Especially in the first year of life, hygiene is extremely important to protect babies from bacteria. Sterilizers (also called vaporizers) kill germs in baby bottles, on nipples, teething rings and breast pumps with hot steam - they disinfect without any chemicals. In the past, baby bottles had to be laboriously boiled. Sterilizers simplify and speed up this process considerably. On average, boiling takes only six minutes. If you use a sterilizer for the microwave, the process is even faster, depending on the wattage of the microwave. With many models, the contents remain sterile for 24 hours with the lid unopened. When choosing your sterilizer, make sure that the capacity is sufficient for the number of bottles you want to disinfect at the same time.
