Since sterilizing your baby's bottles, teethers, and pacifiers takes more time than the regular cleaning, a highly-rated baby bottle sterilizer is a must-have for new parents. While there plenty of options when it comes to sterilizing—including boiling them in water by hand—any machine that does the work for you or has another feature built like a dryer or warmer is a guaranteed time-saver.

Not every doctor will recommend routine bottle sterilization, but for newborns, sterilizing bottles once a week will make feeding safer. If anything, it will make you feel better knowing you can give your baby's bottles, accessories, and pump parts a deep clean when you need it.

Perfect for your baby registry, the best baby bottle sterilizers will clean quickly, quietly, and are easy to use.

Below, we outline the benefits and unique features of our favorite bottle sterilizers in 2021.

What to Look for in a Baby Bottle Sterilizer 


Depending on your needs, look at how many bottles (and accessories) will fit in the sterilizer you want to buy. Some are smaller or portable, like Dr. Brown’s Deluxe Bottle Warmer & Sterilizer, but most should be able to accommodate enough bottles for a day of feeding. 

Bottle Compatibility

Make sure the sterilizer you choose will work with the bottle brand your baby likes. Most will accommodate any brand of bottles but some, like the Philips Avent 3-in-1 Electric Steam Sterilizer, are built with features that specifically cater to a certain bottle brand. 

Cleaning Time

Take a look at how long the sterilizer you like will take to clean your bottles. Most cycle times are pretty short, but some have built-in dryers that can take longer. 


As your baby grows, your sterilizing needs will change. To get the most out of your machine, you might want to look for one that can accommodate accessories like teethers, pacifiers, sippy cups, or pump parts. Similar, portable bottle steamer bags are great for travel or if you don’t have enough storage space. 


How often to sterilize baby bottles? 

After a bottle and nipple's first sterilization, a good cleaning in hot, soapy water is sufficient. However, if you prefer to sterilize throughout your baby’s first year, once a week is plenty. Also, it’s a good idea to sterilize bottles and pacifiers after your child has been sick.

When to stop sterilizing baby bottles?

Unless you’re cleaning a bottle for the very first time, you don’t really need to routinely sterilize your baby bottles. That said, the Centers for Disease Control and Prevention (CDC) recommends sterilizing once a day if your baby is less than 3 months old or was born premature or with a weakened immune system.
