Everything You Need to Know About Sterilizers for Baby Bottles

by FrankJan 25th, 20226 mins read


At one time, mothers sterilized baby bottles by boiling them in water then letting them air dry. It wasn’t complex but it was time-consuming, and if you didn’t do it just right, you’d have to start all over and do it again. These days, however, things are different. In fact, you don’t even have to do much yourself to sterilize your baby bottles, because there are UV sterilizers and steam sterilizers that will do the work for you.

UV and steam sterilizers are devices that you essentially just place the bottles in, then you set a timer and forget about them. Not only is it easier than the old-fashioned way and less time-consuming, but it also does a much better job because it gets into all of the nooks and crannies to make sure the job is done to perfection.

Everything You Need to Know About Sterilizers for Baby Bottles

How Do You Sterilize Baby Bottles?

Whether you choose a UV sterilizer or a steam sterilizer for your baby bottles, the process is roughly the same. Most of these devices look like large boxes or crates and they work via either a UV sterilizing light or a steaming unit. The UV devices are made to shut the light off as soon as the top part opens the partway to protect your eyes from the UV rays, which can be harmful.

To operate either type of sterilizer, you simply place the bottles and bottle tops inside of the unit and press a button. The sterilizing itself can take anywhere from a few minutes to about 20 minutes, not including drying time. Each device will have instructions telling you how long to leave the bottles in the sterilizer, but the fact that you can go off and take care of other tasks while the sterilizer does the hard work for you is a big drawing card for these products.

Both UV and steam sterilizers can have other capabilities as well, such as the ability to dry and descale the bottles, the latter being especially useful if you live in a place that has hard water. They are also great devices to own because they are usually large enough to sterilize other items, such as your cell phone, keys, jewelry, and even other baby items.

UV Sterilizer Versus Steam Sterilizer for Baby Bottles

If you’re trying to decide between a UV sterilizer and a steam sterilizer, it’s best to compare several different aspects of each one. These include:

  1. Convenience: both sterilizers are convenient because they both work with the touch of a button, but if you’re trying to decide which one is right for you, you might want to research the amount of time it takes to sterilize your items if that is important to you.
  2. Cost: UV sterilizers usually cost more than steam sterilizers, but you should also keep in mind that UV sterilizers usually accommodate many more items than steam sterilizers do. Steam sterilizers are usually made just for baby bottles.
  3. Functions: both sterilizers offer a variety of functions besides just sterilizing, so look for the functions that are most important to you.
  4. Size/Capacity: this category is subjective because both UV and steam sterilizers come in many different sizes and designs. As a general rule, though, UV sterilizers tend to be bigger than the steam types simply because they are made to accommodate a variety of items.

In the end, you’d do well to decide which features are most important to you and make your decision based on that.

    Everyone has a budget, but sterilizers for baby bottles come in all price ranges, which means you should be able to find one you can afford.

  2. Drying ability

    Sterilizing bottles is one thing, but sterilizers that dry the bottles afterward can save you a lot of time in the long run.

  3. Size

    If you have limited kitchen counter space or wish to sterilize a lot of bottles at one time, for example, you’ll need to consider how big or small your sterilizer should be.

  4. Ease of use

    Most sterilizers are easy to use, but you’ll want to check this feature out before you make a final decision.


Choosing between a steam sterilizer or a UV sterilizer isn’t that difficult once you know which features are most important to you. Although steam sterilizers tend to be a little less expensive than UV sterilizers, UV sterilizers usually have the capability to sterilize many more items. Both come in a variety of price ranges and with many different features, so it’s up to you to decide which feature is most important to you.
