It is important that the sterilizer has a wide enough area to accommodate bottles with different shapes and sizes. You do not want to purchase a sterilizer and find out that it doesn’t fit most of your baby bottles.
How often do you plan on using the sterilizer? If you use it every day, you will need a sterilizer with a fast cycle time; if not, then one with a slow cycle would be sufficient.
There are two types of water sources- tap water and distilled water. Tap water can be stored in the tank which can save you from having to bring distilled water from home each time the sterilizers need refilling.
