Frequently Asked Questions
What is the difference between Spectra S1 and S2?
The S2 has identical pumping performance but requires an AC outlet. The S1 adds a rechargeable battery that lasts approximately 3 hours per charge. The battery is the only meaningful difference. Choose S1 if you pump away from outlets; choose S2 if you always pump near an outlet and want to save $50.
Is Spectra covered by insurance?
Under the ACA, most US health insurance plans must cover breast pumps. The Spectra S1 is covered by many plans. Check with your insurance provider and durable medical equipment supplier before purchasing.
What is a closed-system pump?
A closed system has a physical barrier (backflow protector) between the milk collection area and the motor. This prevents milk from entering the tubing or motor, making the pump hygienic for multi-user situations and more durable long-term.
