Quick answer
Choose microwave sterilising bags for travel and small kitchens, and a microwave steam steriliser for daily bottle feeding at home.
Why space and routine matter
The biggest difference between these two options is how they fit into your daily routine. A microwave steam steriliser takes up counter space but offers a dedicated, ready-to-use station. Sterilising bags are compact and disposable, making them ideal for occasional use or when you're away from home.
Both methods are chemical-free and kill 99.9% of bacteria, but the time and effort differ. The Philips Avent unit sterilises in about 2 minutes, while Vital Baby bags take roughly 3 minutes per cycle. Neither requires electricity beyond your microwave.
Cost and value over time
The Philips Avent Microwave Steam Steriliser costs around $33.49 and is a one-time purchase that lasts for years. Vital Baby bags cost $4.64 per pack and give you 150 uses, but you'll need to buy new packs once they run out. If you sterilise several times a day, the steriliser quickly pays for itself.
For occasional use such as once-a-week sterilising or trips, bags are more economical upfront. For daily use, the steriliser is cheaper per use after just a few months.
