Baby bottle sterilizers can be divided into three types according to their disinfection methods: high-temperature steam disinfection, mercury lamp ultraviolet disinfection, and LED ultraviolet disinfection.
High-temperature steam disinfection: This method primarily involves adding water to a base, and using the resulting steam, which reaches a temperature of 120℃, to sterilize the baby bottles, which is also the working principle of the bottle steamer. However, this method can only be used for items with high heat resistance, such as baby bottles, toys, dishes, and cups, and is not suitable for sterilizing items such as masks and keys.
Mercury lamp ultraviolet disinfection: This method uses ultraviolet radiation from a mercury lamp to disinfect baby bottles. The mercury lamp is similar to the ones used in classrooms in the 80s and 90s. This technology has been developed in China for many years and is mature, but it has a slow preheating time and produces mercury vapor.
LED ultraviolet disinfection: This is a relatively new ultraviolet disinfection technology that has emerged in the past few years. This technology uses small bulbs that are the size of fingernails. It has a fast preheating speed, is green and safe, and may replace mercury lamp disinfection in the future.
Key points for selecting a sterilizer based on disinfection methods:
For those with a general budget who only want to use it to sterilize baby bottles, a sterilizer that uses high-temperature steam disinfection is recommended.
For those with a larger budget who wish to disinfect a wider variety of items, an LED UV milk bottle sterilizer is recommended.
Mercury lamp ultraviolet disinfection is not recommended because of the risk of mercury poisoning due to the risk of breakage, and the production of ozone during the disinfection process, which can contaminate the air in the home and is not friendly to babies.
Currently, baby bottle sterilizers on the market range in capacity from five to over ten baby bottles. Here is a reminder for new parents when selecting a sterilizer: do not choose a sterilizer based on just one or two baby bottles, as space is also needed for baby plates, food bowls, and various toys.
Key points for selecting a sterilizer based on capacity:
If you have only one baby, a sterilizer with nine baby bottle slots should be enough, and there will also be room for food bowls, plates, and toys. If you plan on having a second baby in the next few years, it is recommended to choose a larger sterilizer, as each sterilizer is guaranteed for five years. If the capacity of the sterilizer cannot meet actual needs in the future, it may not be cost-effective to buy a new one.
If you have twins, choose a double bottle warmer and sterilizer with the largest capacity available.
All baby bottle sterilizers use the same drying method: by using a built-in heating system to heat the air inside the sterilizer, which evaporates the water from the baby bottles and discharges it from the sterilizer, achieving the effect of drying.
There are two main types of heating systems: one uses a common heating wire, and the other is a more advanced PTC heating system.
Heating wire heating principle:
The heating speed of the heating wire is not constant, and its temperature will become higher with prolonged use. This can cause the drying temperature to exceed the recommended level, making the baby bottles more likely to turn yellow. Over time, the lifespan of the baby bottles will be accelerated.
PTC heating system heating principle:
The lifespan of the PTC heater is long, up to 10 years or more, and it is safe. The heating element does not turn red when heating. Additionally, the PTC heating piece uses internal temperature control, which never exceeds the set temperature. This can effectively protect the baby bottles and prevent them from turning yellow.
