Water filter Sawyer S1 Foam Filter

The Sawyer S1 Foam Filter water filter allows you to drink clean water in any situation. The foam filter removes almost all impurities found in fresh water, while also improving its taste and smell. Sawyer systems combine a patented foam membrane in a durable silicone bottle with a 0.6 litre capacity and a hollow-fibre filter.

The Sawyer Micro Squeeze filter is attached to the bottle. The PointONE technology used in this filter has an absolute pore size of 0.1 micron. Thanks to this, it filters out 99.99999% of all harmful bacteria such as salmonella, cholera, E. coli, etc.

We recommend filling and drying the bottle only through the smaller opening where the Sawyer filter is attached. If you remove the reduction cap, it must be resealed before you can use the bottle again. If you do not do this, unfiltered water may pass through and contaminate the drinking water!

The S1 filtration system removes bacteria, protozoa, cysts, chemicals and pesticides from the water. The filter has a service life of 1600 uses. Its only potential weakness is its sensitivity to frost. If the filter is damp and freezes, the filtration membranes may be damaged and the filtration becomes ineffective.

The bottle is 25 cm long with a diameter of 6.5 cm. The filter has a diameter of 3.5 cm and a length of 11 cm.
