How to Choose the Right Breast Pump for You

Your pumping needs are unique, and so is the pump that will suit you best. Here’s a quick guide to help you choose between the Spectra S2 and S9:

• Choose the Spectra S2 if:
  • You’ll be pumping mostly at home.
  • You need strong, hospital-grade suction.
  • Portability isn’t a priority, but comfort and efficiency are.

 

• Choose the Spectra S9 if:
  • You need a lightweight, compact pump for travel or work.
  • You’re looking for cordless convenience with decent suction.
  • You want flexibility without being tied to an outlet.

Both pumps offer gentle, adjustable suction and closed-system hygiene, so you’re not choosing between safety or quality. You’re choosing what fits you best.

How to Clean and Care for Your Spectra S2 and S9 Breast Pump

Keeping your Spectra S2 or S9 clean is essential for your baby’s safety and for maintaining each pump’s suction performance. While the cleaning basics are similar, a few small details help you care for each model effectively.

• Rinse after each session: Remove and rinse all milk-contact parts (flanges, valves, bottles, backflow protectors) from either model under cool water to prevent residue from drying.
• Wash with gentle care: Use warm water and a mild, baby-safe soap. For the S9’s smaller, travel-friendly parts, pay extra attention to tiny connectors.
• Sterilize when needed: In the early weeks, sterilize once daily, especially if your baby is newborn or premature. For the S2, you can use boiling water or steam bags; for the S9, stick to manufacturer-approved methods to avoid heat damage to portable components.
• Dry fully: Air-dry parts on a clean rack or towel before storing, ensuring no moisture is trapped in S9 tubing or S2 backflow protectors.
• Store safely: Keep clean parts in a covered container. Having a second set of parts for each model can make on-the-go or night pumping easier.

Tip: Spectra’s closed system helps keep milk from backing into the tubing, but if condensation builds up, run the pump for a few minutes after use to dry it out.
