- Safe and Hygienic Materials: Crafted from BPA-free and food-grade silicone, these pump parts are not only safe and soft to the touch but also completely odorless. They provide the utmost safety for both you and your baby, letting you pump with peace of mind.
- Pump Efficiency: The diaphragms help maintain a secure seal to prevent milk leakage during pumping, while the duckbill valves efficiently channel your milk into the container, minimizing waste and ensuring every drop is saved.
- Convenient Cleaning: Designed with busy moms in mind, all parts can be quickly and easily washed with warm soapy water and thoroughly rinsed. For deep sterilization, they can withstand steam, boiling water, or microwave steam bags, offering multiple ways to ensure hygienic milk collection.
