7 Best Bottle Sterilizers to Kill Germs Fast

During the first year of a baby's life, parents have a lot to worry about, not the least of which is that a baby's immune system is the most fragile at this time. Camille Sabella, M.D., Director of the Center for Pediatric Infectious Diseases at Cleveland Clinic Children’s, states that “an infant’s immune system doesn’t mature until around 2 to 3 months.” While there's not much one can do to avoid exposure to household germs altogether, there certainly are steps to take to help ensure they are bacteria-free. Enter the bottle sterilizer – these nifty gadgets make it easy to sanitize (99.9%) bottles, nipples, toys, pump parts, and anything the baby may put into their mouth (which is, like, everything.)

The engineering experts at the Good Housekeeping Institute test all of the latest and greatest gadgets for all of your parenting needs, from baby monitors to kid's toys. To find the best baby bottle sterilizers, our engineers in the Little Lab considered how easy they were to use, how long they took to operate, how easy they were to clean, and the number of bottles they can hold. Over the past four years, our engineering pros (and parents!) logged tens of thousands of hours sterilizing bottles and accessories! We also we relied on user reviews and feedback to pick the top-rated sterilizers. Here are our top-picks for saying bye-bye to germs fast:

Do I really need a bottle sterilizer?

While it is a personal choice for your family, the Centers for Disease Control and Prevention (CDC) recommends sterilizing bottles and parts once a day, especially for babies younger than three months, born prematurely, or have a weakened immune system. Although not mandatory, it is recommended to always sterilize new bottles before using them and if your doctor has recommended sterilizing bottles between feedings, you might like the convenience of being able to load and run a sterilizer without needing to boil water every time, especially if you have multiple babies.

Hand washing bottles with hot water and soap or running them through the dishwasher gives them a good cleaning but may not appropriately sanitize, while most sanitizers claim to eliminate 99.9% of bacteria, helping to alleviate the potential for serious illness. You can certainly sanitize your bottles using boiling water on the stovetop, but it does get tedious and is time-consuming. While you don't need a dedicated machine to sanitize, having a bottle sterilizer on hand certainly provides convenience, kills germs, and adds some peace of mind. We say that is a win-win for all.

If budget isn't a factor, this electric sterilizer and dryer combo does it all. According to the manufacturer, you can sterilize up to 8 bottles, plus accessories, and kill 99.9% of harmful bacteria in 8-15 minutes. It offers three different functions with the simple touch of a button: sterilizing (in as little as eight minutes), drying (leaving bottles condensation-free and ready for use from 30 minutes to 60 minutes), and descaling (taking care of hard water and calcium deposits, a common issue with steam bottle sterilizers). It has a smart sensor that shuts the unit off automatically when it's done sterilizing, and it also has a countdown timer so you can track how much longer it will take. Bottles will stay clean for up to 24 hours with a closed lid, so you can set it up the night before and wake up to sparkling bottles ready for your baby.

When choosing your sterilizer, consider how many bottles you'll want to clean at once, the cost, how much counter space you have, and if it would be easier to have an all-in-one device that dries and stores or a simple unit that fits in the microwave when you need things cleaned. Some also include dryers, for an added bonus.

If you choose to use a bottle sterilizer for your baby's bottles, there are two ways to go about it — microwave or electric. Both types use the steam to kill approximately 99.9% of harmful bacteria in just a few minutes, so it's simply a matter of personal preference which one you should choose, and they are both safe and effective given the right devices. Here's a breakdown:

• Electric steamer sterilizer: Simply plug it in and let the machine do all the work. In an electric sterilizer, the bottles and parts are cleaned at a high temperature to produce steam. Electric sterilizers come in many shapes and sizes, depending on your needs and countertop real-estate.
• Microwave sterilizer: Easy and effective, microwave sterilizers can efficiently sanitize baby bottles and accessories in under two minutes. They come either in steam bags or in plastic containers. Just add water, and pop it right into the microwave for quick sanitizing.
