Dr. Brown's™ Membranes for Customflow™ Double Electric Breast Pump or Manual Pump

The membrane seal on these is noticeably tighter than the originals, which made pumping feel much more efficient right away. Installation took just a few seconds with no fuss.

Had to buy these as replacements and they fit perfectly—snap right into place without any fuss. Pump is working like new again, suction feels solid.

I’d been worried about losing suction, but swapping in these closed-system membranes fixed the issue immediately—no more leaking during midnight feedings. The fit was snug right out of the pack, and they’re holding up well after several washes.

I was worried about getting a good seal after losing a membrane, but these fit my pump perfectly and the closed system keeps everything clean. They work just like the originals.

These membranes fit perfectly and immediately restored my pump’s suction to like-new strength. I appreciate how easy they are to snap into place and clean between sessions.

I was worried my pump would lose suction over time, but swapping in these membranes made it feel brand new. They fit perfectly and the closed-system design gives me peace of mind about keeping milk from backing up.

Finally found these replacement membranes at a reasonable price—much easier than sterilizing the old ones endlessly. They fit perfectly and the suction feels just like the originals.

I’ve been using these as backups for my pump and they snap on securely without any air leaks. The closed-system design makes cleanup a breeze, and they work exactly like the originals. Great to have spares on hand for those late-night pumping sessions.

They fit perfectly on my pump and restored suction instantly—way better than trying to clean the old ones. I love that they’re closed-system, so no milk gets stuck in hard-to-reach crevices. Already ordered a backup set.

I bought these to replace the original membranes after a few months of heavy use, and the suction feels just as strong as day one—no leaks at all. They clicked right into place on my electric pump without any fuss.
