Capacity: Approximately six bottles | Materials: BPA-free plastics and metal electrical components | Included: Steriliser and teat tongs – larger sets are also available to buy Good for parents who Cold water sterilisers involve filling a container with water and adding sterilisation tablets or fluid to make a sterilisation solution. The active ingredient is sodium hypochlorite, which is a mild bleach that has been through a purification process to make it stable and non-toxic. It’s perfectly safe to use, but does smell vaguely of swimming pool. Finally, she looked at whether the steriliser represented good value for money considering the features it provided for a wide customer base, noting whether or not she’d buy another if the sample model broke. We spend hours researching, speaking to parents, analysing data and listening to experts before we test out the products on our shortlist.

I have the Nuby UV one and I love it. I wash the bottles and let them air dry and then put them in there dry for three minutes and it's done! If you're formula feeding Nuby had a sale on their UV steriliser and Rapidcool (can make milk to NHS recommendations and they be cool in 3/4 minutes) bundle."

We filled baby bottles of various sizes and shapes with milk and turned on the warmers, noting how long it took to prepare the bottle warmer and sterilizers for use. Parenting editors set a timer on their phones to determine the timing of the warming process. After the warming cycles, we carefully removed bottles, swirling milk to ensure warming was evenly distributed. Next, we tested the temperature of the milk by lightly pouring it on the inside of the wrist. Moreover, we used a liquid thermometer to measure the temperature of the milk. Lastly, we unplugged each unit, waited for it to cool down, and cleaned them according to the manufacturer’s recommendations. Electric sterilisers attract limescale on their heating plate over time so will need regularly descaling (manufacturers will specify a frequency, but it’s usually once or twice a month). To reduce limescale build-up, pour out the water after every use and wipe down with a soft damp cloth. It takes one touch of a button to start a cycle and, if you have any accompanying Tommee Tippee bottles, each bottle is clearly marked to show how much water to add to the steriliser – a thoughtful touch that our tester really appreciated. There are four main sterilisation units on the market: cold water sterilisers, microwave sterilisers, electric sterilisers and travel sterilisers. They all have their own pros and cons. 1. Cold water steriliser

All bottle sterilizers on our list are compatible with most bottle brands, shapes, and sizes. For example, you don’t have to only use Dr. Brown’s bottles with the Dr. Brown’s Deluxe Bottle Warmer and Sterilizer—this unit is compatible with all of the company’s bottles and most other brands.Milton do a travel steriliser that fits 1 bottle in. In theory any clean plastic container with a lid will do, but the travel sterilisers have the lines on so you put the correct amount of water in (as do the normal Milton sterilisers)." Recommended by Mumsnet user confused123456 Our verdict Capacity: Six bottles, plus breast pump parts | Materials: Plastic | Included: Container and weighted grid Good for parents who To select the best bottle sterilizers, we spoke with Tomomi Hayashi, MD, a California-based board-certified pediatrician, and Arunima Agarwal, MD, a New York-based board-certified pediatrician to find out what to look for in a bottle sterilizer and the benefits of bottle sterilization. We also reviewed guidance from the AAP, the CDC, and Texas Children's Hospital, on why it’s important to sterilize baby bottles. Moreover, we also put 20 bottle warmers, including some bottle warmer and sterilizer combos, through multiple tests at the Verywell Testing Lab in New York City with the help of Ebony Barrett, PNP. We appreciate how easy it is to use the sterilizing function thanks to clear manual instructions (push one button after adding some water, and you’re good to go). On the other hand, the warming process was slightly confusing, and difficult to tell if it was working or not. Depending on the volume of the milk, the timer shows the number of minutes necessary to warm the milk, but the process is not intuitive.
