1. Best baby bottle sterilizer
A. Traditional Electric Steam Version
This is one of the top rated baby bottle sterilizers and it is not hard to see why.
Sleek and compact in size, the Philips AVENTS 3-in1 Sterilizer
kills 99.9% of germs through 6-minute intense steam sterilization. Using temperature higher than a dishwasher, it generates steam through electric to sterilize its contents.
Once sterilization is complete, the machine will shut off automatically for safety. If the lid remains unopened, the contents will remain sterilized for up to 24 hours.
Free from BPA and backed by a 2-year warranty, it also includes a pair of tongs for you to remove the sterilized contents safely and conveniently.
Do not be fooled by its size – it can fit up to 6 Philips AVENT 11-ounce bottles at its full capacity.
If you need to sterilize other items, do not worry, its adjustable rack allows you to clean different sizes of bottles, accessories and equipment. Such adjustable size also means it takes up less counter space.
One downside is that this steam sterilizer requires 10 minutes to cool down after one use which means you cannot sterilize your next batch of items straight away.
Another and most common ‘complaint’ about this sterilizer is that ‘rust’ will form at the base after several uses.
A big misunderstanding there - these ‘rust’, are generally caramelised milk residue due to the intense temperature, nothing a few vinegar-water couldn't clean-up.
Also, the Philips AVENT 3-in-1 Electric Steam Sterilizer does not dry bottle or other items so you will need to dry the contents on a drying rack after removing them from the sterilizer.
If you are looking for the best electric steam steriliser, this is it.
To get the best value, parents often buy the Philips AVENT Natural Newborn Baby Bottle Starter Set and the Philips AVENT Bottle Warmer combo together with this sterilizer and they will be good to go with the basic feeding and cleaning equipment.
The Dr Brown's Deluxe Bottle Sterilizer is another top rated electric steam steriliser that is loved by many.
A newly improved design which does not have an open bottom area anymore so that water cannot flow in for deposits to build up, it can sterilize up to 6 bottles at one time and it fits all Dr Brown’s baby bottles as well as most other bottle brands.
The new electronic controls have cycle indicators and will shut off automatically once sterilization is complete.
The removable tray allows you to position the bottles so that steam reaches each bottle directly thus ensuring a 100% sterilization.
You can place other small items such as teethers, pacifiers, bottle caps, breast pump equipment etc. on the tray and place it over the bottles for simultaneous sterilization as shown in the pictures above.
Like the Philips AVENT 3-in-1 Electric Steam Sterilizer, it does not dry the contents simultaneously so you would have to wipe them clean manually after removing them out.
Similarly, parents who buy the Dr Brown’s Deluxe Bottle Sterilizer also bought the Dr Brown’s Deluxe Bottle Warmer together to get the best value as well as the Dr Brown’s Bottle Brush which cleans baby bottles thoroughly, especially its own Dr Brown’s brand.
The biggest selling point of the Munchkin Steam Guard Electric Sterilizer is definitely its capacity. It is not surprising that this is the best baby bottle steriliser for parents expecting twins or more!
Fitting up to 9 bottles at one go, it starts the cleaning cycle with just a push of one button and it automatically shuts off upon completion of sterilization which takes 6 minutes.
The adjustable tray keeps bottles uptight and in place and it fits different sizes and brands of baby bottles.
You can place other items such as nipples, pacifiers, small toys, breast pump equipment on it as you like to sterilize them.
The heat resistant dome lid ensures you do not burn your hands while keeping hot steam trapped inside for thorough sterilization.
Parents love that it has heat-resistant tabs that close upwards to prevent accidental openings and that the one-way latch helps remind them to open the lid away from the body for safety purpose.
Also, the heat-resistant tongs provided can clip onto the adjustable tray for convenient sterilization as well.
Of course, one thing they cannot stop raving about is its large capacity that helps make their life easier and more convenient.
Nonetheless, its bigger capacity also means that the Munchkin Steam Guard Electric Sterilizer is bigger in size compare to other steam sterilizers and will therefore take up more counter space.
Also, it does not have dryer function as well so you will still need to dry them off these drying racks.
This steam sterilizer is often purchased by parents who are expecting twins or more as they have comparatively more bottles and items to sterilize at one go. It is also frequently bought together with the First Years Quick Serve Bottle Warmer by those who want a better deal.
This is a newer, improved version of the Tommee Tippie Electric Steam Sterilizer.
It comes in two colours – black and white and two versions – with handle and no handle, the latter being cheaper than the former. For convenience and safety purposes, we would recommend getting the one with handle.
This sterilizer takes only 5 minutes to sterilize its contents and is by far the fastest in the market, and despite only being able to hold 5 bottles at one time, its capacity is surprisingly large.
You can fit other feeding equipment such as nipples, pacifiers, breast pump equipment and small toys to sterilise together at one go as well. It is easy to operate which requires just a push of a button to start sterilizing and you are good to go after 5 minutes.
It is also easy to maintain as the base is smooth and does not have holes for water to drain, meaning it is easy to clean the base and you do not have to worry about deposits or mineral residues from forming.
You will be pleased to know that it also fits most bottle brands and sizes, apart from its own Tommee Tippie Closer to Nature bottles.
There is not much to fault this steam sterilizer, which is rated as one of the best steam steriliser, however, like most other brands, it does not have a dryer function.
If this is not a problem for you, then the Tommee Tippie Closer to Nature Electric Steam Sterilizer is a great product that is worth getting.
The First Years Power of Steam Electric Steam Sterilizer is another top bottle sterilizer well loved by many.
Bearing two separate adjustable layers of trays above the bottle racks, there is plenty of space for you to place smaller items such as nipples, pacifiers, equipment to sterilize alongside your baby bottles, which a maximum of 5 of any size and brand can fit.
Unlike most sterilizers that adopt a more rounded and shorter design, this electric steam sterilizer bears a tower-like design that stands tall amongst its other peers.
This allows steam to be directed into each bottle individually because steam is directed deep into the bottles for thorough sterilization with this unique design.
Another convenience that many parents love about the First Years Power is that the rack is totally removable to stand on its own as a drying rack.
This means you do not need to buy a separate drying rack to air-dry sterilized items like those of the above require. It’s like having your very own inbuilt drying rack that is completely detachable from the machine itself!
B. Electric Steam Sterilizer with Dryer Function
If you are concerned that all your sterilizing effort will be put to waste if you simply air dry them on a drying rack, why not consider the following list of best baby bottle steriliser and dryer?
The new Plus version of the Wabi Baby Electric Steam Sterilizer now comes with dryer function.
No longer do you need to air-dry your sterilized bottles and worry about it reversing the effect of sterilizing.
You can use both sterilizing and drying functions together, or independently.
Like most of its counterparts, the Wabi Baby takes 8-15 minutes, depending on the capacity of its content, to complete one sterilizing cycle.
The improved design memorizes the last setting under drying and auto mode so that you can just press on one button for your next use.
And oh, you can use it as a storage item too by keeping sterilized items for up to 12 hours if the lid remains closed.
It will automatically run drying for 10 minutes every 3 hours for 3 times to ensure its contents are kept dry and sterilized.
At its maximum capacity, you can fit up to 8 standard size bottles of any brand and the chamber style makes it easier for you to load all your items.
What’s better, is that an extra plate rack is provided to provide you the versatility of sterilizing different sized items of your infant needs.
The exclusive design of its bottle rack ensures that hot steam goes straight into the bottles to perform optimum sterilizing results.
Also, an air rotator is specially designed to increase air flow speed in the chamber to reduce drying time tremendously.
In fact, it claims that as long as you place all your items properly without blocking the airflow, the Wabi Baby will dry everything you fit inside.
Microbiologically tested and approved by independent lab, you do not have to worry about there being a burnt/chemical smell after each use as the Wabi Baby is made from FDA food grade approved material to ensure a toxic-free environment.
The downside of the Wabi Baby Electric Sterilizer is definitely its price but understandably so because you are getting a 3-in-1 sterilizing, drying and storage item.
Also, you will have to allow an hour for sterilization AND drying to be completed, so make sure you time your usage well or else you will find yourself not having enough bottles for baby to use.
NOTE: the Wabi Baby does not eliminate what other baby bottle sterilizer faces – mineral buildup maintenance.
You will need to clean the sterilizer regularly to clear buildups, but this is now made easy with a One Button Descaling, meaning you just have to press the descaling button to start the process.
This works best with the Wabi Baby Fast-Action Descaling Powder, which most parents buy also when they purchase the Wabi Baby Plus Version.
If you have a few extra bucks to spend, and are concern about air-drying reversing the effect of sterilization, the Wabi Baby is definitely your best bottle sterilizer and dryer.
Similar to the Wabi Baby, Baby Brezza has also come out with their own sterilizer with dryer function.
It also has an 8-minute sterilizing cycle with 30, 45 or 60 minutes of drying options for you to choose from.
Likewise, you can choose to sterilize only, dry only or both sterilize and dry options by using the easy-to-control panel.
The Baby Brezza Sterilizer Dryer can hold up to 6 baby bottles of any brand in its maximum capacity plus other smaller accessories.
It is better than the Wabi Baby in the sense that it keeps its contents sterilized longer (24 hours) if the lid remains closed.
Tthe reason we rate it second to the Wabi Baby is primarily its lesser capacity and flexibility.
The basket-like holder of the Wabi Baby allows you to chuck random smaller accessories onto it without worrying the lid will not close.
However, with the Baby Brezza, you will have to carefully stack up your items into the sterilizer or else you will not be able to close the lid.
Unless you are sterilizing bottles and nipples only, you may not be able to fit other accessories like small toys, breast pump equipment and the like which the Wabi Baby has no trouble fitting at all.
Also, if there is something hanging over the edge of the unit, you may find it difficult to close the lid.
If you are looking for a sterilizer with dryer that is purely for bottles and nipples, then you will love the Baby Brezza Sterilizer Dryer.
It lasts well unlike some which stop working after just a few months’ use, and the longer preservation of its sterilized content is definitely a plus point too.
No doubt that this is slightly pricier but it is still affordable. In fact, it is considered as a reasonably priced item amongst sterilizers that are equip with drying function.
The black sheep of the bunch, the UviCube is the first baby-focused sanitizing device in the US that utilizes ultraviolet (UV) light to sanitize its contents.
This means that it features a highly reflective inner chamber that maximizes the reach of UV light to kill bacteria on exposed surface of the contents inside.
Aside from sterilizing, it also dries and stores sterilized items until you need them.
All you need to do is place anything you wish to sterilize into the UviCube, including any moisture or heat-sensitive items like electronics, press a button and let the UviCube works its magic.
No longer is there the need to do any prior setup, such as filling the item with water like all the sterilisers reviewed above require for sterilizing purposes.
Because it does not use high temperature steam, you do not have to worry about risk burns or having to do any set up prior or clean up after.
UviCube is found to eliminate 99% of harmful bacteria and this is nationally recognized and verified by independent third party authorities.
The UviCube is generally bulkier than most sterilizers, however, it is still rather small and will sit well on any kitchen countertop without taking up much space.
Price is perhaps its only downside as the UviCube is the most expensive out of all.
But if you consider all the uses you can take out of it, the UviCube Uv Sterilizer, Sanitizer and Dryer is definitely a worthy investment for those who like to keep things clean and hygienic.
2. Other alternatives
A. Microwave Sterilizers
After fitting all that you need to sterilise and filling up the required water level, all you have to do is just close the lid and pop it into the microwave.

Other amazing features include the stay-cool safety grip, 1 year warranty and it also comes with 1 steam tray and 1 set of tongs. Extras like these are always a plus point.

B. Microwave Sterilizing Bags
If you want something even more convenient than the microwave steam sterilizer, you can consider the microwave sterilizing bags.
Fill the bag with small feeding items and water, pop it into the microwave and start on with the steam clean. Most bags are reusable (some as many as ten times!) so this is definitely a favourite alternative for many.
Many brands have come out with their own microwave sterilizing bags and they all function in the same way so we won’t review them one by one.
Bag size, quantity and price are the main factors to consider when buying your microwave sterilizing bags. Here is a list of the sterilizing bags available in the market for you to choose from:
Do note that these microwave sterilizing bags mainly used during travels and generally do not replace traditional sterilizers because it wouldn’t be economical to use them in a long term.
