Philips AVENT 4-in-1 Electric Steam Sterilizer Review

Philips Avent 4-in-1

Phillips Avent is primarily known for their extensive baby bottle line, but did you know they also make the best bottle sterilizers? They offer a wide range of sizes and types ranging from microwaves sterilizers to countertop steam-powered models. Their latest model, the 4-in-1, offers a larger capacity compared to competing models, with the ability to hold up to six bottles per sterilizing cycle. Other models in this price bracket can only hold two to three bottles, however, many of those models also offer a variety of functions, such as bottle warming, while this model is strictly a bottle sterilizer.

Our Verdict: If you’re looking for a large dedicated bottle sterilizer, then this model by Phillips Avent is the perfect option. It has a short sterilizing cycle of just six minutes, so you can swap out bottles and do several batches in under twenty minutes. It can hold up to six bottles per cycle and accepts bottles of all shapes and sizes. You can also use it to sterilize bottle accessories, pacifiers, teething rings, and breast pump accessories. While it doesn’t come with any extra features such as drying or a built-in bottle warmer, the fact that it has a larger capacity compared to other models in this price range is a big selling point, especially for parents with twins.

Overview and Features

The manufacturer claims that its four-in-one bottle sterilizer can kill 99.9% of harmful bacteria. This is an impressive claim and one that gives every parent a reason to buy. While not all parents will sterilize their infant’s bottles after a feeding, it’s actually crucial if you have a baby that has a weakened immune system, your baby was born prematurely, or if they’ve just gotten over a serious illness such as walking pneumonia, or the flu. Many medical professionals recommend using a bottle sterilizer regularly until babies reach at least three to six months of age. By this time, their delicate immune system will have had more time to develop and strengthen.

Our Rating: (4.5/5)

Philips Avent 4-in-1

  • Can hold up to six bottles
  • Kills 99.9% of germs
  • Easy to clean and maintain
  • Reasonably priced
  • Short six-minute sterilizing cycle
  • Two-year warranty

Sterile Conditions

This model uses electricity and steam to sterilize baby bottles, nipples, bottle rings, caps, pacifiers, teething rings, and small toys. Basically, you can put anything that’s small enough inside the sterilizing compartment. This is especially important to breastfeeding mothers in need of a way to sterilize their breast pump accessories.

Bottle Design

Some bottle sterilizers will only accept standard-sized baby bottles. However, this appliance is different. It can easily hold angled, narrow, or wide-mouth bottles. In fact, it can hold up to six eleven ounce bottles, with a little room to spare for bottle accessories.

Dishwasher Basket

This model comes with an integrated dishwasher basket, which you can use to wash the bottles and all accessories in, prior to placing them in the sterilizer. This will help to keep all of the bottle’s accessories together when placed in the dishwasher.

Sterilizing Cycle

As I briefly touched on earlier, this machine can kill up to 99.9% of harmful germs and bacteria during the intense steam sterilization process. To use, add water to the machine’s base, load the rack, plug in the machine, hit the start button, and your bottles will be clean and sterile in as little as six minutes. This machine operates at a much higher temperature than a standard dishwasher, using electricity in order to generate the steam. Once the cycle is complete, the machine will automatically shut off.

Once the bottles are removed from the sterilizer, they will remain sterile for a period of twenty-four hours with the lid placed over the nipple.


Philips Avent 4-in-1

This model comes with a two-year full manufacturer warranty. Most models in this price range don’t offer a warranty at all, so one of this length is a pleasant surprise that all parents will appreciate.


New parents have a lot to learn, including how to sterilize bottles and which method is the most effective. Most doctors will tell you that this steam electric countertop model is the safest, most effective way to go. So, how often should you use this sterilizer? Some parents may only use it to sterilize brand new bottles. Others will use it on bottles that their infants use at daycare or when they’re out and about. Parents with preemies will use a bottle sterilizer for each and every bottle since preemies have a weak immune system. Many parents think that using the dishwasher is enough to kill harmful germs and bacteria, but it’s not.

Using a sterilizer is the only way to kill 99.9% of germs. How often you use this model will be entirely up to you, but if you want to prevent your little one from relapsing after an illness, they go to daycare, they have a compromised immune system, then using a sterilizer regularly can help to ensure they remain healthy and happy. To learn more about sterilizing make sure you read my in-depth sterilizing guide, which includes different sterilizing methods you can try and why a countertop steam model is the best option.

Phillips Avent Versus Dr. Brown’s Deluxe Bottle Sterilizer

Dr. Brown’s is one of Phillips Avent’s biggest competitors. Both manufacturers specialize in their extensive bottle product lines that are specially designed to prevent gas and minimize the signs and symptoms of colic. The Phillips model is by far the most versatile in terms of which types of bottles you can sterilize. The Dr. Brown’s model states that it should only be used to sterilize Dr. Brown’s bottles, although the interior of the sterilizer looks as though it can handle most standard-sized eleven ounce bottles.

Both models are dedicated sterilizers, so they don’t come with any special extra features such as a bottle warmer or baby food warmer. However, the model by Dr. Brown’s comes equipped with a separate sterilizing tray which parents can use to sterilize nipples, teething rings, bottle accessories, and pacifiers. Additionally, this competing model is available at almost twice the price. So, if you’re simply looking for an affordable, easy to use, efficient bottle sterilizer, I’d stick with this Phillip’s Avent model. However, if you’re a dedicated Dr. Brown’s bottle user, then purchasing their sterilizer makes sense.

Conclusion and Rating

Our Rating: (4.5/5)

Philips Avent 4-in-1Parents in search of a basic sterilizer with a simple and quick sterilizing cycle will appreciate how fast and efficient this model is. It’s not flashy like some competing models and doesn’t come equipped with a large LCD display or any additional functions, however, for a dedicated sterilizer, it does its job well.

This machine by Phillips Avent functions strictly as a bottle sterilizer. It doesn’t offer any warming features, which may be a drawback for some parents, however, those who are looking for a dedicated bottle sterilizer with a larger than average capacity will love how versatile this model is. Unlike competing models, this machine can sterilize bottles of any shape and size, which is a huge plus. The inside rack is highly adjustable, so you can tweak it to fit any type of bottles, breast pump accessories, and any other baby items.  I gave this machine a rating of four and a half stars out of five.
