Water Filter Replacement Cartridges

Price: from £30.00

Water Filter Replacement Cartridges are available to buy individually or as part of our Cartridge Replacement Plan where we send you a replacement cartridge every 6 months.

The Advanced filter, features our Twist ‘N’ Lok fitting system, which will work with any of our water filter systems and is now even smaller – just 50% of the 2009 model size, with no reduction in capacity!

In addition to the myriad benefits of the Advanced Water Filtration kit, the Premium Advanced Model utilises Scaleguard technology to help those in hard water areas. By reducing limescale build up, it will lengthen the life of your kettle and improve the taste of your hot beverages!

Do you live in a Hard Water Area? Why not check out our Hard Water Map.
