Purchased new around January 2025, used for about six months, and the filter has not been replaced. I cleaned it regularly, but some marks remain. This is the nature of the product, and they appear after using it a couple of times from new, so I hope you understand. The outer box is not included. Everything in the photos is what's included. - Brand: Pigeon - Model: Bottle Sterilizer - Features: Includes a stand for sterilizing baby bottles - Control Panel: Digital control panel - Internal Structure: Hygienic internal design
