Allows you to choose between different models and configurations so as to sterilise effectively, conveniently and quickly. The three in one steriliser gives parents options; a full-sized 6 bottle steriliser, or swap the racks to create a smaller compact unit when only a few items need to be sterilised, or for travel out and about, the unit can be converted to a small microwave model. Sterilisation is important for the care and health of the child. In the first year of life, when immune defences are still reduced. Items in the steriliser will remain sterile and safe to use as long as the sterile seal is unbroken. The sanitising power of steam will effectively kill most household germs without the use of harsh chemicals or the risk of damage during boiling. Steam sterilisation leaves no residual odour or flavour on the items sterilised.
