What is a bottle sterilizer?

In the maternity field, when we talk about sterilizers, we usually refer to sterilizers mainly for teats, bottles and pacifiers. Their function is to destroy or eliminate any germ or bacteria present in these utensils through physical, chemical or gaseous procedures.

We all know the importance of hygiene and cleanliness of the utensils we use to feed our baby, especially in the first 6 months of life.

This is because babies are born without a fully developed immune system, so they are more likely to be attacked by germs or bacteria.

For example, one of the most common infections is gastroenteritis. Today, this is one of the most common reasons for paediatric consultation and hospitalization in Europe.

To avoid infections like this or at least reduce the risk, it is important to sterilize your baby’s bottles, teats and soothers because they are in direct contact with his or her mouth.

Of course, sterilization is necessary, but that doesn’t necessarily mean we need a sterilizer.

In the case of bottles, teats and soothers, it is usually sufficient to sterilize them once before the first use. To do this, we simply have to boil them in water for about 10 minutes. After that, it is enough to wash them thoroughly with water and neutral soap every time we use them.

Doing that is enough, but if you are going to feel more comfortable and safe sterilizing bottles, pacifiers and nipples every time you use them, then it is worth buying a sterilizer.

It’s true that you could do it “manually”, as I explained earlier, but it will take you a long time each time and it won’t make up for it.

However, keep in mind that if you are going to choose to breastfeed, you will be using it very little. In that case, you will have to assess whether it really pays off to buy it.

However, if you are doing a mixed feeding (breastfeeding – formula) or just formula, you will use it much more and you will be able to get the most out of your investment.

Where to Buy a Sterilizer?


There are many places to buy a sterilizer, from the “neighborhood” store specializing in maternity to the department store or online stores. The advantage of buying it online is that it is more convenient and also allows you to easily compare brands and prices. We also tend to find better prices than in physical stores.

If, in the end, you choose to search on the Internet, don’t just look at the price. It is important to take into account the return policies of each online store. Of course, they will all allow you to return your sterilizer if it is defective, but what if it simply doesn’t fit what you expected? Will you be able to return it without any problem and without cost?

With Amazon, yes, for sure. Have I ever had to return a product and I’ve done it without having to explain myself, quickly and simply and at no cost?

The range of sterilizers offered by Amazon is wide enough for you to find one that fits you. Moreover, you will receive it in a matter of hours or days (4-5 days maximum depending on the type of shipment you choose).

And what about their prices? They are always lower than those of physical stores, but also, from time to time, they put out offers on baby products with savings of up to 40% compared to “traditional” stores. To make it easy for you, in this page I will leave you the best updated offers that you will find.

Types of Sterilizers

There are different types of sterilizers depending on the disinfection system they use:

Cold sterilizer

It uses disinfectant tablets or liquid that we introduce in a container with water that covers the objects that we want to disinfect. It is comfortable because it does not need heat. Instead, it takes about 30 minutes to perform the disinfection.

Microwave sterilizer

It is one of the most used nowadays, mainly because of its ease of use. They have a container suitable for the microwave where we put the utensils to be disinfected and we cover them with water. In less than 15 minutes it will be ready.

Steam sterilizer

It is an electric appliance composed of several “plants”. On the “first floor” we have a plate that generates heat. In the “second floor” is where we put about 200 ml of water that, by effect of the heat produced by the plate of the “first floor”, will be transformed into steam of water that will be the person in charge to sterilize the utensils that we have placed in the “second floor” and following.

It takes about 10 minutes to complete the process, it is clean and can sterilize quite a few utensils at a time. On the other hand, it is the most expensive and the one that takes up the most space. You have to be careful where you place it because it releases water vapor and its casing gets quite hot. By placing it in a suitable place and taking the appropriate measures every time we handle it, we will not have to worry about it.

How to choose the sterilizer that suits you best?


When choosing the most suitable sterilizer for you, I suggest you take these 4 factors into account:

Disinfection system used

As I mentioned earlier, there are 3 types of sterilizers: cold, microwave or steam.

The most commonly used today are microwave and steam sterilizers. Unlike the “cold” one that uses chemicals to disinfect, the other two use water, so they are more “natural”. In addition, you will not have to rinse the utensils once they have been disinfected and there will be no trace of taste or smell in them.

Also, in the long run they will be cheaper, since the only ingredient they use is water. However, cold sterilizers require a chemical product (tablets or liquid) that you will have to buy as you use them.

Considering all this, I prefer the microwave or steam sterilizer to the “cold” one.

Disinfection time

It is clear that spending 10 minutes a day on sterilization is not the same as spending 30. If you have enough time to do it, this will not be a major factor in deciding on one or the other sterilizer.

However, if you are one of those who spends all day running, you will appreciate the time it takes to sterilize the different utensils because, at certain times, 5-10 minutes more can give you life.

Size and Capacity

The size of the sterilizer is important, especially if you have little space at home. As I mentioned before, with steam sterilizers you have to take a series of precautions that are not necessary in microwave sterilizers. This undoubtedly affects the place where we put it when using it.

That’s why it’s important to make sure that we have a proper place to use the steam sterilizer. If you don’t have that space, opt for a microwave sterilizer.

With regard to the microwave sterilizer, we only have to make sure that it is suitable for our microwave.

Another aspect to take into account is the capacity. That is, how many bottles and teats it can disinfect at the same time.

I used to say that time is a factor to take into account, but it is no use having the fastest sterilizer on the market if it only sterilizes one bottle at a time.

To find out what capacity you need, check how many bottles and teats (and which type: standard or wide-mouth) you use on average per day.

Depending on the number of utensils and how many times you want to sterilize per day (the more times, the longer you need), you will need more or less capacity.

It is important to note that most sterilizers are designed to disinfect bottles and nipples, but not other types of utensils such as breast pumps, pacifiers, grasping tongs, plates, etc. However, some do have an adjustable size so you can disinfect more than just bottles and nipples.

Therefore, depending on what you want to disinfect, you will have to choose one type of sterilizer or another

Available accessories

It is not a relevant factor, but they always come in handy. Some sterilizers include accessories such as grasping forceps, pacifiers or bottles. Others, however, come only with the sterilizer.

Which is the best Sterilizer?

The million dollar question. Well … it depends on your needs and the resources you have, especially space. For your choice to be right, it is important that you take into account the 4 factors I mentioned before.

Anyway, to make it easier for you to compare, I have made a comparative table (I update it frequently) with my selection of what I consider the best sterilizers.

There is no “official” study on the best sterilizers. To make the list, I have based it on my own experience as well as that of other mothers. I believe that it is a more than valid criterion and that it can help you a lot when deciding on one.

Which one would I buy?

From my own experience and taking into account the quality/price, this:

Philips Avent Microwave Steam Sterilizer for Baby Bottles

By operating at a higher temperature than the dishwasher, the Philips Avent Microwave Steam Sterilizer kills 99.9% of harmful germs in just 2 minutes.
