Finding the Best Baby Bottle Sterilizer or Sterilizer Dryer

Babies have very weak immune systems, especially right after birth, so sterilizing all baby products that they put in their mouth like bottles or that are used in feeding like pump parts is critical to preventing bacterial infections. If you are wondering how to sterilize bottles, you should consider a baby bottle sterilizer appliance.

What is a Bottle Sterilizer Used For?

A bottle sterilizer is a machine used to kill germs and bacteria that remain on the surface of a bottle even after washing. The best bottle sanitizers will sterilize breast pump parts, baby bottles, pacifiers and teething toys. Wondering how to find the best baby bottle sterilizer for you? Keep reading our guide to help you choose.

Choosing a Sterilizing Method

Since there are an array of sterilizing approaches and products, this blog is designed to help you easily find the right sterilizing approach, or best sterilizer for your needs so you can kill 99.9% of germs and keep your baby healthy!  

Step 1: Figure out your sterilizing approach. Determine if you want to sterilize only OR if you want to sterilize and dry together. Some parents choose a sterilizer only option because you can use products in your house like a pot, stove or microwave, you already have a drying rack and it's usually less expensive. Others choose to automatically sterilize & dry because it saves a lot of time and effort to combine these two steps and products stay sterile throughout the drying process, minimizing germ contamination. 

Step 2: Once you decide on your bottle sterilizing approach, then you can determine which specific type of product is the best bottle sterilizer for you. 

Sterilize Only: If you choose this approach, there are several options to consider:

• Boiling: You can boil a pot of water to sterilize bottles on the stove. As long as they stay under the boiling water for at least 5 minutes, they will be sterilized. One downside is the time and effort sterilizing baby bottles on stove takes – you have to babysit the bottles and make sure they stay under the boiling water because if they float and the boiling water doesn’t touch the bottles, they won't get sterilized.
• Microwave Steam Bags: You can also purchase microwave steam bags and place products inside along with some water. Downsides to this approach are these bags typically have limited capacity, they can only be used 20 times before wearing out and steam rushes out when you open the bag after microwaving which can burn your hands.
• Sterilization machine for home: You can also buy a electric appliance that automatically sterilizes your bottles and pump parts with natural steam. Downsides to this approach are the cost vs the other methods.

Sterilize & Dry: If you choose this approach, there are two options to consider, both of which include automatic drying which saves time & effort and keeps your baby products sterile throughout the entire process:

Steam Sterilizer-Dryers: You can buy an electric bottle sterilizer that uses natural steam to kill 99.9% of germs, then automatically dries bottles, pump parts and other accessories with hot air. These products make the entire process super easy. Downsides to this approach are these appliances cost more than a sterilizer only.

UV Sterilizer Dryers: You can also buy an appliance that uses UV light to kill 99.9% of germs, then automatically dries.

Is Steam or UV Sterilizer Better?

There are a few downsides to UV bottle sterilizers. These appliances are usually much more expensive than a steam sterilizer-dryer, plus they only kill germs if the light directly shines on the product surface. Most UV sterilizer dryers rely on mirrors to bounce the light around inside the appliance, so there’s no guarantee it will directly shine on the entire surface area of your bottles or pump parts.
