No. The filter is good for 130 litres when using the 50cl Water bottle or 200 litres for the 75cl water bottle. In practical terms, this means that you can fill up the 50cl Water bottle 3-4 times a day, every day and the filter will last 2 months. Using the 75cl water bottle 2-3 times a day the filter will last for 3 months. If you stop using your Water-to-Go filter it will dry out and will need to be re-activated.
To reactivate it just fill the bottle up and turn it upside down, submerging the filter for 15 minutes. Then gently squeeze out the contents until the water runs clear.
We have created a short video showing how to activate your filter.
