology with a membrane (hollow fibre) that eliminates up to 99.9999% of bacteria (eg : Escherichia coli, Vibrio cholerae, etc.) as well as 99.9% of protozoan parasite cysts (eg: Cryptosporidium parvum, Giardia lamblia), organisms which cause illnesses passed on through water. This greatly reduces the risk of contracting diseases such as diarrhoea, dysentery or giardiasis.

Care tips

After each use, unscrew the cap, rinse the bottle, top and filter with drinking water and allow to dry thoroughly. Before washing the bottle, remove the filter.Do not wash the filter in the dishwasher. Do not try to clean the fibres in the plastic housing. If in doubt, change the filter.
Should you blow into the bite valve and the air passes through the filter, it is defective and must be replaced.


Drinking untreated water and improper use can expose you to harmful micro-organisms and increase the risk of gastrointestinal disorders. To reduce the risks involved, follow the safety guidelines and instructions for use, and find out about the suitability of the water for human consumption in remote areas.
Never use to filter sea water or chemically treated water.Viruses are not filtered by this hollow fibre filter.
Do not drop.
