Like all Spectra pumps, the S1 Plus is a closed system, which means a physical barrier between the milk and the pump ensures hygiene and motor performance. The completely flexible, one-touch button and digital controls allow you to set the speed and rhythm most effective for your body. The suction is adjustable in both let-down and expression modes.

Important note regarding this upgrade breast pump: The Spectra S1 Plus is a breast pump model that includes upgrade features such as a rechargeable battery or other convenience items. Insurance covers a portion of the cost of this pump, but you are responsible for paying the remainder.
