There are three ways: –
- If you have a 50cl water bottle, and you have set the timer when you began using it, the timer will remind you to replace your filter after two months.
- If you have a 75cl bottle and have registered with Water-to-Go, an email will be sent to remind you after three months.
- One of the three technologies in our filter (the one which controls the taste and the smell) is carbon. We programme just enough carbon into the filters to expire at either 130 litres (for the 50cl filters) or 200 litres (for the 75cl filters). The filter will still be filtering bacteria, cysts and harmful contaminants; the water after this time will gradually start to taste and smell as it did before using the Water-to-Go bottle. This is a ‘sensory’ prompt for you to change the filter.
