Philips Avent Microwave steam steriliser
A small, cheap microwave box that steam-sterilises four bottles in a few minutes and fits a cupboard.
MamaLoop mums pick
We researched microwave sterilisers because they do the same job as an electric unit for a fraction of the price and bench space. This one holds up to four Philips Avent bottles, takes two to six minutes depending on your microwave's wattage, and keeps the contents sterile for up to 24 hours if you leave the lid closed. Philips Australia buyers rate it 4.7 out of 5. Trade-offs: it suits Avent bottles best, wider bottles from other brands may fit fewer, it needs a microwave big enough to hold it, and the steam and water are very hot when you open it.
