Microwave bottle sterilisers are fast, chemical-free sterilisers that fit in your microwave (because keeping bottles germ-free shouldn't require half your kitchen bench).
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
Perfect for small kitchens or travel. These hold 2-4 bottles and fit easily in most microwaves and cupboards. Lightweight enough to pack in your hospital bag or take on holidays.
Large Capacity Sterilisers
Ideal for families with multiples or those who prefer batch sterilising. Hold 5-6 bottles plus accessories, reducing how often you need to run cycles throughout the day.
