£18 a month?!?!?!
I thought the carbon filter on my boiling tap was expensive at about £30 every 6 months. In reality I change it every 12-15 months.
Yup not the cheapest but £18 is an inconsequential amount in the grand scheme of our finances. The machine is fantastic, unlimited supply of refrigerated filtered water and we replaced our kettle with the boiling water it produces.
