Compatibility: This full milk collection cups replacement kit is only compatible with the Momcozy M5 wearable breast pump – it won’t work with other models. Important: these are not original Momcozy accessories; they’re high-quality replacement parts made by APMOOM, designed for a perfect fit and reliable performance with your pump.

Premium Materials: Crafted from food-grade silicone, these replacement pump parts are durable, leak-proof, BPA-free, and naturally soft with no odor. They’re gentle on mommy’s skin and safe for baby, ensuring peace of mind during every use.

Easy to Clean: After each use, wash the duckbill valves and diaphragm (compatible with Momcozy M5) with warm soapy water and rinse thoroughly. For deep cleaning, sterilize them in boiling water or steam at ≤100°C (212°F) for 5–10 minutes. Avoid using hard brushes—simply use your fingertips to gently scrub instead.

Increased Efficiency: The M5 wearable breast pump milk collector set is designed to boost your pumping efficiency. The silicone diaphragm’s anti-backflow design prevents milk from flowing backward, ensuring clean, long-lasting use—no contamination. Meanwhile, the duckbill valve’s anti-overflow design ensures milk flows downward only, keeping the collection process mess-free and hygienic.

Important Note: Do not sterilize pump parts using a microwave or UV sterilizer. High temperatures over 110°C (230°F) can shorten their lifespan and create safety hazards. For best performance, replace parts every 3 months or as needed.
