Who is this product for?
If you notice water or condensation in your breast pump tubing: it is imperative to change your tubing and your backflow protector membranes that protect your breast pump.
If you have purchased a used kit or use your equipment intensely: change these membranes regularly to prevent a loss of suction quality and motor wear. Replace membranes every 6 weeks for multi-daily users, every 2 months for frequent users, and as soon as you notice any alteration in the silicone's quality.
Advice
Are these the membranes I need?
YES IF:
- I have a Spectra breast pump: S1, S2, Synergy Gold, Synergy Gold Portable, or S9
- I have a Lupa Asymmetry breast pump
- I have a Maymom connector with a backflow valve system
