However, you’ve got to be smart to ensure you buy a quality model that will meet your specific needs and requirements.

Look for these crucial aspects in the sterilizer to help you make the best choice easily and quickly:

If asked, I’d go Philips AVENT anytime, any day! Honestly, this company has won my heart—and those of many other parents all over the globe)—for their excellent quality, functionality, cost—everything! Other brands worth a mention include the Tommee Tippee, Dr. Brown’s, and Munchkin.
  • Cost: It’s also essential that you come up with a budget of how much you’re willing to spend that brand new microwave sterilizer for your baby bottles. Just like any other baby product you’ve bought before, the cost of these sterilizers varies as you move from one model to the next. A decent microwave baby bottle microwave sterilizer should cost you approx. $20 bucks.
  • Versatility: If you come across a microwave that enables you to disinfect additional baby items—like the breast pump parts, small toys, pacifiers, etc., –consider it as a potential pick. Without a single doubt, such a model will take the overall health of your baby even higher while saving you the extra cash you might need to spend on a sterilizer for the other items.

As we’ve mentioned before, the microwave sterilizer employs high-temperature steam that’s unforgiving to the disease-causing germs on your baby bottles. The water you put in the sterilizer is boiled and turned into steam which then cleanses your bottles.

The ONLY thing you need to do to ensure your sterilizer is safe for disinfecting your baby bottles is strictly following the manufacturer directions for use.

Microwave or Electric Bottle Sterilizer- Which One To Buy?

which is better electric bottle sterilizer or microwaveBoth the microwave and electric sterilizers are designed to help you sterilize your baby bottles.

In fact, both of them are highly recommended methods given their efficiency at killing the bacteria and germs harboring your baby bottles.

The MAIN question is…

Microwave vs Electric Sterilizer— which one should you choose over the other?

The truth about the two devices is that each comes with its own set of ups and downs.

For the electric baby bottle sterilizer:

The Good: employs high heat steam to kill bacteria effectively | uses fast sterilization cycles | extremely easy to operate for anyone | some of them not only clean but also dry and deodorize your bottles

The Bad: most are usually bulky; might take up larger space in your house | they tend to come with higher pricetags

For the microwave baby bottle sterilizer:

The Good: they employ high heat steam to kill bacteria effectively | they come at incredibly low costs | they’re also super-fast, sterilize your bottles in under 5 minutes

The Bad: No dryer; you’ll need to air-dry your bottles afterward

Our Verdict: both electric and microwave sterilizers do their intended job perfectly well. The MAIN difference between them is the cost… though the gap isn’t that significant. I, therefore, believe that the best type of sterilizer for you should be based on your personal preferences. If you have limited kitchen space and a tight budget, I suggest that you buy a microwave bottle sterilizer. 

The Best Microwave Bottle Sterilizer Is…

We can confidently tell you that the best microwave bottle sterilizer you’ll ever have is the Philips AVENT Microwave Steam Sterilizer. This product is super-easy to use and will eliminate up to 99.9% of harmful bacteria and germs in your bottles in 2 minutes only. It’s also compact and lightweight, so it’s not the type that fills your kitchen.

And you know what? It comes with an unbelievably low price tag compared to the other high-end models with similar features and quality.

Just a quick reminder, sterilizing your baby bottles is an impart practice that will significantly reduce the chances of your little one’s weak immune system from getting easily infected.
