Does the Demigoddess Mini er work with all major breast pumps?

Yes! Demigoddess Mini er is compatible with most major narrow neck pumps without an adapter. The er also pairs SO well with wearable pumps. All you need to do is pour your milk directly from the pump into the er.

Does the Demigoddess Mini er come with a pump or pump parts?

No, our Breastmilk ers do not come with a pump or pump parts, but they are compatible with all major pumps/adapters (see FAQ #1). This allows you to choose the pump that is best for you.

How long can I store my milk in the Demigoddess Mini er?

They can safely store your milk for up to 16 hours. The Academy of Breastfeeding Medicine states that breastmilk can be kept at 59ºF for up to 24 hours, and the Mini er works to keep your milk at that temperature or less for up to 16 hours.

How does pumping warm milk into a thermos cool it and keep it cold?

Our dual-chamber cools milk efficiently. Fill one chamber with ice and splash of water to begin cooling. As it melts, it transfers cold temperature through the er walls. An efficient, natural way to keep milk cool without chemicals or ice packs!

Is reimbursable with HSA, FSA, or HRA?

Yes! Use your card to get reimbursed by your provider.

When Lisa returned to work after having her son, she found pumping difficult for a million reasons. And safe storage was one of them.

Her days were often longer than 8 hours. She traveled a lot. She was a just-enougher and couldn't risk wasting even an ounce. A cooler and chemical freeze packs weren't going to cut it.

So she fixed it. She worked with a team of experts and engineers to create the er - the first of its kind (and still the best)!
