How often should I replace my eufy Sizing Inserts?

Do the eufy Sizing Inserts affect the suction power of my breast pump?

Using the correct size eufy 21mm Sizing Inserts is crucial for maintaining optimal suction power of your breast pump. A proper fit enhances the seal between the insert and the breast, contributing to effective milk flow. If the inserts are too small or too large, it might lead to decreased suction efficiency.

How do I clean and maintain the silicone sizing inserts?

Cleaning the eufy 21mm Sizing Inserts is simple. You can rinse them with warm water and mild soap after each use to ensure they remain hygienic.
