Replacement Cartridges Are The Real Cost
The jug is the one-off purchase. The replacement cartridge is the recurring bill.
UK shoppers should compare cartridge lifespan, multipack pricing, and fit before choosing a jug. A cheap jug with expensive or hard-to-find filters is rarely the best long-term value.
