The Bad

Unlike some UV sanitizers, it’s not suggested to use electronics in this item.

Otherwise, beyond not being portable, the only issue is bulbs needing replacement after only a few months. 

3. Philips AVENT Microwave Steam Sterilizer

For moms who want fast and affordable. try Philips AVENT Microwave Steam Sterilizer to sanitize your baby bottles in two minutes.

Because the sterilizer goes in the microwave, it won’t take up any counter space. Store either in the microwave or in a cabinet if need be. 

Finally, the container is BPA free and works perfectly with Philips AVENT bottles, but will also work with similarly sized options. Fit four bottles in at the same time. If you need to and have space, you can pack the container up and take it with you to use anywhere where there is a microwave. 

We’ve got a comparison of Tommee Tippee vs AVENT bottles.

Baby Brezza Baby Bottle Sterilizer and Dryer Machine - Electric Steam Sterilization - Universal Fit - Pacifiers, Glass, Plastic, and Newborn Feeding Bottles

The Bad

Plastic is only so sturdy. It can break down and deteriorate with use.

Some customers complain that the device doesn’t save them any time or make them feel like the bottles are actually sanitized. For those people – me included – who do not trust microwaved this is not the best product for you. Microwaves tend to overheat in some spots and not enough in others.

Also, the bottles do not stay upright and tend to fall over. 

4. Papablic Baby Bottle Electric Steam Sterilizer and Dryer

Baby Brezza Baby Bottle Sterilizer and Dryer Machine - Electric Steam Sterilization - Universal Fit - Pacifiers, Glass, Plastic, and Newborn Feeding Bottles


The Papablic Baby Bottle Electric Steam Sterilizer and Dryer won’t take up a huge portion of your counter space as its thinner than it looks.

Even better, it uses steam to clean and sterilize bottles for a more encompassing cleaning process. 

The Good 

Steam disinfects at a higher temperature meaning this device will kill more germs than your dishwasher. Like the other sterilizers listed, this one also kills over 99% of germs. Twist the dial and try all three settings, sanitize, dry, and extra dry.

The electric sterilizer includes a large compartment for bottles and smaller stackable basket for bottle nipples, pacifiers, and toys. Also, the device works in just six minutes. 

Lastly, with three stacking options, you can customize what you need to sanitize for up to 11 bottles and accessories. You will also love storing bottles off the counter and in the device for a more sterile environment for over 12 hours.

The unit is also easy to clean and use which makes this a great option for most families. 

Munchkin Steam Guard Microwave Sterilizer

The Bad

To use steam, the device requires you to add some water to a tank, similar to a humidifier, so you will need to descale the device to ensure less calcium deposit. If you do not clean often, the device and get rust which is no fun and not sanitary.

Also, water can leak out of the bottom creating a mess on the counter.

Finally, the unit can take up to an hour to fully dry depending on what setting. Not great in the middle of the night with a hungry baby. Plan ahead. 

5. Grownsy Baby Bottle Warmer and Sterilizer

Gourmia Jr. Digital Baby Bottle Sterilizer and Dryer, 8-Bottle Capacity, Digital Display, HEPA Filter, JBS200, ETL-Certified

The Good 

Yes, this device will sterilize your baby bottles but will also defrost and warm breast milk, heat formula, keep bottles warm and heat infant food. That’s a whole lot of functions (6 total) for one machine and all for a very reasonable price.

The unit is also quite small, just big enough for two bottles, so the footprint in your kitchen will be smaller too. Just don’t put it next to the coffee maker or you might end up with formula and your baby with coffee! 

Beyond all the other functions, you can choose to fast warm or slow warm a bottle. Use the touch screen to read the real-time temperature. All the other functions are easy to read on screen as well to prevent drying out, or overheating.

Gourmia Jr. Digital Baby Bottle Sterilizer and Dryer, 8-Bottle Capacity, Digital Display, HEPA Filter, JBS200, ETL-Certified

The Bad

A few customers complained of leaks which is normal for most steaming devices and the need to add water for each cycle. Otherwise, the only real complaint is the device can only take care of two bottles at a time instead of multiple like the other sterilizers on this list. 

Also, the instructions are confusing because they seem to have been translated poorly into English. Fortunately, most of the features are pretty intuitive.

6. Gourmia Jr. Baby Bottle Sterilizer

Gourmia Jr. Digital Baby Bottle Sterilizer and Dryer, 8-Bottle Capacity, Digital Display, HEPA Filter, JBS200, ETL-Certified

The Bad

No customer complaints with this model! Unlike some of the other models though, this one only holds 7 bottles but those do include multiple styles, like the best reflux bottles

The round shape can be bulky on countertops, especially in smaller kitchens. If you need a smaller model definitely try the J&C Life model above.

Added accessories like tongs and a measuring cup for the water are included. It is also nice that the way the bottles are inserted allow steam to blow directly in the bottle.

9. Baby Brezza Bottle Sterilizer and Dryer

Baby Brezza Baby Bottle Sterilizer and Dryer Machine - Electric Steam Sterilization - Universal Fit - Pacifiers, Glass, Plastic, and Newborn Feeding Bottles

Though the Baby Brezza Bottle Sterilizer and Dryer is one of the more expensive sterilizers, it is the only one on this list with a drying function. It is also very compact, allowing you to sterilize bottles and attachments without taking up a lot of space (or time).

The Brezza baby bottle sterilizer is constructed of BPA-free plastic and uses a stainless steel heating tray. The stainless steel prevents rust that is common with some other models.

An LCD control panel makes it easy to see how much longer your bottles will take.

10. Munchkin Steam Guard Microwave Sterilizer

Munchkin Steam Guard Microwave Sterilizer

The Munchkin Steam Guard Microwave Sterilizer is affordable and simple to use. It also features an open-away design and comes with heat-resistant tongs and a removable basket, minimizing the risk of burns.

The Munchkin microwave sterilizer has a compact design, so it holds fewer bottles than the electric models. Its size is necessary for fitting inside standard microwaves, though. It can sterilize four small bottles and pump parts at once.

Even though it only takes minutes in the microwave, you still have to let the product sit for ten minutes after the heating cycle ends. This can be difficult to time when you are busy with your little one, especially when you need the bottles cleaned now.

One major downside is the way the lid of the sterilizer is designed. A handle pops up when the bottles are ready, but it is not secure enough to pull the warmer out of the microwave without losing water. Instead, you have to support the warmer on a towel in your opposite hand as you remove it from the microwave. Otherwise, there is a risk of spilling the warmer or burning yourself from the steam.


  • Opens away from you to prevent burns
  • Tongs included for grabbing sterilized parts
  • Fits most standard microwaves
  • Roomier than microwaveable sterilizing bags


  • Need to set a secondary timer to know when ten minutes have passed
  • Handle is poorly designed

FAQ’s about Bottle Sterilizers 

Do I need a bottle sterilizer?

Bottle sterilizers are one of those optional parenting options. You do not necessarily need a bottle warmer, however, it does make sterilizing your little one’s bottles a lot easier and more convenient. There is still the alternative option of using boiling water as a sterilization method. If you are on the fence, here are some benefits of bottle sterilizers:

  • There is less risk of burning yourself when removing items from boiling water
  • It is faster since you do not have to boil water
  • It helps you avoid warping and damage that can happen when boiling
  • Sterilizing is more thorough than disinfecting with boiling water

Is sterilizing my baby’s bottles necessary?

Yes, sterilizing your baby’s bottles is necessary. The high infant mortality rate prior to the early 1900s was caused by the lack of sterilization. According to the history of baby bottles, those used in the 1800s featured long rubber tubes that were nearly impossible to clean.

The situation was made worse by a Victorian woman named Isabella Beeton. Beeton had written a popular book among Victorian women of the time, who considered the book the standard for household management. Among the many tips in Mrs. Beeton’s Household Management was the recommendation that women avoid washing the nipple for their baby’s bottle for 2-3 weeks at a timea practice that resulted in the growth of bacteria until it reached deadly levels.

Mrs. Beeton’s advice was wrong. As researchers uncovered the link between the bacteria left behind from mother’s milk and the formula’ used during the time, the bottles were discontinued and new sterilizing practices were advised.

Today, the traditional method for boiling bottles involves submerging all nipples, caps, bottles, and other equipment in boiling water for at least five minutes to kill the germs. It is necessary to sterilize bottles to prevent the build-up of deadly bacteria, especially in hard-to-reach areas of the bottle that might not be as easy to wash.

What features should I look for in a bottle sterilizer?

As you consider which bottle sterilizer is best for you and your baby, here are a few things to keep in mind:

  • Design – There are several styles of bottle warmer. Cold water sterilizers require you to purchase sterilizing liquid or tablets to add to the water, while most others use heat as a sanitization method. Some are designed to work with a battery, while others require a power source. There are also sterilizers that work with your microwave. Recently, UV bottle sterilizers have been developed. These are portable and use UV rays to sterilize.
  • Speed – Cold water sterilizers can take up to half an hour, while most other electric sterilizers finish within ten minutes. Time is important since one of the major disadvantages to boiling is waiting for the pot of water to warm up.
  • Effectiveness – Unless a bottler sterilizer is cleaning your little one’s bottles properly, there is no point in it. Consider your unique needs before deciding if a bottle sterilizer is a good fit for your family.
  • Convenience – Bottle sterilizers are made to make life more convenient for parents. If they have small parts or are difficult to use, they are going to end up sitting on a shelf collecting dust while you boil bottles.
  • Size – A compact bottle sterilizer will not take as much space, however, you will not be able to clean as many bottles at once. Overloading the bottle sterilizer is also a problem, since the bottles may not be as sterilized.

Do I need to wash bottles before putting them in the sterilizer?

If you put bottles with old formula or milk in the sterilizer, you are going to contaminate the sterilization area. You should always wash bottles with hot water and soap before sterilizing them. Rinse them thoroughly, too. You can start the sterilization process once they are clean.

Does every baby need sterilized bottles?

No. Many moms live just fine without sterilizing bottles.

But some moms may want them to be extra careful. A sick baby is no fun at all. Not to mention small babies cannot fend off illness as well as older children.

If you have a preemie or a sickly baby, you may want to consider one. If you, like me, find housework to be a bit daunting, you may want to invest as germs love to find babies. 

How often do I need to descale a steam sanitizer?

The answer depends on how often use the sanitizer. If you use the device every day than you will want to descale with vinegar once a week. If you only use bottles to supplement then you may only need to descale once a month.

Keep an eye on the metal plate and the bottom part of the unit for build-up and clean more often accordingly. 

Can’t I just boil the bottles to kill germs?

Yes, you can, but it’s a lot more work! Boiling requires babysitting the pot at the stove and then pulling the bottles out without burning yourself. Sterilizers do all the work so you don’t have to watch a pot boil or burn yourself pulling bottles out.

Also, most sterilizers are multi-functional now and provide other added benefits than just sanitizing bottles. 

Final Thoughts 

Sterilizers may not be necessary for every home but can be valuable in reducing germs near your baby and also are often multi-functional to help warm bottles and even clean breast pump accessories making them a great purchase even for breastfeeding moms.

I prefer dedicated baby sanitizers like the Gourmia Jr. Baby Bottle Sterilizer to sterilize bottles and pacifiers.
