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 technically, it’s true. 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. 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 3 months, have a weakened immune system or were recently sick, according 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.

Types of Baby Bottle Sterilizers

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

There are a few different kinds of bottle sterilizers to consider:

Electric steam. Countertop bottle sterilizers harness the power of electric steam and reach higher temps 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.

Best UV Bottle Sterilizer

Sterilization with UV light is widely used across the medical and pharmaceutical fields, but is still relatively rare in the world of bottle sterilization—primarily because these units tend to be expensive.

The Wabi Baby UV Sterilizer and Dryer earns our top vote in this emerging category. It sanitizes and dries in as little as 30 minutes (with a countdown display to let you know exactly how much time remains on a cycle), has a wide-opening front door for easy access to your bottles and parts, powers down automatically for safety and energy purposes, and works on more than just baby items (you can even throw your phone in there). This bottle sanitizer doesn’t come cheap, but it does pack a big punch.
