Each filter element is sufficient for cleaning about 100 litres of clear water. If
used daily, this will last for about 4 to 6 weeks.
How to change the Cyst Filter
If the water flow gets weaker, you should change the Cyst Filter.
1. Turn the lid clockwise and lift it off together with the filter elements.
2. Using a slight turning motion (see outlinde drawing 1 item 5), pull the Cyst Fil-
ter from the Virustat¨ cartridge (any turning direction)
3. Using a slight turning motion, push the new Cyst Filter firmly, but without
excessive force, onto the Virustat¨ cartridge (see outline drawing 1 item 5)
and make sure that the O-ring is seated correctly (see outlinde drawing 1 below C).
4. To check, push the complete filter against the lid with a slight turning motion
until the filter sits firmly (see outline drawing 1 item 1)
5. Insert the complete filter into the bottle and turn the lid anti-clockwise.

O-rings are seated correctly.
5. Push the complete filter against the lid until it sits firmly.
