What to Look For in a Sterilizer

Drying Function: Wet bottles can harbor bacteria. A built-in drying cycle or HEPA filter keeps everything perfectly dry.

Compatibility: Check if the sterilizer fits your bottle brand (wide-neck, narrow, or breast pump parts).

Ease of Cleaning: Removable trays and descaling alerts make maintenance simple.

Steam sterilizers are the most popular for their speed and affordability. UV models are great for long-term use and energy efficiency.
