NUK Micro Express Microwave Steriliser

The NUK Micro Express Microwave Steriliser uses steam to sterilise up to four baby bottles and their accessories in just four minutes, giving you a quick way to keep feeding equipment hygienically clean between feeds. It runs in your existing microwave with no chemicals involved, making it a practical daily option whether you're sterilising bottles, teats or breast pump parts.

With only three parts to assemble, it's simple to set up and just as easy to pack away. The transparent lid has a locking system for added safety, and an included pair of tongs lets you lift and remove hot bottles hygienically once the cycle is done. It's a straightforward choice if you want reliable sterilising built into a busy feeding routine.

How it works

• Steam sterilising: The unit uses steam generated in the microwave to sterilise bottles and accessories, so no chemicals are needed.
• Four-minute cycle: A full load of up to four bottles and their parts is sterilised in about four minutes, depending on your microwave.
• Locking transparent lid: The lid slides closed with markings to confirm it's properly shut, and locks for safer handling.
• Built-in holder: The holder positions bottles for drying after the cycle, and the included tongs let you remove hot items without touching them directly.

Fit and compatibility

The steriliser holds up to four 300 ml bottles plus their components (soothers are not included in the load). It's compatible with most standard and wide-neck bottle designs made from microwave-safe materials, so it can slot in alongside different feeding systems. Before buying, check your microwave has room: it needs a minimum interior height of 187 mm and a width and depth of 280 mm.

Everyday use and cleaning

Because bottles and parts should always be thoroughly cleaned before sterilising, wash everything with mild washing-up liquid first, then dismantle each bottle into its component parts before running a cycle. The steriliser itself wipes down easily and is dishwasher safe, so keeping the unit clean adds little to your routine. It's made from BPA-free, microwave-safe materials.

Best for

The NUK Micro Express Microwave Steriliser is a great option for parents who:

• Want a fast, chemical-free way to sterilise feeding items using a microwave they already own
• Sterilise regularly and need room for up to four bottles plus accessories in one go
• Prefer a compact, few-part unit that's easy to store and clean

It may not be the best fit if you:

• Don't have a microwave with the interior space it requires
• Need a unit that also warms milk, as this device only sterilises
