The Peak Water filter disc will have a different capacity based on the setting used and the hardness of your water – with hard water depleting the exchange resins more quickly. The filter disc capacity is not automated and will require monitoring by the user.
We’re currently in the process of finalising the exact combination and volumes of the exchange resins in Peak Water filter discs. Our goal is to be able to achieve 100 litres of filtered water on the hardest setting.
As per EU regulation – and as a requirement for hygiene – the filter disc has a set life of two months once usage begins. All water filter jugs are exposed to the open air through normal use and this regulation is in place to prevent bacteria build-up. The regulation is more of an indicator of ‘freshness’ than actual capacity. When using the jug, you should consider both the lifetime capacity of the filter disc and its freshness.
