How Do I Choose the Best Bottle Sterilizer?

While the bestselling book, Dirt is Good: The Advantage of Germs for Your Child’s Developing Immune System, urges parents to introduce their children infectious germs to strengthen their immune systems, this technique should not be incorporated into your child’s daily life until they are at least six months old. That’s where a bottle sterilizer comes in. A bottle sterilizer can prevent harmful bacteria from infecting your baby during feeding time.

While there are other methods of sterilizing bottles, such as boiling water, they aren’t as effective. Hot water can wear down the bottles and make them unsuitable for use after a very short time. Alternatively, steaming and microwaving are efficient and harmless techniques that will protect your little one from catching an illness or bacterial infection such as gastroenteritis.

With a good bottle sterilizer, you’re not only assured of your child’s improved health and hygiene. You also have more time to bond with your child. Using a sterilizer means it only takes a few minutes to have the bottles ready. It’s even faster and easier if you have a bottle warmer, too. Most sterilizers today are versatile and can sterilize everything, including utensils, pacifiers, and plastic toys.

In this guide, we’ll walk you through everything you need know about these vital tools, including the different types, their differences, and how to pick one that will serve you best. For instance, if you have twins you’ll need a sterilizer that can hold as many bottles as possible. On the other hand, if you’re looking for a travel-friendly option then you’ll need a compact unit that can fit easily in a tote bag. Now that we’ve introduced ourselves, let’s talk about how much a good bottle sterilizer is likely to cost, as well as what features to consider when making your purchase.
A good bottle sterilizer will cost you between $20 and $250, depending on what it can do. For instance, a sterilizer will cost more if it keeps bottles and pacifiers sterile for up to 24 hours. A bottle sterilizer’s price can also vary based on its capacity, portability, and brand. Some sterilizers can hold up to eight pieces of pumps and bottles at once while others can even hold feeding dishes. On the lower end you can find cheap bottle sterilizers, but we haven’t featured any because they are often unreliable and made from flimsy materials.
How do you pick a sterilizer that will meet or exceed your expectations? Simple answer: pick one with the right features. For example, if you want a travel-friendly unit that is equally useful at home, a compact unit that employs multiple methods of sterilization is the best for you.

Here is a list of the vital features to consider when buying a bottle sterilizer:
  • Sterilization method
  • Capacity and what it can sterilize
  • Material and ease of portability
  • Size of your microwave
  • Time taken to sterilize
  • Auto shut-off and drying functionality
  • How long the bottles stay sterilized
  • Warranty
With these features in mind, let’s go a step further and discuss how these features affect design and, ultimately, the performance of a bottle sterilizer.
Construction and Design
Because there is no room for even the mildest germs, the best sterilizer should kill at least 99%, if not 100%, of germs and bacteria. As a sign of quality assurance, some models undergo independent laboratory tests or come with special warranties. When it comes to construction, consider the sterilization method, capacity, and material. Steam sterilizers are the are the most popular type of bottle sterilizer. They are usually either electric or microwavable, but some sterilizers can run on UV batteries.

Most electric sterilizers take less than ten minutes to sterilize up to eight bottles. Some advanced models can also dry and deodorize the bottles. Others can keep bottles sterilized for up to 24 hours with the lid closed. These sterilizers’ only downside is that they are bigger and more expensive. Other features that you’ll find in electric sterilizers include the auto-shutoff feature when a sterilization cycle is over and a descaling mode.

Microwavable bottle sterilizers differ in size and capacity, and they lack advanced features like drying and deodorizing. However, they are cheaper, equally powerful, and take less than five minutes to sterilize. Most microwavable sterilizers can fit up to four bottles. Remember to check the size of your microwave to ensure the sterilizer will fit.

UV battery powered sterilizers are loved for being travel-friendly and for their small size; however, they can only sterilize a single bottle at a time and take longer to sterilize. For any sterilizer that uses water, use distilled water, if possible, to avoid build-up of scales or go for a unit with a descaling mode feature.

After deciding on a sterilization method, choose your preferred capacity. While UV sterilizers always have a low capacity, electric sterilizers can hold up to eight bottles at once. Some models can also sterilize breast pumps, pacifiers, and other feeding equipment. Some sterilizers can only sterilize a specific brand or size of bottles. For best results, go for a BPA free unit that can sterilize standard baby bottles, wide neck-necked bottles, anti-colic bottles, and unusually shaped bottles.
Performance and Ease of Use
The performance of a bottle sterilizer will depend on your preferences. Remember to keep capacity in mind and choose a sterilizer that is compatible with your baby bottles’ size and brand. Sometimes babies reject certain bottles and favor others, so it may be smart to go for a versatile sterilizer that allows you to adjust accordingly. If you aren’t breastfeeding, you’ll probably require more bottles so a sterilizer with a larger capacity is important.

If you’re not on a tight budget, go for a large unit that can hold as many bottles and accessories as possible and keep them sterilized for up to 24 hours. This makes sterilization a once-a-day activity. For further ease of use, look for a sterilizer with an on-indicator light and an auto-shutoff feature. If you go for a microwavable sterilizer, ensure it can fit a wide range of microwaves
