How Do Microwave Bottle Sterilisers Work?
Microwave sterilisers use steam heat to eliminate harmful bacteria from bottles, teats and feeding accessories. You add a small amount of water to the base, load up your clean bottles and microwave for 2-8 minutes depending on your microwave's wattage. The steam reaches temperatures high enough to kill 99.9% of bacteria without chemicals.
What Key Features to Consider When Choosing a Microwave Steriliser
Here are just a few of the key things to think of when buying:
Capacity: Most hold 4-6 bottles per cycle (if you have a larger family you might want 6-bottle models)
Microwave compatibility: Check the dimensions fit your microwave (most fit standard 700-1000W models)
Sterilisation time: Ranges from 2-8 minutes depending on wattage
Material safety: All our sterilisers use BPA-free plastic that won't leach chemicals
Ease of cleaning: Smooth interiors without hard-to-reach corners clean faster
Included accessories: Tongs for safe handling and bottle racks for organisation.
What are the Different Types of Microwave Sterilisers
We stock three main types to suit different needs:
Compact Sterilisers
