The pump helps mothers provide the purest milk possible to their babies.  The kit's unique silicon diaphragm acts as a barrier, separating the user from the suction source.  This helps ensure milk purity by preventing contaminants from coming in contract with collected breast milk, and prevents milk back-up so that tubing and pump require little or no maintenance.  The Hygienikit offers mothers the choice of single-or dual-pumping.  It also converts easily to manual pumping with the One-Hand Breast Pump.
