Your young baby’s immune system is not yet strong enough to fight off the common bugs and infections older children and adults don’t even think about, which is why it’s important that all feeding equipment, such as bottles and breast pump parts, be properly cleaned and sterilised before used by babies under the age of twelve months.

The old fashioned technique of boiling bottles in a pot on the stove may be the simplest and most cost effective solution, but it does take considerable time each day which can add up very quickly especially with a young baby to attend to, and can become rather tiresome.

The solution? Bottle sterilisers. When used correctly, they will reliably kill up to 99.9% of common germs and bacteria within minutes.

For bottle fed babies who may go through six to eight bottles a day, they really are a time effective solution as sterilisers can hold and clean multiple bottles at once.

They can also safely sanitise other items such as breast pump parts, dummies and teethers, so you can be confident that commonly mouthed items are as safe and germ free as possible.

Types of bottle sterilisers

  • UV steriliser. Ultra violet rays are used to effectively sterilise and, importantly, dry bottles. UV sterilisers are more expensive than steam sterilisers and also take longer to complete a cycle, however once complete objects will stay in a sterilised state for up to three times longer than steam sterilisers, making it easy to plan ahead.
  • Electric steam steriliser. A small amount of water is placed into these types of sterilisers and electricity is used to generate steam at high enough temperatures to kill bacteria. They are generally quite high in capacity and are suited to families who go through many bottles a day.
  • Microwave steam steriliser. Smaller and more portable than electric sterilisers, microwave steam sterilisers are usually shaped like round platters with removable lids. Simply place your bottles with the appropriate amount of water inside and pop in the microwave which will generate enough heat to create the steam needed to sterilise. As with everything hot from the microwave, be careful of escaping steam when removing the lid.

Let’s now dive into our selection of the best bottle sterilisers in Australia’s market, from the most expensive to the affordable ones.

How to choose a bottle steriliser

Here are some important things to consider before deciding on the best baby steriliser for you.

Frequency of use. How often will you be using your bottle steriliser? You will go through a lot more bottles if you have an exclusively bottlefed newborn compared with a baby who only occasionally takes a bottle of expressed milk. For frequent use, you’ll want to be looking at sterilisers that can handle many bottles at once and are fast to complete a cycle. Electric sterilisers which are turned on with just one press, switch off automatically and run quietly will likely be most suited to you.

Capacity. How many bottles can the steriliser hold at once? You’ll want a steriliser that can easily handle everything and anything you want to throw at it! Want the option to sterilise other items as well as bottles? Maybe a larger capacity steriliser is for you, or consider a model that converts to different sizes depending on your needs.

Size and type of bottles. You want to be sure that the bottles you use will actually fit inside your steriliser. There are so many different types of baby bottles available (take a look at our article here) in all different shapes and sizes, and taller ones may not fit inside some compact, and in particular microwave, sterilisers.

Where the steriliser will be used. A high capacity countertop steriliser with all the bells and whistles sounds great, but can you afford the bench space? Some models take up as much room as coffee machines or even more, and you can expect it to be a permanent fixture of your countertop for your entire bottle feeding journey. Microwave steam sterilisers are smaller and more compact for those short on space, and can even be stored inside the microwave to maximise space. Don’t forget microwave bag sterilisers which are the most space saving of all and are perfect for travelling or for taking to relatives.
