What Is a Bottle Warmer and Sterilizer in One?

These machines combine the jobs of heating cold milk and sterilizing dirty items, so you can quickly perform the warming and cleaning tasks with the push of a button.

Electric warmers and sterilizers have a heating element that can reach a variety of temperatures depending on the mode you choose to use. In bottle-warming mode, the heater reaches a temperature of about 40 degree Celsius, which is roughly 100 degrees Fahrenheit. When you select the sterilizing mode, the heater reaches a temperature of 100 degrees Celsius, or 212 degrees Fahrenheit, to boil water and create steam.

Do You Need a Bottle Warmer and Bottle Sterilizer?

Since parents have been bottle-feeding their babies without warming or sterilizing machines for many decades, you may wonder if having one more piece of baby equipment is actually necessary.

While it’s true that you could use traditional methods to clean and warm your baby’s bottles, today’s pace of life is generally faster than it was in years past. Taking advantage of equipment that can effectively and easily accomplish daily tasks for you can end up saving you a surprising amount of time and aggravation over the long run.

If you’re still undecided, here are a few of the benefits of using an electric bottle warmer and sterilizer:

Easily heat up a midnight bottle

It’s already difficult to wake up to your hungry baby crying in the night, and simply placing a prepared bottle into the warmer and pushing a button is far easier than fumbling around with heating up water and repeated temperature testing.

Warm a bottle faster

Even if you use the microwave, heating a bowl of water and then placing your baby’s bottle in it is a two-step process that will probably take several minutes at best.

Bottle warmers typically work much faster, and some will bring your bottle to the correct temperature in as little as four minutes.

Reach your desired milk temperature the first time

Even if you follow the same routine for heating water in the microwave or on the stovetop, your bottle’s temperature could still vary from feeding to feeding.

A bottle-warming machine lets you set your desired temperature, so you can count on getting a consistently warm milk every feeding.

Heat your bottle to a safe temperature

Despite your best efforts, you may accidentally overheat your bottle with the water you warm up manually. Most bottle warmers have a temperature cap that prevents the danger of hot spots or destroying breast milk nutrients from overheating.

However, even though electric warmers let you choose your milk temperature, always test a few drops of the warm milk on your own skin to make sure it’s not too hot.

Avoid the danger of boiling water on your stove

Especially since you probably have a baby in your arms most of the day, it makes sense to minimize the chances of steam burns or scalding whenever possible.

Electric bottle sterilizers still use boiling water to clean your bottles and accessories, but they also have a lid that prevents any hot water from splashing out or steam from escaping.

No need for your active supervision

After loading your dirty items and adding the appropriate amount of water, just start the sterilizing cycle and go about the rest of your daily business. After sterilizing, you can leave the clean parts in the machine for the next feeding, or you can lay them out on a towel to dry.

Types of Warmers


Steam warmers heat a small amount of water to boiling, and the resulting steam warms the bottle of milk.

These models usually produce warm milk in a short time, but keep in mind that overheating breast milk or warming it too rapidly may cause some of the vital nutrients to degrade.

Water bath

Submerging a bottle in a bowl of warm water is the method that has stood the test of time.

Electric water bath models typically hold enough water to cover a bottle up the neck, and the machine’s heating element heats the milk indirectly by heating the water around it. Most bottle warmers use the water bath method since gentle heating usually helps preserve the nutritional content of breast milk.

Features to Look For in a Warmer

Time required to reach the set temperature

The time it takes to heat a bottle will always depend on the amount of milk and the type of bottle you use. However, some machines are more efficient than others, so look for a model that has a rapid heating feature if time is an important consideration for you.

Accepts a variety of bottles

Most warmers and sterilizers can accommodate most bottle brands and materials. You don’t want to get an unpleasant surprise the first time you go to use your machine, though, so make sure the model you choose specifically states that it accepts a variety of bottle brands, sizes and types.


If your house is like most, counter space is often in short supply, so look for a machine that has the smallest footprint possible. Models with oval shapes tend to be the most compact.

Additional options

If you plan to stockpile breast milk in the freezer, a warmer that also offers a defrost option can be helpful. If you like the idea of serving your baby warm purees once they start solids, look for a model that also warms portions of baby food.

Temperature hold

The temperature hold feature lets you maintain a warm water bath for up to 24 hours. Most warmers also have an automatic safety shut-off if the machine senses that the water level is too low, so you don’t have to worry about damaging your machine if you forget to add more water.

This feature can be especially helpful for overnight feedings. When the water bath is already at a warm temperature, it will take less time for your refrigerated milk to reach a comfortable temperature. The ability to keep your bottle warm can also be very useful if your baby has a diaper explosion that requires an emergency bath after you’ve already placed the bottle into the warmer.

Caution: Never leave a prepared bottle in the warmer for longer than two hours since bacteria could start to grow in a warm environment. If you forget about a bottle or can’t use it before the two-hour limit, throw the formula or breast milk out right away, and use a clean bottle to prepare a fresh meal.

Types of Sterilizer


An electric sterilizer has a water reservoir and uses electricity to power a heating element that boils the water and creates steam. The hot steam kills pathogens, and most machines turn off automatically when the cleaning cycle is over.


Most microwave sterilizers take the form of plastic bags that use steam to sterilize bottles and related parts. Add a small amount of water and your dirty items to the bag, place the bag into the microwave and set the amount of time recommended by the manufacturer.

Since many microwave sterilizers are very similar and don’t warm a prepared bottle, we won’t cover them in any more detail. Every product reviewed here is an electric model that both warms bottles and sterilizes them.

Features to Look For in a Sterilizer

Accepts different brands of bottles. Just as with a bottle warmer, you don’t want to invest in a sterilizer that won’t accommodate the type of bottles you use. Many electric sterilizers accept most bottles, but it’s always a wise idea to make sure that your preferred brand is on the list before you buy.

Can accommodate bottle accessories. Your baby needs clean nipples and rings just as much as they need a clean bottle. Make sure the sterilizer you choose has space for you to clean dirty accessories along with your bottles.

Turning the machine on, choosing your heating or cleaning mode and adjusting the time are all controlled by buttons on the front panel, so you can easily select your setting even when you’re holding your child.

This warmer’s square shape looks nice, but it is a bit bulkier than other models that have a more compact, rounded shape. The metallic pink shade is soft and should blend in fairly well with most kitchen decor, but you do not have any other color options to choose from.

One of this warmer’s best features is the bright LCD display. Thanks to a real-time temperature displayed in large numbers on the front panel, all it takes is a quick glance to see exactly how warm your baby’s milk is at any given moment. One thing to be aware of is that the display uses the Celsius temperature scale with no option for Fahrenheit.

Bopen 6-in-1 Multifunction

If you prefer a black and white color scheme and geometric shapes, this warmer and sterilizer from Bopen could be a great fit for your style.

In addition to its cool and modern look, you also have six functions to choose from. There are separate warming targets for formula and breast milk, so the delicate nutrients in breast milk are less likely to suffer from overeating. You can also safely thaw a bag or bottle of frozen breast milk, heat baby food, hold a warm water temperature and steam sterilize.

The front panel houses a Celsius temperature display that shows both your set temperature and the current milk temperature, so you can quickly tell how close your bottle is to reaching your desired warmth. Even if you only have one hand free, the front-panel buttons let you easily select your mode and target temperature.

Warming a cold bottle of milk should take somewhere between 10 and 20 minutes, so you may want to make sure to start a bottle a little while before you actually plan to use it or keep your water bath warm with temperature hold.

The square display panel provides an interesting contrast with the rounded case. Even though two bottles from most brands should fit comfortably in this machine, it still has a smaller size that takes up a minimum of counter space.

It only takes a few minutes and a little water in the lower reservoir to sterilize your dirty bottles, but one gripe is that the lack of an accessory tray makes it a little bit harder to clean small pieces.

Manufacturer’s Specs

  • Product Weight: 2.1 pounds
  • Product Dimensions: 7.95 inches long, 5.71 inches wide and 10.87 inches tall
  • Power Source: Standard wall outlet
  • Accommodates Multiple Bottle Brands: Yes

In addition to rapid warming, you can also choose from a few other functions: defrost, baby food warming and sterilizing.

Eccomum 6-in-1 Double Bottle Warmer for Breast Milk

If warming a bottle quickly is the top priority for you, this warmer and sterilizer from Eccomum may be a perfect solution.

This machine combines a warm water bath with a powerful heating element to rapidly warm formula or breast milk, and most bottles should be ready to drink in about three to six minutes. Particularly if your baby wakes up frequently in the night for a bottle, this rapid warming could save you a considerable amount of crying time. You can also choose to use the defrost mode to thaw a bag of frozen milk or warm up baby food.

Since this warmer has a powerful heating element, it’s important that you always use the included tray in whatever mode you choose. Placing a bottle directly on the heating element could damage the bottle or destroy delicate breast milk nutrients by overheating them.

This sterilizer requires just a small amount of water to run a cleaning cycle, but don’t worry that you’ll accidentally run the machine dry and damage it. When the water level gets too low, the machine beeps and automatically turn off. The tray also comes in handy when you want to easily and quickly sterilize small items.

Sankoo 6 in 1 Baby Bottle Warmer, Steam Sterilizer and Food Heater

Bottle sterilizers can be time-saving and convenient products when you feed multiple bottles daily, but they often leave you with the choice of either using clean parts that are still wet or taking the chance of introducing pathogens by towel-drying. Thanks to a post-cleaning drying cycle, you can just take your clean bottles and accessories out of this Sankoo sterilizer and use them immediately.

The warmer function works quickly, and you should be able to have a warm bottle ready in four to six minutes. However, actual milk temperature can vary from one use to another, so always make sure you take the time to check the milk temperature on your own skin with each feeding.

You can check on your milk’s warming progress by glancing at the temperature display screen, and one-handed operation lets you quickly select your function or adjust the target temperature.

In addition to warming formula or breast milk, you can also steam eggs and warm up baby purees when your child is ready for solids. You can choose a low temperature setting to thaw frozen milk or food, but there is not an actual defrost mode available.

Manufacturer’s Specs

  • Product Weight: 2.8 pounds
  • Product Dimensions: 9 inches long, 7.1 inches wide and 9.5 inches tall
  • Power Source: Standard wall outlet
  • Accommodates Multiple Bottle Brands: Yes

  • Fast warming
  • Dries sterilized bottles or parts
Things we don’t like
  • Temperature can be inconsistent
  • No defrost function

J&C Life 5 in 1 Function with Temperature IMD Touch Screen Display

Thanks to a backlit front panel, this warmer and sterilizer lets you get a clear look at each available mode and accurately choose the settings you need. Each function has its own lighted space, so you can clearly see which one you have currently selected. To set a specific target temperature of your choosing, press the up or down buttons to reach the exact setting you want. After five seconds of inactivity, the machine will automatically start running the selected settings.

Two pre-set heating modes give you the option to warm rapidly or slowly. In rapid warming, your bottle should be ready in about four minutes, and slower warming will take several additional minutes. One thing to be aware of is that rapid heating could cause some of the delicate nutrients in breast milk to degrade, so use that mode as sparingly as possible. A temperature hold feature lets you get your water bath ready in advance, so you should be able to primarily use the normal warming mode and preserve nutrients.

Running a steam sterilization cycle takes a small amount of water and a few minutes, and the machine will automatically turn off ten minutes after the cleaning cycle ends.

Additional modes include egg steaming, baby food warming, defrost and dechlorination.

This product has an all-white color and a square shape that closely resembles an actual kitchen appliance, so it should fit in well with most kitchen decor. This machine is a bit larger than some other models, so you will need a bit of extra counter space to house it.

Manufacturer’s Specs

  • Product Weight: 2.15 pounds
