Maymom Membranes Compatible with Medela Breastpumps, Suitable for Lactina, Manual Freestyle, Symphony, Swing, Pump in Style Pumps, Part # 87088 (White, 16pc)

Cost effective replacements. It is important to replace these regularly and these fit great.

Fits exactly in my medela pump. Suction is great and awesome value pack. Much better deal than the name brand and works just as great.

I bought these when my Medela PISA stopped performing as well as I would like. I replaced all of the valves and membranes and it's performance immediately improved. Honestly, I should replace these more often. I've had no problems with these since I purchased. They appear to be made well and none have ripped.

I exclusively single pump, so my whole setup gets a lot of use. I have to change the membrane weekly to ensure optimum yield (recommendation for double pumping is usually once a month for supplemental pumping. So at 6-8 sessions a day, I would change mine every two weeks if I double pumped), so go through them quickly. They fit perfectly on Maymom valves or those directly from Medela. Best part of this is the price!

These work just as great as the name brand, but for a fraction of the price. I pump at work four days a week. I have been back to work for 3 months and have not had a problem pumping/keeping up my supply. It is nice that these come in a value pack because it is recommended that they membranes be changed fairly frequently to maximize pumping success..

My pump seemed to be losing suction. I'd had my membranes for a while, so I knew that while it could be the motor going out (my pump is powering through the second kiddo), I may just need new membranes. These increased the suction so much that I had to turn the suction on the machine down from where I usually have it, so I'd say they work even better than the Medela brand. They seem thicker and less likely to warp as quickly, so maybe that's why. I will buy more of these when I need to, and save money over the pricier Medela ones.

Can't tell the difference between these and the Medela brand that comes with the pump. Nice to have extra as backup, but I'm not going through them very quickly as they hold up very well.

Bought these to replace the membrane on my medala pump and they work perfectly
