This is quite common if you have a new kettle. Remove the filter from your kettle and fill it 3/4 with water and boil. Once boiled, add 2 tablespoons of bicarbonate of soda and leave to stand overnight. Discard the water then re-boil a couple of times to remove any bicarbonate soda residue.If your kettle is still producing a funny taste, please contact us via email.
