Best Bottle Sterilizers That Will Help Keep Those Germs Away

Almost all parents have plenty of worries and fears during the first few years of a baby’s life. Some worry about sickness, while other parents fear exposing their little ones to germs. However, it’s hard to eliminate germs from everything your baby touches or eats. And, this is where a bottle sterilizer comes in handy.

The CDC– Center for Disease Control and Prevention recommend sterilizing baby bottles and other accessories, at least once a day for babies with a weekend immunity, born prematurely or are younger than three months. With a sterilizer, you can conveniently sterilize your baby’s bottles without having to boil water every time. You get to kill germ without doing any tedious work. That’s a win-win for any parent.

Buyers Guide

  1. Do I need a sterilizer?

    Answer: Yes, you do need a sterilizer. A sterilizer eliminates the need to always boil water every time you want to disinfect your baby’s bottle. This, in turn, helps make your work easier.

  2. Are there different bottle sterilizers?

    Answer: There are three different bottle sterilizers: An electric steam, UV light sterilizer, and a microwave steam sterilizer. An electric steam sterilizer harnesses electric steam to kill germs. However, it’s more effective compared to boiling water, as it can reach higher temperatures. The UV light sterilizer uses ultraviolet light disinfection to kill germs and bacteria. It does so by altering the bacteria chromosomes and prevents cell division. The microwave steam sterilizer also uses steam to kill germs. But, unlike the electric steam device, it’s more affordable.

  3. What factors should I consider when purchasing a bottle sterilizer?

    Answer: First, consider the sterilizing method that best suits you. Second, consider the length of the cycle. Some sterilizers work in under two minutes, while some take up to 20 minutes. The drying feature is also another significant factor to consider. If you’re a busy parent, you can choose to purchase a sterilizer with a dry feature. Lastly, look at the size of the sterilizer. Most can hold between 4 to 6 bottles, and may also have extra room for pacifiers and pump parts.
