We recommend using distilled water as this helps to prevent/reduce any limescale build-up. If you use regular tap water, or filtered water you may find limescale deposits form so regular descaling will be needed to ensure your Formula Pro Advanced continues to work correctly.
Bottled water is not recommended for making up infant formula feeds for your baby. This is because it is not usually sterile and may contain too much salt (sodium) or sulphate.
