Our exclusive patented Ameda HygieniKit, creates one of the most effective milk collection systems available today. It helps mothers provide the purest milk possible to their babies. The kit’s unique silicone diaphragm acts as a barrier, separating the user from the suction source. This helps ensure milk purity by preventing contaminants from coming in contact with collected breast milk and prevents milk back-up so tubing and pump require little to no maintenance. It also easily converts to manual pumping with the One-Hand Breast Pump (not included).
