Maintenance
A filter every six months. That is about it.
An indicator on the tap tells you when the filter is nearing the end of its life. The plans send you what you need at the right time, with no commitment.

Good to know
How often should I change the filter?
Roughly every 6 months for a household of 3–4 (more often for larger households, less often if you live alone). An indicator on the tap turns orange, then red: no need to keep count.
Does it need descaling?
Once a year in hard-water areas. 30 minutes, either yourself (video tutorial) or by a partner technician, included in the Standard and Plus plans.
Can I buy consumables elsewhere?
CO₂ cylinders, yes (standard size). Filters, no: they are designed for this tap (€35 each, or included in a plan).
Can I use CO₂ cylinders from the shops?
Yes: they are standard 425 g cylinders, SodaStream-compatible. Choose ones certified for food use.
