Do I Need a Bottle Sterilizer?

Sterilizing bottles and other items that find their way into baby’s mouth (in other words, everything) might seem like one of those steps you can skip—and since the majority of developed countries use treated municipal water, washing with warm, soapy water (or popping them in the dishwasher) after each use usually does the trick, according to the American Academy of Pediatrics (AAP). Gina Posner, MD, a board-certified pediatrician in Fountain Valley, California, concurs, noting that while sterilization is better for premature babies, for most feedings using a sterilizer is about the comfort of an extra level of cleanliness. “But soap and water is just fine too,” she adds.

Music to a tired parent’s ears, right? But don’t write off bottle sterilizers just yet.

Taking the extra effort to make bottles, feeding parts and toys germ- and bacteria-free is still important—especially for babies who were born prematurely or are younger than 2 months, have a weakened immune system or were recently sick, according to the CDC. Even if those criteria don’t apply to your little one, sanitizing is never a bad idea—and with any of these 10 top-of-the-line bottle sterilizers, it’s easier than ever.

Before you start shopping around for the best bottle sterilizer, it’s important to understand what qualifies as sterilizing (spoiler alert: It’s not just cleaning with extra-hot water), as well as the different sterilization methods.

Washing a bottle with soap and water after a feeding is great for getting it clean, but it won’t rid them of household germs and bacteria the way that sterilizing does. To get a fully sterile bottle, you can boil it for five minutes or pop it into the dishwasher if you have one that uses hot water and a heated drying cycle. Otherwise, you’ll want to buy a top-notch bottle sterilizer.

Types of Bottle Sanitizers

There’s more than one way to get baby’s bottles clean with the help of a sterilizer. Consider these different types:

Electric steam. Countertop bottle sterilizers harness the power of electric steam and reach temperatures higher than boiling water to eradicate germs and bacteria. They tend to be the quickest and easiest option, especially if you plan on sterilizing items frequently.

Microwave steam. Microwave bottle sterilizers also use the power of steam, but are a great choice for those who are tight on space or looking for an affordable alternative to electric steam sterilizers.

UV light. Ultraviolet light disinfection is widely used in the dental, medical and pharmaceutical fields and kills bacteria and germs by altering their chromosomes and preventing cell division. Bottle sterilizers are beginning to incorporate this effective, high-tech method, which—bonus!—eliminates the mess of steam sterilization.

Now that you know the ins and outs of sterilizing, you can decide which method is most appropriate for your family and pick a bottle sterilizer accordingly. Need some helpful hints? We’ve rounded up the best bottle sterilizers for every need.
