The Spectra S1 Breast Pump boasts many great features, and like all Spectra pumps, is a closed system – a physical barrier between the milk and the pump ensures hygiene and motor performance. The S1 is intended to rival all other personal-use breast pumps, and even surpass them with some of its innovative features designed to make life easier for nursing mothers. With a maximum suction strength of 270 mmHg and the ability to be used as a single or double pump, you can also set the pumping program to the speed and rhythm most effective for your body. This very quiet pump has “massage mode” – a short, shallow mode designed to stimulate mom’s letdown reflex. The Spectra S1 Plus pump can then be switched to expression mode – a deeper, slower pattern of suction that mimics how babies nurse. For women who find it hard to get a letdown when pumping, this feature really helps, and you’re able to switch back and forth between modes as needed. The suction is also adjustable in both letdown and expression modes.
