Customer Questions & Answers
-
Question:
What are the eufy Security Breast Pump S1/S1Pro/E10/E20 15mm Sizing Inserts made of?
Answer: The eufy Security Breast Pump Sizing Inserts are crafted from high-quality silicone.

Simply remove the existing sizing inserts from your eufy Security Breast Pump and replace them with the new silicone inserts by pushing them into the designated openings until they fit snugly. This design allows even first-time users to easily switch inserts without needing any tools or assistance. -
Question:
Are these sizing inserts compatible with other breast pump brands?
Answer: The eufy Security Breast Pump Sizing Inserts are specifically designed for the eufy Security Breast Pump models S1, S1Pro, E10, and E20. While they may look similar to other brands' inserts, compatibility with other pumps is not guaranteed.

Question:
How do the 15mm sizing inserts improve breastfeeding efficiency?
Answer: The 15mm sizing inserts are engineered to provide a perfect fit, which enhances suction capabilities during pumping. A better fit means that less air enters the breast shield, leading to a more efficient milk flow and ultimately a faster pumping experience.

Question:
Can I clean the silicone sizing inserts easily?
Answer: Absolutely! The silicone material is not only durable but also easy to clean. You can simply wash the sizes inserts with warm, soapy water, or place them in the top rack of your dishwasher for a thorough cleaning. Regular cleaning is essential to maintain hygiene, especially for nursing mothers, ensuring that the inserts remain safe for use. -
Question:
How do I know if I need a different size insert?
Answer: Choosing the right size insert is vital for maximizing both comfort and effectiveness. If you experience discomfort, pinching, or poor suction while pumping, it’s a sign that the current size may not be ideal. Consider measuring your nipple diameter and comparing it to sizing charts often provided by the manufacturer to determine if switching to another size would be beneficial. -
Question:
What is special about the silicone material used in these inserts?
Answer: The silicone used in the eufy Security Breast Pump Sizing Inserts is specially formulated to be both soft and durable. This ensures that the inserts are gentle against skin while providing robust support during pumping sessions.

Are these sizing inserts reusable?
Answer: Yes, the silicone sizing inserts are designed for multiple uses. As long as they are maintained and cleaned properly, they can be reused for extended periods. This feature makes them both economical and practical, enabling mothers to keep their pumping experience consistent without the need for frequent replacements. -
