From a Lactation Consultant’s Perspective
How it Holds Up Professionally
Spectra pumps mirror hospital-grade efficiency with up to 270–300 mmHg suction and adjustable settings—critical for effective emptying and maintaining supply These customizable features are essential for a tailored and comfortable pumping experience.
What I Like
Wide suction range allows moms to mimic baby's natural feeding rhythms.
Rechargeable S1 allows mobility—whether at home, work, or traveling.
Closed system reduces risk of contamination and simplifies cleaning.
Potential Concerns
The S2 lacks portability, making it less practical for on-the-go use
Limited flange sizes mean moms may need to purchase extra for optimal fit
The weight and size can be bulky compared to compact or wearable pumps
Pro Tips for Best Results
If nipples feel sensitive, experiment with the low-end suction or use a silicone insert.
To boost output, alternate between massage and expression, and consider combining with hand massage.
Keep extra valves, membranes, and compatible flanges on hand for easy replacements.
