Microwave sterilisers use steam to kill up to 99.9% of harmful bacteria in 2-8 minutes
They're more compact and portable than electric sterilisers (ideal for travel)
Most models hold 4-6 bottles per cycle and fit standard microwaves
BPA-free materials and chemical-free sterilising keep baby's bottles clean.
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.
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.
We stock three main types to suit different needs:
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.
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.
Come with everything you need to start sterilising immediately. Think sterilising unit, tongs and sometimes bottles. Great for first-time parents setting up their bottle feeding essentials.
Microwave sterilisers offer practical advantages over other methods:
Faster than traditional boiling: 2-8 minutes vs 10-15 minutes on the stovetop
No chemicals required: Steam sterilisation means no tablets or solutions to buy
Energy-efficient vs electric sterilisers: Uses less power and takes up zero bench space
Portable and lightweight: Easy to pack for travel or hospital stays
