1. Overview of brand and pricing
Fatz or Fatzbaby is a renowned South Korean brand of bottle sterilizers known for its diverse models and affordable prices, catering to the majority of Vietnamese mothers. The Fatz bottle sterilizer brand offers a wide range of UV sterilizers, dryers, and milk warmers, as well as steam sterilizers. In addition, there are various single, double, and multi-functional electronic models to meet the essential needs of breastfeeding mothers. Prices range from 420,000 VND to 3,530,000 VND per product depending on the model.
On the other hand, Chilux is an international brand of bottle sterilizers sold in many countries, including Vietnam. Specifically in the Vietnamese market, the Chilux bottle sterilizer entered later than Fatz, so its coverage is not as extensive and it is less known to breastfeeding mothers. Additionally, Chilux offers fewer options in terms of models, with only the Chilux C1 multi-functional sterilizer available in white and pink. Prices range from 1,680,000 VND to 2,584,000 VND per product depending on the seller.
When comparing sterilizers with similar capacities and functions between Fatz and the Chilux C1 model, mothers will notice that Fatz still provides diverse options and is more cost-effective.

2. Comparing the materials and design of Fatz and Chilux bottle sterilizers
Long-standing brands and affordability are not necessarily the top criteria driving modern breastfeeding mothers' purchasing decisions in today's era. For many mothers who prioritize safety and aesthetics, material and design criteria are the factors for comparison.
2.1. Material
Both Fatz bottle sterilizer and Chilux utilize similar types of materials, including:
- The machine shell is made from premium PP plastic with a certain degree of strength and heat resistance to prevent burns and enhance product durability during long-term use. This plastic material does not contain harmful BPA, making it safe for users' health.
- The heating flask is made from Borosilicate glass.
- The heating base is made of SUS316 stainless steel. This is a superior material to SUS304 stainless steel due to its higher molybdenum content, thereby providing better corrosion resistance, fast heating performance, and good heat resistance.
2.2. Design
When viewed from the outside, the multi-functional sterilizers from Fatz and Chilux appear quite similar. These machines are divided into two separate areas and can operate simultaneously. This design allows breastfeeding mothers to multitask efficiently, such as sterilizing, boiling water, warming milk, or baby food, saving time. However, the differences are also noticeable:
- Regarding size: While the Chilux bottle sterilizer boasts a compact design, the Fatz sterilizer is slightly larger than Chilux.
- Regarding control panel: In the Chilux bottle sterilizer, the control panel and display screen are designed directly under the machine's base, with instructions written in Vietnamese for easy understanding and convenient operation. On the other hand, in the Fatz sterilizer, the control panel is designed in various areas, depending on the model, but overall, it is clearly divided into two sections corresponding to the left and right sides. The functions are depicted with clear images, although they may not include Vietnamese instructions. However, after reading through the instructions and using it a few times, it becomes intuitive. Later on, simply looking at the symbols on the control panel makes it easy to use.

3. Comparing power and capacity
When choosing a bottle sterilizer, mothers often pay close attention to the power to determine how quickly water can be heated, how long it takes to dry the bottles, and how many wide-neck bottles it can hold to accommodate additional items such as pacifiers, nipple shields, spoons, bowls, and baby food plates. For Fatz and Chilux:
3.1. Regarding power
Công suất | Máy tiệt trùng Fatz | Máy tiệt trùng Chilux |
Công suất tiệt trùng | 500W | 700W |
Công suất sấy khô | 115W | 180W |
Công suất nấu chậm | 500W | – |
Công suất đun sôi | 800W | 700W |
3.2. Regarding capacity
In the Chilux bottle sterilizer, it can hold up to 5 wide-neck bottles, and the boiling flask can hold about 1.3 liters of chlorine-free water. Meanwhile, in the Fatz sterilizer, the number of bottles that can be accommodated in the sterilization chamber is about 4-6 wide-neck bottles depending on the model, and it can also hold up to 12 bottles depending on the capacity. The boiling flask can hold about 1.2 liters of chlorine-free water.

4. Features of Fatz and Chilux bottle sterilizers
Not only boasting beautiful designs, the Fatz bottle sterilizer is also equipped with many outstanding features such as:
- A variety of modes and optional functions including: Sterilization, drying, yogurt making, slow cooking porridge, warming milk and food.
- Allowing customization or scheduling according to preferences.
- Automatically turning off when the temperature is too high or when there is no water in the flask.
- Not only boiling chlorine in 5 minutes, but also keeping the boiled water warm at a temperature below 70 degrees Celsius for 24 hours continuously.
- The temperature range can be adjusted to within 1 degree Celsius, ranging from 35 degrees Celsius to 95 degrees Celsius.
- It has a function to remember the last set operation for reheating milk to shorten the time for subsequent uses.
Compared to Fatz, the Chilux bottle sterilizer is also equipped with similar functions but operates more smoothly (20dB), with a difference in the time it keeps warm at temperatures of 40 degrees Celsius to 45 degrees Celsius for 48 hours.
Overall, both Chilux bottle sterilizer and Fatz have their own strengths and weaknesses, but mothers can consider:
- If you're looking for diversity in models, features, aesthetic design, ease of use, affordability, and good quality, opt for the Fatz sterilizing machine.
- Choose the Chilux milk bottle sterilizer if smooth operation and a slightly faster sterilizing process are preferred, despite its higher price tag.
